well one of my 2 ft flourscent lights burnt out it was a cool white one but now these lights are only used for flowering so should i get a warm white? but i know mixing spectrums is better, i also have 3 cfls and 2 are warm and one is bright white, so my quesion is should i run 2 flourscent warm whites and two warm cfls and one bright cfl or should i run 1 warm flourscent, 1 bright flourscent and 3 warm cfls? what combination would be the best or does it not really matter much? thanks..

cool white is for veg and warm white is for flowering. a equal balence during flowering works quite well. but for veg a mostly cool white would be the best option.

hey man,

there is a really great post, I can't find it now I really wish I had bookmarked it. Either way, it was a post about CFL vs HPS vs Tube Fluro. Anyway let's just say the HPS won hands down, but the CFL came a respectable second. Fluro just got spanked allover the place.

That being said, if you could rebuild everything to run under CFL - that would be better. HPS + corrected for blue spectrum would be best. But let's get to your specific question

Yes, it's true warm fluro spit out a bit more of the red spectrum, but the spectrum range on fluros is already so low on all ends that you will hardly notice any difference at all. If you can replace that busted fluro with CFLs I would do it, and if u could scrap them all and do pure CFL I would recommend that as well. Don't over complicate things that will most likely amount to nothing in your harvest.

Hope that helps!

so your saying this CFL bulb > http://www.homedepot.ca/webapp/wcs/s...e_depot&s=true is better then a regular Fluorescent??? its only 15W and my fluor is 38
