If you go back to the "Starting Daylilies Seeds" Thread, you will see there is a discussion about lighting seedlings. From what I get out of that discussion is T-8 shop lights are the best buck for the money for this type of use. Because I have an unused T-12 shop light, I am currently using that to light my seedlings. I use Becky's suggestion of a warm bulb and a cold bulb for the unit. A cold bulb has a color rating of 4600K or higher. Cold bulb emits blue white light. A warm bulb a color rating of 3000K or less emits yellowish white color. If you are looking to grow seedlings to be transplanted later in the garden when the weather warms up, then cool lights are all you need. I don't think a warm bulb is necessary for growing seedlings. According to a web page I read, warm bulbs are only needed if you want the plants to bloom indoors.
