Hi all, I picked up three 3' 39w T5HO light fixtures. The can be piggybacked and I was considering mounting them to a piece of 2"x6"x12" wood and suspending it above my plants. There is a reflecter for them that snaps into the fixture, so my mounting would not change after they arrive. I am thinking of having 2 fixtures, one 3 bulb, an one 2 bulb for flexibility. Any feedback is appreciated...
