As JT says, one warm white paired with once cool white is an inexpensive alternative to 'grow' lights and works quite well. That's the combination I have always used in the past. This year, as an experiment, I decided to try the Philip's 'Daylight' bulbs. They are working really well. Both my African Violets and my seedlings have done really well under them and they're less expensive than 'grow' lights. Also, my light fixtures are 3' instead of the more common 4' and I can't find 3' 'grow' lights anyway... Whatever light you use, it is important to remember that fluorscent bulbs lose their strength as they age so, each year for your seedlings, it's a good idea to get new bulbs even if the old ones haven't actually burned out.
