more LUMENS per sq foot is better. watt is the rate of energy conversion. lumens is the a measure of the preceived power of light.

you want a minimum of 5,000 lumens per sq foot. the more the better!

if you already have the UFO then why not use it. it can be done. and definitely supplement with CFLs. like macro said, 6500K for veg, 2700K for flower.

you should start a grow log too!

headshake Reviewed by headshake on . LED with CFL's??? I have a 90W LED UFO and was thinking of adding a couple CFL's. Is it at good idea to do that? I know the more watts the better but was wondering about the different spectrems. Please recommend what CFL's are best. Advise would be much appreciated. Rating: 5
