FAQ
Question: 

Will a fluorescent light fixture provide sufficient light for seedlings?

Answer: 

A standard fluorescent shop fixture containing two 40-watt tubes provides sufficient light to grow seedlings indoors.  For best results, place one cool white and one warm white tube in each fixture.  Place the fluorescent lights no more than 4 to 6 inches above the seedlings.  The lights should be on for 12 to 14 hours each day.
