Seems that no matter how long I vape the MFLB, I can't get the right timing down on vaping the weed. Like, whenever I read on GC people say the bud should turn brownish. However, mine always goes from green to blackish. If I don't vape till it starts turning blackish, I only get like 3 hits? I tried making the bud really powdery, in the middle, and dense. I'm lost. It's not ash, but starts getting black and some brown buds. Is this normal? I'll put a picture up when I get home from work!
