14 Best Weed Jars and Storage Containers for Weed in 2020

There are many options when it comes to storing your cannabis and keeping them potent and clean. Over the years, many cannabis growers or users have eventually learned the importance of storing weed the right way. The most common method among growers used to be storing weed in large plastic garbage bags, then putting them inside tubs or bins. But eventually, many growers have realized that their storage method isn’t exactly pertinent to their process. Which is why buds are extremely dry or weak when you get them. Many cannabis growers also longed to secure more reliable and sealed storage since some states mandate that the cannabis is kept in airtight and properly sealed jars or containers. Proper and appropriate weed storage method should help mitigate the evaporative loss of potency or drying out. In writing this post, we carry the goal of being able to provide you with great choices for weed jars and best storage containers for weed.

Ideal conditions for storing your weed

Best relative humidity (RH) for storing Cannabis

Relative humidity (RH) is the ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a prescribed temperature. The best relative humidity when it comes to storing cannabis is 55% to 62% RH. Studies have shown that cannabis will retain a higher terpene and cannabinoid content when this range of moisture is present for a prolonged period of time. Storing your cannabis in this RH range will surely retain a more robust flavor and a great high.

Ideal Temperatures for Storing Cannabis

Fungi and bacteria are very harmful not only to cannabis but to other plants as well. They promote the growth of mold and mildew and you would never want them on your cannabis. These molds grow at temperatures above 75 degrees and these harmful organisms can ruin your weed. That is why your cannabis needs to be stored at temperatures below 75 F or 24 C. Find and store them in an area where the temperature doesn’t fluctuate too much but remains around 65 F, or within ten degrees of 65 F at all times. This can be in areas such as a cupboard, drawer, or closet.

Light Exposure

Previous conducted studies like “The Stability of Cannabis and its Preparations on Storage,” conducted by J.W. Fairbairn, J.A. Liebmann, and M.G. Rowan from the Pharmacology Department in the School of Pharmacy, University of London in 1975 found that that the best long-term weed storage method required keeping cannabis at room temperature in a dark and sealed container. It is ideal that you limit light exposure to weed that you intend to store. Light is actually considered to be the main factor that causes weed degradation. UV rays and intense light from many sources will break down cannabinoids. Therefore, choose a dark place to store your weed, a closet or drawer that doesn’t receive much light. Also, use a dark glass container when storing batches of your weed.

Vacuum Sealing

Some weed users and growers may not trust the use of vacuum sealing when it comes to storing weed. While some claim vacuum sealing, properly, with plastics which don’t contain BPA, is a great way to keep your bud fresh for a very long time. Others claim that plastic will ruin your weed and vacuum sealing will suck out your cannabinoids and damage your trichomes. Although, you can vacuum seal smaller individual doses, then store the individually sealed doses in a glass jar in a cool dry place so that it is still protected from temperature extremes and light exposure. You could even use a light-resistant plastic; however, you would need to be extremely careful to know the chemicals in your plastics because they can end up in your weed.

Weed storage Dos and Don’ts

  • Remember to use an airtight container. A clear mason jar will be okay but remember to store it in a dark cupboard or cabinet.
  • Keep your stored weed away from light.
  • It is ideal to use containers made of materials with a neutral electrical charge. An example is a glass jar. This is to avoid static.
  • Always keep different strains in separate containers to avoid mixing chemical compounds and aroma.
  • Store filled containers in a cool and dry place. It should be at 70 degrees Fahrenheit and away from direct sunlight.
  • Maintain an optimal range of 55% to 62% relative humidity (RH) in the storage container.
  • Maintain relative humidity by using Boveda packs or VaporBeads.

Don’ts

  • Store weed inside a chiller or freezer. This will result in dry, brittle, and tasteless weed.
  • Keep weed in tin cans. These tin cans let in too much oxygen, which degrades THC over time.
  • Store your weed without a humidity element.
  • Keep weed in sandwich bags. The plastic has static that will pull off the trichomes, which contain the cannabinoids.
  • Add fruit and mix them inside your weed jars. This will eventually create a too high RH and will result to molds in your buds.
  • Use sandwich bags for storage, they generate a static charge and will result in your buds having an unpleasant plastic taste. Your weed will also be smelled since they are not airtight.
  • Keep near heat and electricity sources. They will dry out your cannabis.
  • Pre-grind and store for a very long period of time.

Things to Consider Before Buying a Weed Jar or Storage Container

There are a few things to consider before you invest in one of these products. Below are some aspects to keep in mind to ensure you invest in the right model.

Its Size

An important thing to consider is the size of the weed jar or storage container. Sometimes these products might be too big or too small for your needs. Because of this, it’s ideal to closely look at the size. For instance, if you plan to have a lot of weed on hand and don’t want to transport it around, a larger jar or container might be best. On the other hand, if you want a jar or container to carry around with you in a bag, a smaller and more compact size might be ideal.

If it’s Airtight

You should also always make sure a weed jar or storage container is airtight. This will prevent moisture from seeping into it which can ultimately destroy the contents inside. Moisture can invite mold and harmful bacteria as well as reduce the flavor of your weed. Due to this, always make sure the jar has an airtight lid.

If it Protects Your Weed From Sunlight

Just as with moisture, sunlight can also be a problem. The UV rays emitted by the sun can cause your the color of your weed to fade which ends up leading to it being less flavorful. If you plan to keep your weed jar or container in a sunny spot, it’s a good idea to make sure it has a UV protection feature.

If it’s Smell-Proof

Another thing to consider is if the model is smell-proof. While a model might say it’s airtight, this doesn’t always mean it will help to prevent smells from escaping. Because of this, it’s important to ensure that the jar or container doesn’t leak smells when you use it.

Other Things to Keep in Mind

There are a few other things you’ll want to keep in mind before investing in a weed storage container or jar.

The Price

One is the price of the product. Depending on your needs, you’ll either want to invest in an affordable or expensive one. If this is your first time buying a weed container or weed jar, you might want to start out with a cheap one just to make sure it works for you. On the other hand, if this isn’t your first time, a more expensive one might be ideal.

Clean it Out

It’s always a good idea to make sure to clean your jar or container out often. This will not only help to prevent odors from forming, but can keep your weed fresh. Leftover particles inside might end up destroying the flavors of fresh weed. It can also be a hazard to your health as dangerous resin could coat the walls of the jar or container.

To clean out your storage container or jar, you can take a clean cloth or paper towel and wipe it out. This method is perfect if you don’t want to do a deep clean.

For a more intense clean, you can rinse the jar or container out under warm soapy water and then dry it out. Keep in mind though that this might not be possible for all container or jar types as it could ruin them. Because of this, make sure to check beforehand.

Be Careful with It

While these items are usually very durable, you still want to make sure to be careful with them. Too much bumping around could lead to scratches on its exterior ruining its appearance. It could also mean that the container or jar is more likely to fall out as it’s not being carefully watched. Due to this, just make sure to keep a close eye on it, or keep it in a special pocket or bag to help better protect it.

Don’t Put Extra Materials Inside It

As mentioned in the section in the beginning of this article, it’s a good idea to not put extra materials, like a plastic bag, inside of the product. This will not make it a bit harder for you to get your weed out, but could lead to static which can hurt the taste of the buds. It’s always important to put the weed inside of the containers or jars by itself.

Conclusion

Growing cannabis is not an easy task, and we know that. Which is why it is really important to store and keep them fresh in a good container. Finding a great stash jar or container might not be an easy task, especially for the beginners. However, we are pretty sure that after you read this post, you already have an idea which container is best for you. You have the option of choosing glass, metal or even plastic to store your weed. Storing your stash especially if you are a grower, using weed for medical purposes, or just a heavy stones, or someone who handles a large amount of weed is an important part of preserving the taste, aroma, and freshness of good cannabis. Therefore, invest in a good storage container to ensure you enjoy the full cannabis experience. Having a great permanent storage container also makes it more hygienic and easier for you to find your stash.

This drying & curing tutorial is part of our “how to harvest cannabis” series:

Why Do Growers Dry and “Cure” Cannabis Buds?

Harvest time!

Your buds are ready for harvest, yet your job as a grower is not quite over yet. You still need to put your newly harvested buds through the cannabis curing process.

In order to ensure the best quality for your freshly harvested buds, you must prepare your buds with a process known as curing, which involves drying your buds slowly in a controlled environment, then keeping buds in glass jars over the course of a few weeks to let certain natural plant processes occur. The drying/curing process causes buds to smell better and for effects to feel more potent. It also reduces harshness.

Optimal Drying Environment:
Room Temperature – Around 70°F (21°C)
50% Humidity

Optimal Environment in Jars (Curing):
Room Temperature – Around 70°F ( 21°C)
58-65% Humidity

Growers cure marijuana buds because they will not achieve their peak potency and quality if they’re uncured. If you started with great genetics and you’ve taken care of your marijuana plants properly during their life, then curing is what makes the difference between “just okay” and trophy-worthy buds.

Dry & Cure Cannabis Properly for Highest Quality Buds

A big part of why buds from medical marijuana dispensaries or cannabis cups often seem so special is they have been expertly dried and cured. People who have never experienced buds prepared this way are often amazed by the smooth, pleasant experience of slow cured buds. Here’s a quick review:

Why Do Growers Dry & Cure Buds After Harvest?

Here’s what drying and curing cannabis properly does for you…

Breaks down chlorophyll and dramatically improves taste / smoothness of buds

Gets rid of the unpleasant “fresh hay” or “cut grass” smell which is common on newly harvested buds

Brings out the subtle flavors and unique smell of your cannabis strain

Reduces “harshness” in buds; you’re less likely to start coughing or get a headache

Buds are less likely to cause anxiety, racing thoughts, or paranoia

Reduces the chance of mold or bacteria growing on your buds

Curing seems to actually increase potency! Read on to learn more…

In most cases, a proper cure will change the subjective effects of buds. There is something that happens during a slow curing process which changes the exact composition of cannabinoids and terpenoids. This changes how buds make you feel.

Try smoking buds directly off the plant vs smoking those same buds after they’ve been dried/cured. The best way to understand the difference is to try it for yourself! 😉

Many growers feel that drying buds slowly and proper curing will actually make buds feel more potent up to a point. Growers also report that properly cured buds are much more pleasant to smoke, vaporize, or turn into edibles. This is likely due to how cannabinoids and terpenoids are altered during the curing process.

So now you may be wondering…

How do you dry your marijuana buds slowly?

How long do you dry your buds for and what’s the best drying method?

How do you cure buds perfectly every time, without leaving anything to chance?

Get the answers right here!

Note: This article covers the tried-and-true steps for traditional curing. This is the most used and well-studied way to cure your buds. However, there are other possible methods including water curing which I personally don’t have any experience with.

Drying & Curing Marijuana: Overview

Curing begins as soon as you cut down your plant. So in order to get the most from curing, you need to master the process of drying your buds.

An important part of the curing process happens during the first few days, as you begin drying your buds. During this initial drying phase, the main goal is to let your buds dry out relatively slowly (usually 3-7 days) while protecting buds against mold and bacteria growth.

Curing starts as soon as you cut down your plant!

Most growers trim their buds and hang them upside down to dry until the outsides of buds are dry and the small stems snap when you bend them. Basically, once your buds will pop off you’re ready to go 🙂

A relatively slow drying process (along with smart curing practices) gives you the best benefits. It doesn’t need to take forever, but any time you “speed dry” your freshly harvested buds you’re losing many of the benefits of curing. However, your buds are still improved by curing even if you overdry your buds or dry them a little too quick.

Note: If you use heat to speed dry your buds (microwave, oven, etc), buds will really taste terrible.

Here’s an overview of the harvest / drying / curing cannabis process. Click for a bigger picture and keep scrolling down for more complete instructions…

Now I will walk you through a step-by-step process so you can produce a professional cure every time, with no guesswork involved.

This method will work for you even if you’re just starting out and have never cured buds before. No matter what previous experience you have curing buds, this will show you how to ensure they come out connoisseur-quality every time.

How to Perfectly Dry & Cure Your Marijuana Every Time

Wide mouthed mason jars – 1 quart size. These are sometimes labled as “32 oz” jars.

Place to Dry or Drying rack (optional) – I usually hang my buds from clothes hangers in my closet but you can hang buds from almost anything! String and creativity go a long way 🙂 It’s only recommended to use a drying rack if there’s high humidity or a lot of buds to be dried in a small space, because a drying rack can dry buds too quickly in average humidity conditions.

Hygrometer (optional) – I like the Caliber IV Hygrometer because it easily fits inside quart mason jars. This measures the humidity of the air inside your jar, so you can make sure it’s not too humid or too dry for optimal curing.

Humidipaks (optional) – Boveda Medium 62% packs are cheap and specifically formulated for storing cannabis so it does not dry out or get crispy

Step 1: Cut down your plant

Some growers cut the plant down at the base and hang the whole plant upside down to dry. Others will cut off branches and hang them to dry. Still others will cut off individual buds so they can lay them out and dry them on a mesh screen or rack.

How should you cut down your plant?

It’s tough to mess this part up! You can harvest your plant a piece at a time, and I’ve also seen growers trim their buds while they’re still on the plant so they can hang their whole plant upside down to dry.

I personally cut down branches one at a time. Here’s a plant that is halfway through being harvested.

Step 2: Trim away extra fan leaves

Before you start drying your buds, most growers will trim away extra leaves.

At the very least, you should trim away all your big fan leaves, though many growers also trim down the little leaves that grow on the buds.

This improves the appearance of your buds, and will provide a smoother experience. Too much leafy matter can make buds more harsh.

The amount of leaves you trim off is due to personal preference. However, like the last step, you want to leave more if you live in a very dry area. You want to cut off as much as you can if your area is humid, to help speed up the drying process and prevent mold. If it’s very humid where you live than you may consider removing buds from branches while drying.

If Your Humidity Is…

  • Dry (Under 30% RH) – You might consider leaving more leaves on your plant while trimming to help slow down the drying process. The more plant matter left behind, the lower the buds dry. For example you could trim your buds but leave extra fan leaves, or possibly even not trim at all until after drying.
  • Average Humidity – If you never really notice the humidity where you live chances are it’s perfect for hanging your cannabis upside down to dry 🙂
  • Humid (Over 60% Humidity) – If it’s very humid where you live, you might consider actually separating buds from branches after trimming and put them on a drying rack or mesh to help them dry in the high humidity without running into problems with mold (here’s how one grower dried in high humidity)

I recommend trimming your buds while wearing disposable gloves, to prevent your hands from getting covered in sticky resin.

You may want to save your trim (resin-covered leaves or larfy buds you’ve trimmed off). These extra leaves are not good to smoke by themselves, but after being dried, the trim can be processed to make marijuana butter or other cannabis extracts.

Right after you harvest your plant, it’s important to start drying your buds slowly, over a couple of days to a week or more.

Step 3: Begin the slow drying process

Why should you dry your cannabis slowly? Drying your buds is the first part of the curing process, and important!

Optimal Drying Environment:
Room Temperature – Around 70°F (21°C)
50% Humidity

Here are some ideas to adjust your environment:

  • Air Conditioner – Cools Air & Lowers Humidity
  • Evaporative Cooler – Cools Air & Raises Humidity
  • Dehumidifier – Heats Air & Lowers Humidity
  • Humidifier – Heats Air & Raises Humidity
  • Heater – Heats Air & (Usually) Lowers Humidity

Buds which are quick-dried in a dehydrator/stove, via dry ice, or in a microwave taste terrible, smell even worse, and often leave you with a migraine or paranoia. When you quick-dry your buds, you are completely skipping over the most important part of the curing process!

In fact, even drying your buds in mildly hot temperatures, like 85°F (30°C), can burn off valuable smells (terpenes) & possibly certain cannabinoids.

Curing you cannabis properly makes up almost 50% of your final bud quality!

You can take the best cannabis in the whole world but if it’s not cured it’s going to be mid-quality at best!

There are many ways to dry your marijuana buds.

Hanging buds upside down to dry is considered the “standard” way of drying. You can get creative when coming up with ways to hang plants upside down.

You can dry buds by hanging them upside down from clothes hangers, string, almost anything you can think of. You can even hang the entire plant upside down. Personally, I prefer to hang buds upside down for the drying process.

However, you can dry your buds via many different ways!

Some growers place their freshly harvested buds on a drying rack as pictured to the right.

A drying rack will dry your buds faster than most of the other methods because the stems are removed from the buds (and the stems contain a bit of water). Using a drying rack is the preferred drying method if you live in a humid area where mold is a problem, if you’re drying a lot of buds in a relatively small space, or if you have huge colas or buds that you’re worried might mold.

You can leave as much or as little stem as you want. The more you leave, the slower the dry.

Some growers dry their buds in paper bags or even by laying them out on cardboard.

I usually dry my newly harvested buds in my grow tent, or a closet

If you’re laying your buds on something flat like cardboard, it can create wet spots, and will leave an imprint on the sides of your buds where they touched the flat surface. That being said, cardboard can be a way to help people dry buds if they live in a humid environment because it will quickly pull the water out of the buds.

If buds are creating wet spots, you may need to rotate them every few hours so they dry more evenly. This is one of the reasons I prefer to use a drying rack if it’s humid, or hanging buds pretty much any other time.

If buds start to seem wet/soggy, or if you live in a very humid environment, you may need to use a small fan to create extra airflow in the drying area to prevent buds from getting too wet and causing mold. Never point a fan directly at your buds, only point it at a nearby wall. Even then, be careful of drying buds too fast with a fan! You should avoid using a fan unless it’s absolutely necessary because it can easily overdry buds. I’ve overdried an entire harvest by adding a fan before, so use with caution!

For those who live in extremely humid areas (where the high humidity in the air is preventing buds from drying even with a fan), there are more resources at the bottom of this article on how to dry out your buds properly. Learn how one grower was able to dry his buds even with 85-95% relative humidity in his area.

The most important aspect of the drying process is to dry them slowly, and in such a way that it’s easy for you to check on them regularly. So don’t hide them in the back of a closet that’s hard for you to get to. You need to be able to check on your buds every day, and more often is possible (especially during your first few harvests, until you know how buds dry in your personal environment).

Step 4: Continue drying until outsides of buds feel dry to the touch, and smaller stems snap instead of bend, usually 3-7 days. Buds will “snap” off without leaving a stringy trail.

If buds are dry sooner than 3-4 days, it may mean you’ve dried your buds a little too fast, but that’s okay! Live and learn for next time. It’s difficult to get things exactly right at first because the size and density of the buds, and your environment can vary so much! Even if buds have been dried too quickly, they still benefit from the curing process, but it may take a little longer than normal for buds to be fully “cured.”

If you accidentally remove all moisture from the buds (dry your cannabis for too long), the curing process slows down dramatically, or may even come mostly to a halt. However just like buds dried too quickly, overdried buds will still cure, but it takes longer.

When to jar cannabis buds?

When hanging your buds upside down to dry, your buds are ready to be placed in jars when the outsides of all the buds are completely dry to the touch, but not brittle.The bigger stems will still be bendy but the smaller stems will snap when buds are ready to pull down.

When buds are finished drying, you’ll be able to snap off the smallest buds with your fingers without leaving a “string” of plant behind. “Stringiness” means there’s still too much moisture inside.

Although the buds may feel overdry at this point, if the bigger stems are bendy it means there’s still water hidden inside that will work its way to the outside of the buds during the curing process. This is the perfect time to pull down your buds and jar them.

If you pull down your buds before the smallest stems snap, you’ll find they tend to be too wet once you put them in jars, so you’ll end up having to dry them more anyway. But if you can find a stem that snaps, it’s better to take buds down too early since it’s a lot easier to take water away than add it back.

With drying methods where the buds have been removed from the stems, it’s important to jar buds as soon as the outsides feel dry to the touch, before the buds dry all the way through, since there won’t be any stems to “hold onto” some extra water.

If buds were completely separated from the stems during the drying process, they’re ready as soon as the outsides feel dry to the touch.

It’s ideal to pull buds down at the right time because you can slowly draw out the moisture from the middle of the buds, which allows the curing process to continue. As long as the outside of your buds feel dry to the touch, it is unlikely for mold to grow. Mold generally grows where the outsides of your buds feel moist or damp to the touch.

Some growers choose to sample some of their buds at this point, but be aware that the smell, taste, and potency are not even close to optimal yet. Buds that haven’t been cured are also usually harsh, tend to bother the back of your throat, and give some people headaches. But don’t worry, your bud quality continues to improve as you cure the buds and help break down some of the “bad stuff” that you don’t want in your buds.

Step 5: Place your buds in jars

From this point, your goal is to store your buds in a controlled environment. You want to stabilize the relative humidity at around 60-65% when the buds are placed in an enclosed container. This is the correct environment to cure your marijuana buds to perfection. If you’ve taken your buds down when the smallest stems snap, but the larger ones bend, then chances are your buds will already create the perfect humidity when they’re in the jars.

Optimal Curing Environment (in Jars):
Room Temperature – Around 70°F ( 21°C)
60-65% Humidity

Place your dried cannabis buds in jars for the “curing” process

When the humidity is at 60-65%, your buds will feel completely dry on the outside, but won’t crumble or seem dusty in your hands (which usually means the humidity is too low).

Here’s how to jar your buds the right way every time, without any guesswork on your part.

The ideal storage containers for marijuana buds are wide-mouthed glass mason jars. These can be found pretty easily at big grocery stores, most craft stores, online, and at superstores (like Wal-mart). As cannabis cultivation has become more popular, these jars are appearing in more and more stores.

You want mason jars that hold 1 quart (labeled “Quart jars” or sometimes 32oz jars). Each of these jars will hold about an ounce of dried buds (usually about 0.75-1.25 ounces of bud will fit in one jar, but it can be more or less depending on the consistency of your buds).

One-quart glass mason jars have proven to be a great size for proper curing. Bigger jars are more likely to encourage mold – I’ve learned this one from experience 🙁 Other types of jars often don’t seal the right way, which can prevent buds from curing properly. For example, the type of jars that have a rubber seal don’t seem to cure buds right for me. I always use quart-sized glass mason jars, and you’ll see that the majority of growers do the same.

You want to fill each jar 75% full of buds, so there’s still a bit of air at the top. If you shake the jars, you want the buds to be able to move around. If they’re sticking together it means they’re still too wet and you should leave the lids off for a little while to help them dry out.

If buds are sticking together in clumps when you try to shake the jar, it means they still have too much moisture and need to be dried further. Just like when buds are too dry, when buds are too wet they slow down the curing process, but it’s even worse because it can cause mold. Never let buds sit in jars if they feel wet, or even moist on the outside!

Buds should always feel completely dry on the outside, and shouldn’t stick together. If you ever smell “ammonia” it means they’re too wet and bad bacteria is starting to grow

If you notice that any buds feel damp or moist, do not store them in the jars yet! Allow those buds to continue drying slowly until they start to feel dry on the outside before putting them in jars.If they’re already in jars and feel moist, make sure to leave the tops of the jars off until the buds feel dry again.

I know it’s tough to keep them from drying out all the way, yet not putting them in too wet. But if you follow these steps you’ll be able to get it perfect!

How much difference does the humidity inside the jar make?

More on curing buds in anaerobic conditions

Some growers cultivate strongly anaerobic conditions during the drying/curing process on purpose. For example, some indoor growers put their cannabis buds in jars while at least partially wet on the outside, causing extra bacterial growth. Buds cured in very wet conditions look different, smell different and produce different effects, but may be more harsh.

Another real-life example of curing buds in anearobic conditions is some outdoor growers will throw newly harvested cannabis buds in a pile while wet, leaves and all, and allowed it to sort of cook in place like a compost pile. After some amount of time, the buds are wrapped up and compressed for storage, often still partially wet, then cut up into bricks. This is considered a type of “brick weed.”

Example of “brick weed” cured in anaerobic (wet) conditions

Any curing process that involves letting buds stay wet and sealed up at the beginning produces weed with a different consistency and different effects. Buds become crumbly and they lose their green color after just a week or two, becoming more tan or golden. Many people agree that curing in anaerobic conditions can produce bud that is more “harsh” and this type of bud is generally considered “inferior.” To be fair to both sides, there are people I’ve met who prefer this type of cannabis because they like the slightly different effects.

That being said, curing buds while still wet can be unsafe by causing unwanted mold or a bad type of bacteria to grow. If you cure buds while they’re dry on the outside and moist on the inside, as stated in this tutorial, you can achieve the same mental and physical effects of anaerobic-cured weed without the harshness, simply by giving buds a little more time to cure.

If you want to safely get the effects of anaerobically cured bud, all you have to do is cure buds in jars for 2+ months. They start to slowly get a similar appearance and consistency of bud cured in anaerobic conditions, but instead of being harsh they actually get smoother over time. The mental and physical effects of long-cured buds also seems to get stronger as it’s cured longer (up to a point), giving similar heady and body effects that some describe as being a little “drunk.” Long-cured buds gives you the same benefits without the harshness or lack of safety. Because of that, I highly recommend avoiding sealing up buds that feel wet on the outside during the curing process!

Step 6: Curing (first few weeks): Open all jars regularly to inspect and air out buds

During the first few days, you may want to check even more often than once/day, especially if you are worried about mold or bacteria from too much moisture.

It’s important that you’re checking on your buds at least every 24 hours during the beginning stages, as described below. In addition to checking on your buds, it’s also important to open the jars once a day, because buds need fresh air as part of the curing process.

If you smell ammonia or the outside of buds feel moist, it means buds are too wet and need to air out before closing the jars again. If it smells more like cannabis every day, it means you’re doing it right!

For the impatient, this also gives you the opportunity to “try out” your new buds and see how they improve during the curing process 🙂

As mentioned already, the trick to a great marijuana cure is controlling the humidity of the environment. Ideally, you would like to keep your buds stored in an enclosed container with about 60-65%% relative humidity. This is the perfect amount of moist and dry to get the fastest and best curing process.

To be able to get a reading on your current humidity levels (so you can make sure they’re perfect every time), you may want to invest in a tool called a hygrometer.

I like the Caliber IV hygrometer, which is small enough to fit in your curing jars and can be found online for cheap. A hygrometer is more of a luxury than a necessity, though it will take out a lot of the guesswork.

As you can see in this pic, the Caliber IV hygrometers display both the temperature and the relative humidity in each curing jar. (click for a closer look)

Use a hygrometer for pro cannabis curing results, as it will allow you to determine exactly where you are in the curing process and spot possible humidity problems before they affect your buds. Even if you only have one, you can put it in different jars during your daily check to get an idea of the RH (relative humidity) in your jars.

Buds need some amount of time “to sweat” in the jar before you can get an accurate reading of how much moisture is really in the jars. Sometime buds which seemed dry when you put them in will feel damp and soggy when you check them a few hours later. This is because the moisture that was contained in the middle has spread out to the rest of the buds, and it means the buds need to be dried further.

A hygrometer will let you measure the relative humidity within your curing jars most precisely, but I was able to do this process for years without any extra tools just by following the general guidelines below for how buds should look/feel.

Overview of curing cannabis humidity requirements

For the first week, you want to air out your jars for a few moments at least once a day. Just open all the jars and close them again once a day. While the jars are open, check on buds to determine the current humidity levels. You may also take this time to shake the jars and move buds around, to ensure there are no moist spots, and buds aren’t sticking together in clumps.

This is what you’re checking for every time you open your jars.

Buds feel wet – Wet buds need to be placed outside the jar to dry for another 1-2 hours. Moist buds should not be touching each other! It is very important you react quickly if buds feel damp to the touch, as this is the most likely time for mold to grow.

> 70% humidity – When buds are too wet, your hygrometer will read greater than 70% relative humidity after buds are in jars with a hygrometer for 24 hours. If buds are very wet, you may see the humidity climb up this high within just a couple of hours. If you see the humidity rising on your hygrometer at a rate of 1% per hour or more, you may want open the jars early, or at least keep a close eye, as your buds are probably too moist.

Buds feel moist – If you shake the jar at this point, you may notice that some of your buds are still sticking together. You’re almost there, but buds are still a little too damp and you’re at risk for mold or anaerobic bacteria. If you live in a normal to dry climate, you may be able to get away with just leaving the top off the jars for 1-4 hours. If you live in a humid climate, you may have to take the buds out of the jars and lay them out until the outsides begin to feel dry again.

65-70% humidity – When buds are slightly moist, your hygrometer will read 65-70% relative humidity after buds are in jars with a hygrometer for 24 hours.

Buds are not wet, but also not brittle – You’re in the cure zone! Your buds may feel a bit sticky to your fingers. Buds should move independently and not clump together in big bunches when you shake the jars.

60-65% humidity – When buds are in the cure zone, your hygrometer will read 60-65% relative humidity after buds are in jars with a hygrometer for 24 hours.

Some growers prefer to keep it a little lower during curing, down to around 55%, especially if they’re curing a whole lot of cannabis, because it helps prevent the chance of mold or “moist pockets” in the jars.

At this point, some growers add a Boveda 62 Humidipak to their curing jar with the buds to help keep the humidity in the correct range during the rest of the cure. (More on Boveda 62 packs below)

Buds are too dry – Buds feel brittle and crumbly. At this point, there is not enough moisture in the jars for the curing process to continue at a normal pace, and buds tend to cure much more slowly.

Having Trouble Curing? Want to Prevent Problems During Your Cure? Get Boveda 62 Humidipaks

For those who struggle with curing even after going through all the steps in this curing tutorial, there’s a product known as a “Boveda 62” humidipaks which can help maintain the correct humidity in your jars. These are especially helpful at preventing the humidity from getting too low, even if the humidity is very low where you live. Some growers choose to use these every time they jar their buds to maintain the humidity in the 62% range.

Boveda Humidipaks (62% version) are specifically made for cannabis and can help maintain humidity at 62%, as well as rehydrate buds.

Humidipaks are used to regulate the humidity automatically. They were invented to keep cigars fresh in humidors (which is how they originally got their name), but the company now makes humidipaks that are specifically formulated for storing cannabis at the right humidity (as stated on their website). These are the Boveda Medium 62% Humidipaks.

Note: Boveda is trying to move away from the term “humidipak” these days for some reason, but it’s such a perfect name!

Here’s a picture of buds stored with a humidipak. You simply place the little pouches inside with your buds after they’ve finished drying.

Even when using Humidipaks, it’s important that you follow the rest of the steps outlined in this tutorial to ensure that your cure goes great.

Do you need to get Boveda 62 Humidipaks?

No. If you follow all the steps outlined in this article, you likely will not need Humidipaks. Most growers are able to cure their buds perfectly well without them.

However, they can be helpful if you will be curing your buds in an environment with the incorrect humidity, especially if the air is really dry where you live. They can also be helpful if you’re not used to curing and are afraid of messing it up.

Humidipaks also work very well for long-term storage. When we used them, they didn’t seem to lower the humidity when it was too high in our curing jars, but they did protect buds from drying out.

Will Boveda 62 packs reduce the smell of your buds?

We have never noticed that. Most growers seem to agree that these packs won’t reduce bud smell if they are added to the jars after the humidity has already been stabilized around 62% humidity for a few days.

Keep opening all jars at least once/day for first 1-2 weeks of curing

For the first 1-2 weeks, whether or not you’re using Boveda 62 humidipaks, you should continue checking your buds regularly and opening all the jars once a day.

Once you are sure buds have been steadily in the cure zone for a few weeks, you may start opening the jars just once/week or even less.

Re-Hydrating Overdried Buds

If you feel like you’ve overdried your buds, don’t panic! Sometimes it feels like buds are too dry even when there is still moisture inside. It’s a good idea to leave buds in jars for at least 2-3 days to see if moisture starts coming to the surface from inside. If buds still feel bone dry after a few days of being jarred, that’s when you might consider rehydrating buds.

Don’t Panic if Buds Are Too Dry!

If you’ve only got household items, trying to re-hydrate buds afterward is risky and probably not a good idea. Re-hydration increases the risk of mold, especially if using something organic, like an orange peel, so use something that’s meant to do the re-hydrating.

Boveda Humidipaks for Re-Hydrating Dry Buds

If you’ve been watching buds closely from the beginning, it is unlikely that buds will become over dry. However, if you have over-dried buds, one safe option to at least reduce the brittleness (freshen them up) is to add 62% Boveda Humidipaks to your jars, which will bring the humidity back up to 62% (they don’t work well for reducing humidity though – they can only raise the humidity and keeping it at the 62% level).

These will help slowly infuse moisture back into your buds and won’t affect the taste or increase the chances of mold.

Once the buds have been re-hydrated, you can remove the Humidipak if desired. Some growers have reported that leaving Humidipaks in jars during the first 4 weeks of curing can reduce the taste/smell of buds, though when we used Humidipaks during the curing process we didn’t notice any difference in smell or flavor.

Step 7: Long term storage

As long as buds remain consistently in the cure zone after several weeks, you can begin to open jars once/month.

Buds will continue to improve from curing for up to 6 months. After 6 months, further curing will not continue to have much effect. At this point, you want to prepare the buds for long term storage to maintain their potency for as long as possible.

For long-term storage (months), buds should be kept in air-tight containers (the wide-mouthed mason jars they’ve been curing in are perfect) and placed in a cool, dark environment.

For serious long-term storage (6 months or more), you may want to consider vacuum sealing your buds, or even better, storing them in your freezer in tightly packed mason glass jars!

Buds should feel dry and have been curing for at least 3 months before any attempt to store them long term. It is better to err on the side of buds being too dry when you’re going to store buds for a long time without checking on them. Even if buds get brittle, they can be “freshened up” later with a Humidipak.

Properly stored buds can retain a lot of their potency for years

After curing for a year or more after harvest, buds will tend to produce more of a “mellow” effect and will look a lot more beige than green, but other than that the effects stay mostly the same as long as buds are stored properly.

62% humidity – When buds are dry enough for long term storage, your hygrometer will read 62% relative humidity or slightly less. It’s important that buds are not wet at all before long-term storage, or they may mold!

A great way to make sure buds don’t contain extra moisture is to leave your cured buds in unopened jars for a few weeks first, to make sure the humidity reading is completely accurate before your store your buds somewhere you won’t be able to easily check. Adding a Boveda 62 humidipak to the jar will also help keep the humidity where it needs to be!

That’s it! Perfectly cured buds every time!
