My light fixtures had a mixture of warm and cool fluorescent bulbs in them. I kept the plants close, like others here are suggesting. You move the fixtures up as the plants grow taller. Mine were on chain link with s hooks. I could raise or lower the light fixture as needed. One thing I had to remember was not to torque the fixture, but to keep it even on the diagonal. Not necessarily level, sometimes I had one end higher than the other, but still even. Am I describing this adequately? This extended the life of the fixture and perhaps even the bulbs.
One other thing not yet discussed is simulated wind. I had an oscillating fan downstairs near the plant shelves, of which there were six, two sets of three. Wind stresses the stems, in a positive way unless you're talking about a serious weather event, making them stronger. The fan did this in the house. That meant when things went outside, they'd already been stressed in that manner, which made them less vulnerable to snapping in half. It also helped prevent any diseases caused by wet, like damping off. Yes, that meant watering more often, but I just kept a spray bottle for that, as often all I needed was to dampen the soil surface, not the entire flat, when things were just in the germination stages.
You also need to feed your seedlings some dilute form of fertilizer unless the soil you've chosen contains something.
Faith, are there any seed starting articles in that mess of stuff I mailed you?
