Can a plant recover from temperature shock?
Some will start dying the second the temps dip, but others can regenerate from healthy roots below the soil even if the top part of the plant is completely frozen.

However, if one of your seedlings has died from damping off, it’s very likely the same fungi or bacteria that killed it is also present around neighboring seedlings. In addition, some types of fungi, like Pythium, have motile spores that can actually move in wet soil, spreading across entire seed trays.
