What's my best option?

I just bought a 16ft cargo trailer 7ft wide and just bought 4 of the led g8 900s just looking on some advise on how many plants you would put under the 4 lights with that much space.

I'd say one of those light is good enough for a 4x3-4x4 area. I'd do an 8x7 area in that trailer for flower with those 4 lights. You could grow 16 plants very easily. Then assemble a 4x4 room for veg (hopefully you have more lights for vegging).

Awsome thanks for the advise.

How long would u veg them for from clone. I got a shed for veg then I'm using the trailer for only flower. I'm just trying to get the most out of my plants
