if im gonna have a MH/HPS 400w setup, and i swap between them through the stages. how many plants could i grow at once?
I'd say anywhere from 2-6. I've got 4 under a 400W HPS right now and there's really no extra room for another plant. I did top all the plants to make them more bushy.

If you dont plan on topping/LST'ing/FIMMING, I would say 6-8 plants
