400w hps in 2x4 tent

So im flowering 4 in 5 gallon pots and decided to throw 2 more in 1 gallon pots you guys think its enough light if so what would i be yielding.

I would have two plants in that size tent with 400 watts, good luck

I agree with beachwalker. You have to many plants in there for your space. I use a 2x4 as well and 3 is the absolute most i can flower at one time and those are smaller plants. But if thats all you have then keep them small or pull some of the slower ones to make room.

Agree. Effective footprint is 3'X3' with a 400. In my own experience.

Several different grows in a 4' x 2' under one 315 cmh. 170 cfm on a 4" x 16" Mountain Air Filter and another 170 cfm intake both on variacs to control the fans. I had in some times 9 plants in 3 gallon fabric pots ad 6 when they were in plastic 7 gallon. They were all mainlined from seed. Some extra work training then if it was a bigger space. The biggest downfall that I found is I could not go longer than 5 days without watering in the 3 gallon fabric pots. In the 7 gallon I could leave them for 7 days if I had to. Good luck @TheAmuck
