I'll start by saying this is my first time growing. I have 2 White Widows and 1 Amnesia Haze, all 3 are autos in peat pellets. I was confident until they poked their heads out of the dirt yesterday, and now the questions are setting in. Growing in a 4x4 tent. Right now I have 2- 75 watt CFLs about 6" above the starts, but I do have a 275w Vivosun LED ready if I need it. When do I set up a screen to ScrOG, and how high should it be? Do I make 2x2 squares? I have a million more questions, but this is a good start.
