how can you make hash and butter out of fan leaves and stems? it doesn't sound reasonable to me.
Reasonable doesn't have anything to do withit.
Leaves still have essential oils (aka the shiot that fucks you up) Just not in quantity
If they arn't frosty get some iso alcohol (highest % possible) to make some cheap cooking hash (earwax is made this way generally for all you club goers)
I would recommend making hash before you make any edibles because with low potency leaf you never really know how strong the end product will be.
If you use hash oil atleast you can semi approximate without a test run.
Edit- after thc extraction I think you should try to compost that shit.
