13Turtles,
Your seedlings are growing spindley due to lack of or not enough light. They are reaching for light. Plants grown under light need 16 hours of light to grow healthy. The light needs to be 2" above the seedlings to do any good.

I use a timer so I don't have to worry about forgetting turning the light on.
Below is my set up for daylily seedlings. Aluminum foil on the wall helps increase light and bounce it back to the seedlings.
