no, no heat in BHO, you can whip (coffee warmers work good) it but not really heat it. making a pure extraction is not like making green dragon or Butter for cooking. Heat is not need to to extract a pure product. The process of making pure weather in BHO or Ice-O-Lator is similar in that they freeze the bud making the tircomes brittles and manageable and able to handle.

NO heat MORE cold in making pure
MadSativa Reviewed by MadSativa on . Heat Cannabis before butane extraction? This question is most likely already answered but i just want to make sure im up on my chemistry. I have seen many a video and many a thread demonstrating butane extraction, but ive seen none that say anything about heating the cannabis before starting the process of extraction. I know that canabis must be heated to convert the pre-THC molecules to activated THC as one would with green dragon or canna-butter. Is there some reason why this isnt necessary with the butane method of Rating: 5
