The 3 options I've found in reference to seed starting with fluorescents:1 grow bulb and 1 standard bulb1 warm white and 1 cool white bulb2 bulbs of any type All these bulbs I've found at the local big box hardware store. some of it depends on how long your keeping your seeds under lights. If your just starting them and letting them get a few inches tall, most likely any combination from above will do. If your keeping them under lights for longer, you want something more full spectrum and probably more total light per plant.
