Is 8 hours under lights enough?
I have a 3-tier plant stand with 2 t5 lights on each level. I have been leaving the lights on 24/7 and running two "shifts" of plants - each flat getting 12 hours on, 12 hours off. Now I'm wondering whether I could get 3 shifts in, 8 hours on, 16 hours off. (I have seedlings in flats that should be separated and potted up.) I know it's not ideal but with the fairly high intensity of light, do you think it might be okay for the next month or so? I'm growing mostly tomatoes, peppers, eggplants, leeks.
