What Is Epsom Salt And Why Is It So Important For My Cannabis Garden?

There are many different ways to modify your garden into a more organic, natural environment for your cannabis plants to live in. Using natural ingredients is one way to ensure the best quality plants, and luckily for you, there are plenty of natural sources for your plants to get all the nutrients they need. Here, we will be looking at Epsom salt for cannabis growth and what it can do to benefit your growing ambitions.

Origins Of Epsom Salt

Epsom salt, the nickname given to magnesium sulfate, is a compound that was discovered in underground springs in the town of Epsom, England. It is a natural and organic source of both magnesium and sulfur. Epsom salts are commonly used in bath salts, exfoliants, muscle relaxers and pain relievers. However, these are different from Epsom salts that are used for gardening, as they contain aromas and perfumes not suitable for plants.

Why Should I Use Epsom Salt For Cannabis?

Using Epsom salt for cannabis plants is extremely important for those who want to begin implementing more organic ingredients in their gardening habits. When using Epsom salt for weed, it’s almost impossible to overfeed your plants. At the same time, it provides them with a healthy dose of micronutrients that are crucial for strengthening their cell strength and overall immunity.

A Natural Source Of Nutrients

Epsom salt is an excellent addition to your gardening routine, as it’s a natural source of two of the most important nutrients for cannabis plants: magnesium and sulfur. Using Epsom salt for cannabis will allow a gardener to rely less on synthetic nutrient supplements or specialized, fertilized soils. Adding organic ingredients like Epsom salt to the diet of your cannabis plants will therefore ensure healthy soil and a healthy lifecycle.

The Importance Of Magnesium in Epsom Salt

Epsom salt is a natural source of magnesium – one of the most important nutrients to a plant’s life, as it encourages its uptake of essential nutrients like nitrogen, phosphorus and potassium. Magnesium is also important for your plant’s development of chlorophyll, the component responsible for your cannabis’ ability to absorb sunlight, which allows photosynthesis to occur by strengthening cell membranes. Overall, a healthy level of magnesium is what’s responsible for the successful and healthy growth of your cannabis plants.

Why Do Plants Need Sulfur?

Sulfur is the essential basis for your plant’s immune system. Sulfur facilitates the production of amino acids, enzymes and vitamins in your plant, all of which aid in the healthy growth of a plant and build up its immune system. In other words, a healthy base of sulfur in your garden will help prevent your plants from getting sick. Sulfur is also essential for your plants to create chlorophyll. Most importantly, it works together with magnesium to secure the plant’s uptake of nitrogen, phosphorus and potassium, or NPK – the most essential nutrients to a cannabis plant’s survival.

Bring Epsom Salts Into Your Garden To Prevent Deficiencies

Now that we know why magnesium sulfate, or Epsom salts, are so beneficial to plant health, we can apply this knowledge to our own marijuana grow ops. Using Epsom salt for cannabis gardens is an excellent way to prevent or treat magnesium deficiencies that will negatively impact bud growth, or sulfur deficiency, which can harm plant growth and cause discoloration.

The Right Time To Incorporate Epsom Salt

You can begin using Epsom salt for cannabis plants within the beginning of each lifecycle, when the plants are just a few inches tall. You should, however, cease using Epsom salts during the first week of flowering, as this can alter the growth of buds. Generally, a good amount of magnesium and sulfur throughout a plant’s life will ensure a high yield.

How Much Epsom Salt To Apply And How?

The ideal amount of Epsom salt for cannabis plants is one tablespoon per 5 liters (1.3 gallons) of water, or about one teaspoon per 3.7 liters (1 gallon) of soil. You can use Epsom salt for weed growth as a topical foliar spray when diluted with water, or incorporate Epsom salts directly into the soil or substrate. It’s a great way to prevent or treat magnesium or sulfur deficiency.

Start Using Epsom Salt Now

Epsom salt is an excellent way to ensure proper nutrient levels in your garden by using natural sources for organic ingredients. As proper levels of magnesium and sulfur are critical to healthy cannabis plants, using Epsom salt for cannabis can be considered a necessary addition to your gardening shed. Whether you want to start a new substrate or are looking for a natural way to cure some nutrient deficiency, Epsom salt and marijuana makes for the perfect team.

For soil growers who wish to grow organically or who cannot afford (or don’t want to buy) professionally blended supplements here are a couple of methods to cheaply and effectively supply your plants with all the calcium and magnesium they need.

Calcium is one of several key nutrients necessary to grow healthy plants indoors.

Instead of applying a commercial fertilizer that contains calcium carbonate a common way of infusing plants with this needed nutrient, you can use eggshells to do to the same job much more cheaply.

Adding crushed eggshells to your indoor plants is a natural way of providing them with extra calcium, because eggshells contain more than 90 percent calcium carbonate.

How to properly prepare and apply eggshells so your plant gets the most benefit out of them:

1. Collect discarded eggshells in a bucket.

2. Thoroughly spray the shells with warm water to clean off any remaining protein from the inside of the egg. Remove as much of this organic debris as possible to reduce any chance of smell or unwanted pests.

3. Allow the shells to dry overnight.

4. Place the dried eggshells into a blender or food processor and grate the shells into a coarse powder. Personally I crush the dried eggshells into tiny pieces and grind them to powder in a mortar and pestle I bought at Nam-Hai On 21st just East of Garnett in Tulsa.

5. Blend the eggshell powder into your growing media. There are no hard and fast rules that I know of concerning how much shell powder to add but I’ve found 1/4- 1/2 of a cup per gallon works wonders and doesn’t lower the soil PH too much.

6. Alternatively if your plants are already growing pour the powdered shells directly onto the soil around the base of the plants that you want to fertilize.

7. Water the plants to absorb the powder into the soil.

Warning:
For best results, only add eggshells to your indoor plants about once per growing cycle. Adding the shells too frequently can reduce the pH of the soil to unsafe levels for the plants.

Magnesium is another nutrient your plants absolutely must have edequate amounts of in order to grow and produce well.

Magnesium is important to plant growth from seed germination to photosynthesis to flowering. The National Gardening Association (Not talking about marijuana!) indicates magnesium strengthens cell walls and improves uptake of nitrogen, phosphorous and sulfur.

In fact magnesium deficiency is one of the more common killers in homegrown marijuana!

Fortunately if diagnosed in time this is an easy and cheap fix you can pick up at any Wal-Mart for very little money. Epsom Salt!

Epsom salt is the best and most natural way of adding magnesium and sulfur to your cannabis plants. The benefits are astounding and there is little risk of overfeeding. Epsom salt is the nickname given to magnesium sulfate. The name originally comes from the spring water of Epsom, England. Farmers were quick to discover that Epsom water had “magical” healing properties and its fame quickly traveled far and wide.

Epsom salt is a fantastic and completely natural way to give your cannabis plant an extra boost of both magnesium and sulfur with the added benefit that you really can’t go very wrong with it.

Excess feeding of these micronutrients will not have a negative effect on your plants. It is almost impossible to oversaturate the soil over time. Epsom salts also can be used in hydroponic systems; though here, you should be particularly mindful of potential PH swings.

Epsom salt is a valuable source of magnesium. Chemically known as magnesium sulfate, Epsom salt is 10 percent magnesium and 13 percent sulfur, both important nutritional elements for healthy plant growth. Epsom salt is neutral in pH value and has no effect on soil pH levels when applied to soil in dry application or as a drench.

Application:
If you blend your own growing media add roughly 1/4-1/2 teaspoon per gallon of growing media. Since I also use an Epsom Salt foliar spray throughout the growing cycle I blend the lower level of 1/4 teaspoon per gallon into my growing media.

A foliar spray made with 1 tablespoon of Epsom salts in 1 gallon of water can be applied to plants showing signs of magnesium deficiency. For healthy plants plants 1 teaspoon per gallon is fine. Epsom salt spray can damage foliage when applied during hot sunny weather so if you’re growing outdoors spray late in the evening, If you’re growing indoors under Metal Halide or HPS spray just before your off/night cycle. If you’re growing under fluorescent tubes or LED you shouldn’t have any trouble with leaf burning.

Signs of Magnesium Deficiency
The deficiency can occur for 4-6 weeks before any symptoms appear.

Here is a list of some of the more common signs:
Yellowing outside the veins of the marijuana leaf.
Brown spots appear on older leaves.
Leaves have a pale green color.
Old leaves curl, dry and start to fall off.
Plant looks sick overall
Drooping appearance.
Tips of leaves may appear slightly burned.
Marijuana leaves curling down.
