How many watt mh hps lights should I use for a 2x2 grow 6 ft tall maby
2x3
I am by far no expert. I run 600w in a 3x3x4. Those aren't exacts. How many plants do you plan on having in that space. I know there's a formula to use but I don't have it and I didn't use it. I flower w the 600w and don't have more than 4 plants at once flowering. I have to keep them short also.
