im limited on room as well and also flowering. I figure if i hang the T5 to light the back of her with the hps on the tops it'll probly be good. I think the 2' only put out like 8,000 lumensI use (2) 4 foot 4 Lamp T5s in veg for my babies, and I love em. I do have (2) 3000 and (2) 6500 in each lamp as well. Seem to grow like crazy with em... at least for me.
They do put out a bit of heat though which I wasn't expecting or did think of, so had to induce some cool air to room to compensate.
Ya for veg im sure they're fine. It'll probly prolong the flowering processi use only 2' t5 for veg and they work great. i have 3 lights, 2 are 4 bulb and 1 is 8 bulb, the strange thing is the 4 bulb use .8 amps while the 8 bulb uses 2.3 amps.
