Ok I think I have this right, please let me know if this set up is ok or what i should do to improve it. I want to use Flourecent bulbs only. Ok so im thinking of buying these nice shelves from Home Depot. They are around 86 bucks, very strong and sturdy. HD has T12 light fixtures in which im told I can place T8 bulbs into. The fixture is 8 dollars and some change. The shelves are 4 feet wide so on 4 shelves i can place 4 trays each to start seeds. That's 48 plants per tray times 16 trays. Thats 700+ flowers on one shelf unit. Now if I have this right I have to place under each shelf 2 light fixtures for a total of 4 bulbs making it 8 fixtures per unit and 16 bulbs total per unit. What im hoping for is that this set up is good enough and that the plants will grow with these lights, or can I get away with one light fixture per shelf? ( I DOUBT ). I'm actually thinking of making 2 shelf units like this for over 1400+ flowers. please comment thank you
