I have about 50 eggplants, 50 peppers, and 50 tomatoes under a set of 4 flourescent lights. I plan on keeping them there for the next 2-4 weeks, which is how long it will be before the weather is settled enough to start taking them outside for a week of hardening. I'll probably plant them in the ground the first week of June or so. Last year a late frost wiped out a lot of my plants, so this year I plan on waiting a bit. Question - how long should I keep the lights on? I currently have it on a timer that cycles it
14 hours on, 10 hours off. Or does it really matter?
