For the Green Dragon method, place the decarbed cannabis at the bottom of a pint-sized mason jar. You do not need to grind the cannabis.
BEFORE you pour the alcohol over the cannabis, know that you only need to add enough alcohol to cover the plant matter completely. Cover the cannabis in alcohol, add the lid to the mason jar, screw the cap tightly and shake gently.
Place the mason jar in a cool, dark location like a cupboard or closet and leave to sit for 24-hours to 30-days, as desired.
After your desired soak time, remove the lid and strain the tincture through a coffee filter or cheesecloth into a clean mason jar, separating the plant matter from the alcohol.
Place the strained tincture mason jar in the bottom of the mini-crockpot. Carefully pour water into the crockpot, BUT around the jar, creating a water bath. Turn the mini-crock pot on warm and allow the water to heat up.
Make sure you do not have the lid on the jar, as this will halt the evaporation process. Additionally, I recommend doing this in a room with good ventilation to keep the windows open and airflow moving.
The time it takes to evaporate all of the alcohol will depend on the starting volume of your tincture. More tincture will take longer, and less will be shorter. For example, 1 cup of tincture will take approximately 4-5 hours to evaporate down into FECO, where a ½ cup of tincture will take approximatley 2-3 hours or less.
The alcohol will evaporate during the cooking process, reducing the volume of the tincture significantly. This is normal. You will be left with a small amount of a thick, black, sticky substance. This black oil is your FECO medicine.
If this black oil gets too sticky or hard to work with, add a few drops of alcohol or carrier oil to the jar and mix well to create a more viscous oil.
Store your FECO in a glass syringe, capsule, or another airtight glass container. Store in a cool, dark place like a medicine cabinet. Be sure to dose appropriatley, as FECO can be very potent.
Amounts: You do not need to use the full 14 grams of cannabis called for in this recipe. You can use as much or as little cannabis as you want. Just understand that your yield will be very small, as little as 1mL, and dependent on how much cannabis you start with. You also do not need to use the full 8 ounces of alcohol, you just need enough to cover all of the cannabis in the container you are using. Anything more is a waste.Alcohol: Only use high-proof alcohol; the higher, the better. Lower-proof alcohol, like vodka, is not ideal. Use this guide to find high-proof alcohol, if needed.Soak Times: I’ve seen traditional, long-soak tinctures steep anywhere between a few hours to up to 6 months, or longer, in some cases. Soaking your plant material for longer will slightlyincrease the potency but will also increase the amount of chlorophyll and plant matter in your final infusion.Evaporation Options: If you want alternative options for evaporation, follow this guide on how to evaporate the alcohol safely.
