[KamelRedLight]

Cyric I'm not sure yet. This is news to me too and I'm working on finding out if daylights can flower as good or better than soft whites. I replaced 42w, 2700 lumens of 2700k light with 2x26w, 3200 lumens total of daylight. It's a little more light, but not that much so I think if I find a difference in yield it'll be safe to say the spectrum was involved. Again, there's no control group in this test, but based on past clones, the size of this plant should yield less than a 1/2 oz. if flowered under 2700k light like I have been doing. So I think it's fair to say if I get over 14g, the daylight helped.

I was gonna do a comparison like that Vtec but my other clone won't root. It sucks having so little space to work in. So many experiments I wanna do. Learning is fun!

Thanks Zarathustra, but I wouldn't bet on this just yet. This idea is pretty much completely going against accepted common knowledge about the flowering stage requiring a red spectrum. Grow shops advertise HPS lights or red spec CFL's as flowering lights. The blue daylight spectrum has previously only been for vegging to most people, including me. I've gotta wait to produce some hard results before I can be sure of this. As for that light though, I've never used a huge CFL like that, so I can't speak from experience. I would expect you'd get a damn good product for that money, but I wouldn't really want one. I grow with CFL's mostly to keep my wattage low. That's why I'm so obsessed with maximizing the spectrum. I'd sooner get a 250w HID light than a 200w CFL, more light per watt. But to choose between 3 65w lights and 1 200w light, I'd take the 65s. You can get em cheap and local (if you're near a wal mart which I'm pretty sure everyone in America is) so if they ever break, just get a new one. Plus, your light is more spread out for even distribution. That's my thoughts.

Thanks again for readin, and if anyone's willing to do a 6500k flowering vs 2700k flowering test, or has, by all means do share.
