Hello fellow farmers! I have been reading these forums for a couple years now, and they have taught me an immeasurable wealth of information in every possible part of cultivating/smoking/processing the marijuana plant, so i have to start off by just saying thank you to all the people on these forums. I have been on many, many MJ forums like gc, tc, etc, and i have to say this one seems to be filled with the most knowledgeable and helpful people that don't hesitate to help everyone out. Thanks for everything~ Ok, now that i've got that out of the way, I have a question for all you errl lovers. What is your preferred method of purging your BHO? i've watched countless videos and read waaayyy too many posts on the topic, but i can't seem to get a consistant, clear answer as to the best way to purge your BHO. But i've narrowed it down to 3 techniques that seem to be used the most, and i've personally tried 2 of them many times (i'm going out to buy a mityvac today to try the 3rd) and i just want to see what this community thinks is the best method. The first is the standard, HmK's amazing tutorial method, after the initial hot water bath purge, bring the dish inside and double boil it with a lid loosely covering it on about half heat on the stove, use a torch to pop big bubbles as long as they flame up when they pop, about 30 minutes-1hr of this for 1-2 grams of oil. The only question i have about this is, would it be safe at this point to put the double boil on a stove without a flameless heating element? or am i gonna blow myself up? The second is another highly recommended method, which is to spread the bho evenly across the bottom of the dish and put the dish on a flameless heat source on low to medium heat for 4+ hours/overnight and check to see that the bubbles stop rising. I am just curious as to whether all the extra time is necessary, and i feel like this method destroys a lot of the terpenes. The third is to first do an initial purge via the Hashmasta-Kut tutorial, then scrape your oil onto parchment paper, put it in vacuum chamber on some sort of low heat source to force viscosity, and get it to -25hg for about 10 minutes, re-pressurize and repeat. I'm going to buy a mityvac later today to try this one out. if you have another method, please, post it! i'm all ears.
