You want a cool white (around 6500k) for vegging and a warm white (2600k) for flowering.

If you are using tube type fluros, GE Kitchen and Bath 40s work well for flowering. For vegging, the "el cheapo" shop light tubes work just fine!

For CFLs, you just have to read the package and hope they have it listed somewhere. I found some small straight tube CFLs at the Dollar Store that are bluish and nice for veg- if you get a mess of them. Walmart had some big, cool white, "curly" bulbs that were more cone-shaped than most.

The usual "curly" bulbs are usually "warmer" and will work for flowering.

Now get reading! Start with the stickies in the grow section! :thumbsup:

SO if I can get any advice, I also Rating: 5
