You should be able to get 12-15 plants under that light if you overlap them a bit. Works for me, they seem to fight for light more and grow a bit faster

sounds good, do you use a shield or not on the light

A reflector is a must! if you dont you are throwing away more then half of your light. I put better reflectors on mine and they are growing at least twice as fast

alright, the reason i ask is becuase i have an awkward mh light that was used in a warehouse, its shield is glass and its not very wide at all

hmmm id try to put some more reflection behind it. if you dont want to drop 150 bucks on a reflector, do what i do. I got a roll of sheet metal at the hardware store, you know the stuff that is rolled up. I just cut off 12 in chunks, or how ever long need to curve over the light. Then you just have to figure out a way of attaching it to the light. costs about 10 bucks instead

the bigger the better, but if you are planning on growing alot of plants I'd use 2-3 gallon pots, the square shaped ones can be fit closer together
