recommended grow books

I just finished reading Ed Rosenthal's Marijuana Grower's handbook.. pretty good read, although 85% of it i already read on here.. however it cleared alot of things up for me that i wasnt sure of and gave me tons of new tips.. ive been looking for "marijuana botany" but cant find it anywhere.. is there any books I can purchase that discusses more advanced areas of growing?

nevermind i just checked similar threads and seen a number of these.. i think im going to check out Marijuana Horticulture im still open to suggestions.. i want something explaining more advanced techniques such as breeding, cloning, etc
