Yeah The Doc has actually been giving that book away with some orders. If your not a member of HG420 you should join and pm him about the book. They are autographed by BOG himself and they don't seem to be selling very fast. I might grab one too but I grow almost exclusively outdoors. I just enjoy it alot more and to me it's safer. Something about having a huge setup in one of my bedrooms kinda freaks me out.
