New TGA Seedling Questions?????

I started some TGA seeds and they really look too tall (about 4" ).Started in seedling tray on a heat mat. They mostly only have 1 small set of leaves.Will their stretch catch up with them, and how long should I keep the dome over them?

u should have removed the dome right when they sprouted, OUCH!

Add more soil to the cup/container. That's if you have room to add more, what I like to do is start my cups at 1/2 or so full of soil, and when the seedling grows I can add a bit more... roots will grow from the stem there after.

And yes, dome comes off right when they sprout. You could over-water them if they stay in there for too long because the media stays wet for too long.
