Hmmm... How cold is your freezer? Vovin's Tek recommends around -20C or -4F.Xtal said:Ughhh... yet again, the third and fourth pulls have yielded NOTHING. Nada, zip, nil, squat. Not even a crappy crystal of DMT oxide. What am I doing wrong? I left all the naptha from the pulls to freeze precipitate for more than 12 hours, then nothing. I'm sure that at least I haven't screwed on on the tek... everything seemed to go in order... could it be the bark?
