After 45 minutes, remove the glass jar from the oil bath and let it sit for a few minutes to cool down. Then, place your fine mesh strainer on top of a clean glass jar, and dump the cannabis/VG mixture into the strainer. You’ll need to use the flexible rubber spatula to press/squeeze out the liquid from the clumped-up buds, through the strainer, and into the clean jar.
Once you’ve got this first run squeezed out as much as you can, put those same cannabis buds back into a glass jar, adding more VG to repeat the process (all in all, you will be doing three runs total, repeating steps 2-7 . *And on a side note, that “first run” will by far be your most potent THC liquid, so you can either leave this separated for a super-strong vape juice, or you can add runs 2 and 3 to it to increase your total volume. After you’ve repeated steps 2-7 an additional two times (adding fresh VG and making sure to maintain your key temperatures both times), you’ll need to further refine your VG mixture with cheesecloth to filter out any remaining plant debris. Clean off your mesh strainer, and lay about four layers of cheesecloth on top of it. Pour the VG mixture onto the cheesecloth, letting it drip down into the clean glass jar as much as it can. Use the rubber spatula to squeeze as much liquid out as possible (you can even use your hands to squeeze out any remaining liquid that you can’t get with the spatula). After you’ve filtered all of the liquid through the cheesecloth, you’ll want to boil the refined THC liquid in your oil bath at 220℉ for about 30 minutes to fully decarboxylate the THCA into THC (you’ll have to increase the temperature of the “outer” oil bath in order to get the temp of the “inner” glass jar to 220℉). Watch out for the liquid to start bubbling (giving off carbon bubbles), and be careful not to go much above 220℉ as this will cause the THCA to convert into CBN). If everything has been done correctly, you should be left with a potent, clean, debris-free VG liquid that’s infused with THC extract, at which point you can use a syringe or dropper bottle to add to your vape cartridge and begin vaping. (For maximum effect and taste, allow about 15-20 minutes after you add the THC e-juice to the vape cartridge before you begin vaping.
This allows the wick to fully absorb the e-liquid). THC Oil for E-cigs: Method #3 – Rosin Extraction (Mixed in with Vape Solution) As we mentioned earlier, this is our preferred method to make THC oil for vape pens because it’s the highest quality, most potent, most flavorful, and (perhaps) even the safest because it doesn’t use any thinning agents. Also, it’s quicker than both of the other methods and you can use already-made THC concentrates (such as shatter or BHO wax) if you don’t have the tools to press your own rosin! If you do want to start from raw nugs and press your own rosin, however, you will probably have to purchase some special products that you are unlikely to already have. Here’s what you’ll need: Some dry herb (has to be dense nugs, ground-up buds will not work) Hair straightener Parchment paper Small glass vial for mixing 1 g bottle of The Potion Natural Terpene Solution Lighter Vape pen cartridge syringe (for adding the THC e-liquid to your e-cig) Mixing wand Dropper bottle (for adding The Terpene Potion to the glass vial) Basically, this method involves using a hair straightener to press rosin from a raw marijuana nugget, collecting the rosin off of the parchment paper, adding in a few drops of The Potion Terpene Solution, and heating it up to mix it together. A little tricky if you’ve never done it before, but like we said – the most potent, highest quality, and best tasting of the three different methods. Here are the steps: Select a good, dense nug to use for pressing out the resin. This is a crucial step, as it’s imperative that the nug be dense and tightly-packed with almost no seeds or stems . To obtain enough e-liquid to use in your e-cig or vape pen, you’ll probably need to end up using about 3g of fresh buds (or right around an ⅛ oz). Either way, your goal is to get about 0.4g-0.6g of rosin. You will probably have to press several different buds separately in order to get this much. Once you’ve got your densely packed, high-quality nugs, get your hair straightener ready. A good temperature to press rosin from nugs is about 250-280℉, so if you know what temperature your hair straightener is operating at, you can adjust accordingly. (If the minimum setting is a higher temp than this, you can let it get hot, then unplug it and let it sit for several seconds to cool down and try and get into that 250-280℉ range). As we said, a lot of this method is trial and error – especially if this is your first time doing it. Set the nug on a good-sized piece of parchment paper, and fold the paper over the top so the nug is sandwiched between. Then, once the hair straightener is up to temperature, put the rosin paper in the straightener and press down with as much force as you can for several seconds, careful not to burn the nug (or the paper). If done correctly, you will be left with a small amount of resin on the parchment paper that you can later peel off. Repeat steps 2-3 with fresh nugs and fresh parchment paper until you’ve gone through about 3 grams of dry herb. Like we said, you’ll need at least about 0.4g of rosin to get a decent amount of e-liquid for vaping. (You can use less than this, but it won’t be as potent). Once you’ve got about 3g of buds pressed into rosin, you’ll need to collect the rosin off the parchment paper. It’s best if you stick it in the refrigerator for a minute or two, as this helps it peel off the paper easier. Also, don’t touch it with your hands – we like to use the ball end of a metal dabbing wand to kind of “roll it” it off the paper into one big ball. Once you’ve got about 0.4-0.6g of rosin collected, put all of it into your small glass vial. Next, use a dropper bottle to add 8 drops of The Potion Terpene Solution to the vial (use 8 drops for approximately 0.5g of rosin).
Once you’ve got the rosin and The Potion in the vial together, use a lighter to “flash heat” the glass, just until the liquid starts to bubble (this only takes about 3-4 seconds). Be very careful with this step, because if you let the solution get too hot, you’ll burn off all the terpenes and kill the flavor of the e-juice (not to mention risk burning the THC rosin itself). Immediately after The Potion liquid starts bubbling, use your skinny metal dab wand or mixing wand to mix the solution up thoroughly.
Then, use your syringe to suck out the liquid and add it to your e-cig or vape pen.
