Hi! I am growing 3 plants under a T5 HO 4' (blue) light. Right now they're midway thru budding, with 4-5 weeks to go and I was wondering about supplementing their lighting with some red CFL's on the sides. I've been reading in the forum for about an hour trying to understand more about lighting, but I'm not very mathmatically or electrically inclined. How many CFL's should I get in total - was hoping 4 would do (2 on each side), but maybe I need 6? More? Should I go for the 23 watt (100W) bulbs or the 40 watt (150W) bulbs? Can I put these bulbs on some of those work light cords with reflectors? And how much would this light really help in producing larger, fatter buds in the 4-5 weeks they have left?

Thanks for any advice!
