I put up trellis at end of week 3 and they started to fill out the trellis in under a week. I've been feeding them relatively heavy on the nutrients for a sativa but they love it! I was waiting for these plants to flower on their own, thinking my last grow got a dud auto seed. All 3 seeds I got ended up working like a photoperiod. No complaints from me though as I prefer photos to autos.
