Hi! So I've been yoking for a few years but I'm currently on a month long break due to a life insurance drug test :/ but I decided to make some bho to break my miserable 30 days of sobriety, It's a tiny run using about 2 grams, just cuz I didn't want to waste a bunch of my herb not knowing how it would turn out. I made the extractor from plumbing parts and did it in a garage with a huge fan and tons of ventilation, the results where pretty surprising, I got a nice little sheet, prolly about .2 of a gram and I am so excited for the test to be over. Let me know any tips you guys have on how to get a higher yield or anything really, thanks for looking! I'm trying to upload pics but I'll have to do it from my PC later
Stainless steel or glass extractors are the way to go. Other materials can react with the butane and strip contaminants into your oil.
