4ft floros? Should I buy?

[ClarkNewbury]

the color temp of the bulbs you purchase is really up to what you need them for...

So tell me.. I'm five weeks into flowering, I currently have six 23w, 1650lu warm bulbs on two plants. Should I buy cool bulbs or more warm? Flowering likes warm but I don't have any cool at all..

The way I see it is that plants enjoy all healthy light, but certain light promotes flowering, and certain light promotes other production... I keep a variety of lighting and have just come to consider it best practice.

Well, I suspect the cool put off more lumins, and there is a lot of veg still on the healthy flowering plant. (Reg. cheap fluro tubes)

I got my very best crop of fluro budz with an even mix, using the cools on the outsides for widest coverage, and some kind of low lumin gro/aquarium bulbs ie:warm (<$6) between, 6 tubes per rack of 3 - $10 shop light fixtures. About $50 per side.

Bought two fixtures, a pair of cool and a pair of warm bulbs, here's a photo of the new set up:


Cool are up top, warm on the sides. They seem to be getting MUCH better light now.. the cool seems to penetrate so much better than the warm.

Everything look okay?

I should have just about 21,000 lumens total now as well.

If you find some Gro Lux bulbs that aren't priced too high go ahead and get some they make a Huge increase in stem thickness during Veg., use them as a mix with cool white or by themselves.

Now here's the trick . . . you need to get your plants as close as possible to the tubes, even touching here and there, as long as veg isn't up against the ends of the tubes, which can get quite warm.
Because the plants aren't all the same size, and the fixture is a 4' plane, keep the fixture at your max height wanted, then move the plants up, using boxes, books, etc. as shims.
Things are looking much better.

Mmm great idea, thanks I'll definitely do it.

Get some jack chain and a pair of hooks, that way when you need to move your fixture you just change links on the chain. Easiest thing to do by far, unless you hook up some electric motors and go with the push button method.

try wide spectrum it is hard to find on package but thay are only 7 dollars and at lowes thay are better than cool or warm thay are the closest to hps spectrum and run alot cooler but a mix of day light spectrum and wide spectrum is best for vegg

floros work great , not as good as mh/hps lights but the heat from floros is much more managable. i use 4ft 28w per from homedepot,lowes. $30 you get a 2 bulb fixster with ballast and 2 bulbs
