First time grower question. I have a 3x3x6 grow room with a 400 hps light, how many plants can i squeeze in with this light or should i get a bigger light?? Thanks in advance for any help.:rasta:

The rule of thumb for container plants is 1 square foot for every plant minimum. You either have 9 square feet or 18 square feet. Depends on which number is height. Either way with a 400 I would run 4 to 5 normal sized plants. 2 to 3 SCRoG plants and maybe 20 SOG plants. Any more and you'll outgrow what the the light can handle.
