Crush the plant material using a stick of clean, untreated wood or any other similar device.
Continue to crush the cannabis, while adding 1/2 cup solvent until the plant material is completely covered and soaked. Stir the mixture for about three minutes. As you stir the mixture, the cannabinoids will begin dissolving off the plant into the solvent.
Strain the solvent mixture into another bucket. At this point, you have stripped the material of about 80% of its THC.
Repeat this process for the second wash. Again add 1/2 cup solvent to the plant material and work for another three minutes to extract the remaining THC.
Strain this new solvent mix into the bucket containing the first mix that was previously separated.
Discard the twice washed plant material.
Pour the solvent mixture through a cheesecloth or fine filter into a clean bowl.
The solvent is highly flammable, so boil the solvent off in a safe environment. A rice cooker is a safe way to do it. And prefferably outside, far away from any sparks or heating elements.
Continue to reduce the liquid until you have roughly 1/2 cup liquid left.
Now combine your sugar and 1/2 cup tincture and mix well.
let this mixture air-dry overnight.
Using a solid object, like a bottle, can or the bottom of a glass, crush up the sugar to remove the lumps.
