When making BHO, is it recommended to pop big bubbles of butane by hand? I'd like to end up with a nice shatter consistency, so I'm afraid popping the bubbles agitate the trichomes, causing them to budder up on me. At the same time, I don't have a vac chamber, so my purge setup is a hot water bath placed on top of a griddle. Therefore, the top of the bubbles don't receive as much heat and they often stay that way. What do you guys think?
