yeah man ive done that same thing, my brother started doing that like 8 years ago, so when i started smoking weed i bought a electric bud buster(coffee grinder) and make hash, but i just let my thc build up in the budbuster, so when ever i want a joint a bud bust it an leave the ectra crystals in there till it can make me a nice huge nug.. an by the way for you people wanting to try this... its so easy to do, but if you fuck up u can lose alot of thc!!!
