im using buds and 99% iso. winterize both in the freezer 24 hrs. strain twice through coffee filters. cook it off on pyrex pie plate and electric frying pan. what temps does everyone use to finish cooking iso off and does it make any difference to quality if no heat is used but instead a fan blowing over plate till its done. im smoking this oil to get high....not for meds. all techniques are welcome. what do you all do?
