couldn't of said it better myself , but with a SOG, your light height is very important. I have never grown a SOG honestly, but i am always aware of heat stress no matter the case. more light generates more heat. if you feel you can get rid of that heat, get as much light, or as many, as you can.i use 1k's, best results with bigger lights. as for per plant, i never did the math. i can fit 40 under a 1k, but i also grow 3' sog plants.
