I am currently working on my next grow. Going indoors for the winter. It will be a cfl project. I'm going to get at least 10 of 42w for flowering, and was just wondering what are the best cfl's to use for vegging? Any and all comments and opinions welcome.

CFL blue for vegging and CFL reds for flowering.

Which ones are which though, is what I don't fully understand

How do I tell the diff?

Check the color temp...

"Warm white" or "Soft white" (2700 K - 3000 K)
"White", "Bright White", or "Medium White" (3500 K)
"Cool white" (4100 K)
"Daylight" (5000 K - 6500 K)

"Daylight" for vegging and "Warm White"/"Soft White" for flowering.

Wow at least 10 42 watters. I'm sure you know a small hid would be more powerful for the same watts. Anyways you may want to mix the color spectrum up. Something like 4 blues for veg then add 6 reds as the plants get larger.

you can get 105watt, 5000k pretty cheap and would work better, a lot better, same for 2700k or 85watt and down, check out "buylighting.com" kick ass site for cfl's

Why not just spend the $150 and get the 400watt mh/hps combo on ebay?

You're going to spend way more than that doing a 10 bulb CFL setup.

$150/10 = $15

CFLs are not $15 a piece.

I've found CFLs are more like $2.50 a piece.

As for mounting, you can get a bathroom vanity lighting strip setup for < $10

You can also place CFLs around the sides of the plant, instead of just the one light hanging above.

That's why I went with CFLs anyways. I'm having trouble finding cool whites myself though. I got some GE 3packs at walmart, but I guess they are warm white, according to a PDF I found on GE's website. 1750 lumens for ~$2.50 is fine by me though. I need to find their cool white version, my walmart was out of stock of the 26watters. (The cool white versions are in a blue packaging and say Cool White on the front. Green packing = warm white)..

Here is the PDF from GE's website that shows color temperature and lumens. genet.gelighting.com/LightProducts/images/t04/0000000/r00016v-1.pdf
(match up the product number on the packaging with the grid in the pdf)

Remember, lower color temperature = more red.


edit: This lighting chart makes me see why people suggest HPS for flowering
