I have 16 GH Super Bud feminized seeds in my 4x4 tent 10 inches under my air cooled 400w hps in veg.I will NOT be topping or LSTing any. When is the best time (yield wise) to switch to 12/12? I will be using a 1000w air cooled hps for flowering. I am planning on flowering when they are all 10 inches from the dirt. Does this sound about right for a 16 plant in this space? should I veg longer or shorter? Any advide/tips are appreciated. thanks
