I gotta homie up above sacramento area, who has his strains down really well like that. As far as the thick stems, I know alot has to do with the grower and the strain. My friend has been cutting on the same strains for years. Green Crack, Purple Kush and Urkle. All of these have been cuttings that were vegged till 16" or so and he gathered the best phenos and made cuttings with those. Another words, he has worked and minipulated these strains to there full potential(big stalks, roots fast,etc.). My friend has got his shit down so well that when I get the babies at 6inches, they already have like 2-4 heads, not even topped yet. Genes man,genes........O and nice clones.
