Intro: Tall, thin seedlings are common — and easy to fix.
1. Increase light
Legginess means they’re stretching for light.
2. Move them closer to a window
Or use a grow light if needed.
3. Reduce heat
Warm rooms make seedlings shoot up too fast.
4. Turn the tray daily
Stops them leaning one way.
5. When to repot
Plant them deeper to support weak stems.
Summary: Leggy seedlings need more light and less heat.
