I would like to ask for any advice from anyone who has knowledge on BHO extraction. I'am using Korean brand that is cheap and it seems like the outcome is really bad. I tried it and it taste different from what I've tasted before. It tastes weird, I can't explain it. My friends says it taste funny. I am thinking of changing the brand I'm using right now but I don't have any idea what is the good one. Any one can give advice will be appreciated.
