I havent tried my own extraction yet? Ive read quides on the internet about it but it looks pritty complicated I understand useing isopropic alcohol and shaking in a jar, then letting the liquid sit until its evaporated, but what then do you do with the black tar And how do you tell how strong your extracts are??? 10X-20X You can get a pound of leafs off bouncing bear for $100! Thats like 450 grams i think? Enough to make 22.5 grams of 20X.
