dude, i use everything from my grows, nothing is wasted, Male plants, stems, fans, female sugar trim and popcorn buds all well dried, crushed, and broken into small pieces. this is the recipe that i always follow.
3 cups of above plant material.
3 cups water
2 sticks of butter = 1/2 lb.
Boil water
Add butter
Add weed
Stir it up
Let boil 1 to 2 hours.
Stir occasionally.
When alot of the water has evaporated off but there is still some left pour it all through a strainer into a big bowl.
Then strain and squeeze the cooked weed through cheese cloth or another type strainer catching all the liquid in a tall plastic container.
When you have squeezed all the moisture you can out of the weed, you may then discard it or find another use for it.
Cover the tall plastic container and place in the freezer.
When frozen, remove the contents.
You will see the butter and the frozen sludge water have seperated.
Cut the frozen sludge away from the butter and throw it away. This contains lots of plant material and grit which many find offensive to taste and digestion.
You will see the reason for using a tall container instead of a bowl to freeze the butter in was to make seperating it from the sludge much easier.
So now you are left with one fine slab of pure cannabutter.
Keep it frozen until needed.
Then slowly thaw and use in place of oil for making cookies, brownies, whatever. If you squeezed it well you will have right around 1/2 cup
not my recipe originally, but its the one i use.
