Same as our CannaOil recipe, first you have to follow the decarboxylation recipe listed below.
Preheat oven to 240˚F.
Grind cannabis using a hand grinder.
Spread ground flower evenly on a cookie sheet and bake for one hour on the middle rack, stirring after 30 minutes.
Divide the decarboxylated cannabis evenly into your mason jars. Add half of the cannabis oil to each jar and seal as tightly as possible with the lid.
Place mason jars in your slow cooker and cover with boiling water so that the jars are fully submerged. Set slow cooker to low or warm and let cook for 4–5 hours. Using a jar clamp or heavy oven mitts, pull the jars out every 60 minutes and give them a good shake.
