Been currently growing with T5 in a 2X4X5 tent and cfl side lighting. Looking to maybe step it up a notch and invest in a led for flowering my girls out. I currently have a couple red poision just about done stretching. My actrual "growing space" is about 2X2 because by the time I get the side lights in and a couple of circulation fans, the tent is full. I SCROG to try to keep my height down, but growing in 3 gallon pots, I have just about reached my "workable height" a couple of grows with the T5. I want a light that does a top shelf job of flowering within my 2X2 growing space, but don't want the expense and heat of overkill. I am assuming that the larger the wattage of an led, the more heat output?? I want to strike a balance of max lumens for the least watts. Thanks for all input. I am sure I will get some opinions.
