apapjim,

Yes they make them. Here are three manufacturers and names of their bulbs. HD or Lowes should carry them, just ask for Fluorescent Plant Grow Lights

AgroSun - Fluorescent Tubes
Sylvania - Gro-Lux Fluorescent Tubes
Verilux - Full Spectrum Fluorescents

They even make multispectrum LED lighting grow panels for indoor growing.

As Lou said they do make the grow bulbs but they are 20 X more expensive than normal fluorescent bulbs and completely unnecessary. I use 4 foot shop lights with one cool white and one warm white normal bulbs and the seedlings do great.

1. Set the light so it is just about touching the seedlings, no higher than 4 inches above the plant.

2. Seedlings hate to dry out and need fed so you have to supplement the potting soil you start them in. IMHO the easiest way to kill two birds with one stone is to go fool proof and simply wick the pots with yarn and let the wick hang down in the weak fertilizer solution. The plants get exactly the water they need and fertilized constantly. The results are large thick stemmed robust seedlings which require very little attention.

Bamboo,

What do you use for the metal rack to set the cups on over the fertilizer solution? Also specify where you found it, I would like to try that for my starters this spring. All I can think of using is an oven metal bake drip pan and rack.

I didn't know the price of the fluorescent grow tubes were expensive because I use the LED lighting grow panels. I like the idea they are cold to the touch when lit and will never burn a leaf and cheap to run.

Lou,

Below is a pic of mine from this winter or last. Note that I did raise the lights all the way up for the picture.
What I use is a couple old sets of closet made storage racks. You can see the white yarn wicks especially on the tomato seedlings in the left front of the picture. A good easy alternative is the egg shell light difuser panels from Lowes or Home Depot (PLASKOLITE 23-3/4" x 47-3/4" Egg-Crate White Polystyrene Light Panel). (see link below) You just set the panels on top of the plant flats that hold the water. You just have to then hang the lights above and use the chains to adjust.
