I'm letting this one grow naturally, no training or topping, as I tried that before with FastBuds strains and none of them ever reached the height stated on their website (lucky me I guess). It is branching and budding nicely, and has a good structure. I use LST, SCRoG and defoliation on my photoperiod strains, but to me it seems a bit pointless for autos that are this short, but I'm happy to be educated.
