Hey
Ed and your friend are full of shit, bubble hash is the worst thing you could make. If you are sensative the taste/coughing may not be avoidable but in my experience BHO does the best job of killing off the mold/mildew. If you are going to do the bubble bags let the bad bud sit in the ice water for at least an hour, this seems to kill off or freeze the nastiness so it doesn't kick you in the face when you smoke it. I've made bubble hash rather quickly and it seemed like I just concentrated the powdery mildew. I'm sure your amigo's are trying to help, and so am I. Take care, avoiding the mold in the 1st place is the way to go. Look around and find the culprit. I've had my fans hooked into the timer with my lights and grew a helluva batch of pm, keep fans on 24 hrs. Hope this helps, no offense to ED and your friend
