I have a 10-ft x 10 ft gross tent, with just five plants right now. My question is what kind of light setup should I have I feel like I’ll need a new one because right now I have the vivosun AW200SE with fan.

Welcome to our Forum.
I’m kinda surprised you don’t have any recommendations yet. These guys all seem to know their lights pretty well. I have some notes but you’d likely not be able to read them. It all is going to depend on how much usable light reaches your canopy. Anyway, from what I gather most manufacturers inflate their numbers to get sales and without all the scientific equipment you really can’t make a determination on your own. So I just use that little 2 prong light meter and make sure all the tops of my plants show in the green. I guess with a 10x10 you would maybe have to see about getting 2 lights so you’d have more room to make adjustments to each. I know none of this is helping, but hey… I tried.
If you utilized the whole footprint, you would need about 4,000 watts. Or if you do it by plant, about 1,000 watts. Typical watts per sq. ft is 35-40 and watts per plant is about 150-200.
As for set up, I would buy 1 main light and 1-2 supplemental smaller ones you can raise and lower for plants at different stages.
