Hey Faith..

if you are using the CFLs as side lighting then tall is ok and you actually might have some amazing results.. but it will take some care and precision.. cause 250 watts hps will not give you more than 12 inches of decent penetration..

I would go with 3 - 125 watt CFLs, keep them very very close to the sides of your plants..

Garden Knowm Reviewed by Garden Knowm on . 5 Small Or One Big CFL? . I'm moving into 2 * 2 meters, so I'm filling out my 250HPS with about 100 watts of CFL. I can get 6 * 20w CFL's for just a little cheaper than 1 * 120w CFL. Of course I have to do all the wiring, but would small ones be a smarter pick, as I can sort of "laser" guide them better ? Or just go with the 120w CLS and fill the room with lumens? . Rating: 5
