t5s or t8s doesn't matter as long as its a good setup. I have heard about the light movers and seen them , but that still spreads out over a horizontal space. In order to utilize the space I have, I have to be able to go vertical. So even if I wanted to use MH, I wouldn't be able to utilize the space effectively. I will start looking at the t-5 fixtures, but if they are as pricey as I think they are then I may just use the t-8 fixtures I can get for inexpensive at wal-mart or lowe's. When using a good reflector you can increase lumen produced from the fixture. But unfortunately those are the pricier fixtures. So I guess I will still look and debate. I have more time to think about it. I am just trying to get my ducks in order so I have some ideas. So Thanks Jess!
