ive had it in a dark/warm spot for a few days its about 2 inches now, when i go to put it into my grow box the top drys out the whole plant trys to fall down, any advice?
Add more soil. Cover up that stretch and get the lights closer. She is stretching for the light and she will die without it. I've never heard of not putting light on a seedling as soon as it breaks the surface. It doesn't get 48 hours of darkness when grown outside. She needs light.
Put a cup of water or a wet towel in somewhere. It'll keep moisture up. Maybe laying in front of the intake
Run exhaust and passive intakes. It pulls the hot air out and pulls cool air in automatically by creating a vacuum effect. Intake fans can get in the way. Having exhaust only and passive intakes seems to work better. My experience at least
