Check the variety before you plant. 24 hours of artificial light will help speed the germination process. This is when the clear plastic covers are great because they keep the soil surface moist while the seeds get going. Just remember to keep them out of the sun. The distance the lights are kept from the plants is critical.
Florescent lights are only effective when they are within a couple inches of the tops of the plants.
I let mine go till the tallest plants in the flats are actually touching the lights. Then I move them up but only an inch or two. I have my lights hung on chains to allow me to easily raise or lower them. They will work great and you will be happy with the progress your seedlings are making at least until you get the power bill. They have developed a new plant light that promises to cut costs and provide more light.
