Adding CFLs

ok im growing inside a pc case that u can find in my sig... im considering adding (2) 13 watt OR (2) 20 watt CFLs. im not sure if it will fit but if it does would it be worth adding? would it increase my yeild at all? any help would be great thanks

Why not add another 42?

becuz i really doubt that there is enough room in there for another 42

ur def gonna need some more lighting.. the more the merrier..dont get me wrong ur shit is sweet

thanks i love it.. like the lights are doing great i just wanted to see if it would increase my yield significantly
