I've read thru posts and looked at pictures and can't seem to find a definite answer.
I recently bought one of those wire shelving units from Sam's. It works great and I have 4 flats on 2 of the shelves. I have 3 of the Home Depot shop lights on each shelf. I'm new to this and wondering if the lights need to be directly over all the plants? The flats stick out a little on the front and back so they are not directly under the lights in those areas but of course some of the light spills over. I try to not use the full amount of the tray so that there are very few that are not right under the lights. Should I move those plants on the end to another shelf with another light or is it ok the way it is? I see some people look like they only have 2 lights on those same shelves in some of the light setup pictures but I can't be sure.
Either way, I will need to be picking up another light soon as I've been transplanting like crazy and they won't all fit. I bought the box of Philips cool white but I'm wondering if with the next box I should go with the daylight deluxe and mix them in with the cool whites? Do they make a big difference for the price?
