hi ya:jointsmile: im pretty new to tgrowing myself, just started last month using cfls. yes u can grow under small amount of light but will take ages and the yield will be crap if ne.
start of with at least 50w of light for few weeks as young plants dont need excessiv light. than once bigger u would need to add more around top and around sides, if this is not poss than maybe consider new grow space.
Try to hav at least 125w or more once flowering comes around.
light spec
vegg: 6000k
flower:2400K

hope this helps, good luk
jkeabs Reviewed by jkeabs on . CFL Light help! gonna start growing in a locker, so the plant won't be big. Issue is i can only fit one, MAYBE two 23 W CFL's in there. Mind you that there will only be one plant in there at a time. The lockers are roughly 2 feet tall, but i will probably LST them or trim them to keep them smaller. Is one 23 watt CFL good for one plant? Or should i try and fit more in. It will be possible for me to fit two, although it might take a little fidgeting XD. thanks for your help Rating: 5
