i dont have alot of experiance with cfls i did use them with my t5s tho for lower lighting in my firsrt bag seed run and they did help..imo they wud do fine....they do branch alot so just put a light over each top and u'd probly be fine...let us know how it goes!!I'm gonna try some of these out, just got my seeds last week. For now, I'm just putting three in my veg area, which has a fairly low amount of light. I have 2 105 watt CFL's, plus a bunch of other 40 watt fluorescents. I would put em upstairs under my 400 w hps, but I don't have room, and I'm jst looking to make seeds with this round. do you think a few good sized cfl's would be enough to get some seedy bud? Your plants look amazing, man. Hopefully I can get mine to look that great next round.
