That's interesting......I've never heard of freezing trichomes causing harm to their potency; I've made hash with ice water and weed so maybe the problem is in the coconut oil (or clarified butter)and the freezing. I've always kept mine in the fridge until use, but have heard of people freezing them with no ill effect. Just can't comment as I've never tried it myself.

Jebus, I do get some minor bubbling after a few hours but once I get the temp where I want it (about 225F) mine will pretty much stay there alll night so I couldn't really tell you how much it bubbles.......but nothing like a furious boiling or anything. And the room does smell a bit by morning after so many hours of cooking.

Right now we are working on a green dragon recipe that uses glycerine instead of alcohol (vegetable glycerine) The problem is a two month project so it will be awhile before we'll know if that recipe works.
