I see people commonly say that you need 35-75 watts per sq ft. Is that per sq foot of canopy or total grow space?
I currently have a 600w hps in a 2.5x5 tent (12.5 sq ft) but can only run it at 400w because it gets too hot at the full 600w. My plan is to use this tent for veg and get a 5x5 for flower. I’ll have a canopy about 3x3 or 3.5x3.5 and the reason I want a bigger tent is so
- to make up for the sides of the tent sucking in from the exhaust fan
- I want room around the edges to place my fans/portable ac so I can use the full 600w
- have extra room to work with inside the tent so I’m not having to reach to my back plants as much
Is a 5x5 ok or should I go with a 4x4?
