I would stop boiling it now. (-:ive read a couple different things, to boil it for 24 hours, and to do it for an hour. ive alsoread boiling for 24 hours makes it bitter too. i mixed 2 cups water with a 1/4 oz of very potent nug and a stick and half of butter for one dozen batch of brownies.
how long would you guys recommend boiling for, ill do it for a couple hours probly if i dont get any help.
