My summer buds are never as tight and dense as the winter time. I usually harvest my last crop by mid June (July 5th this year) get my room cleaned, updated, plant new seeds for new winter strains and start flowering again by late August. The 2 month break from flowering keeps me sane, I don't get burned out anymore and there's enough to do in that time anyway because I still keep my veg room going.
I've grown out several white widows from different breeders (GHS, Nirvana, Ceres, White Label and a few clones from other patients) and they were all different. Might as well have been different strains because it seems like every breeder has a WW.
