Damn, what to do about this seedling?

Good news, my LSD came up! So my barney farm germ rate is 1/1. Problem was when I went out of town for a few days my light never came on. So I found it with a 3.5-4 inch stem, the top was starting to open. I really don't want to lose this one, what do you suggest? I don't think I can add more soil to support the stem wouldn't that kill it. Like if I added another 3 inches of dirt seems like that buried stem would die. So basically I got about 3 inches of streching on a few day old baby.

3 inches is not that bad. Just take care of her, try to hold her to keep her strait if she can't hold herself and she will be fine. You can bury her deeper when you transplant her

Cool beans. She's holding herself so far. When lights are back on ill transplant
