Day 4 seedling in rooter - overwatered, but root shooting out bottom? What to do? Dry? Transplant?

Hey mate! First of all chill out mate. Doesn’t seem wrong, at least in that photo. You can move to a bigger pot, and in this stage you can only spray the medium gently, because she is very young and don’t need much water, you can put a bottle in the top of her and spray the interior of the bottle to increase the relative humidity, make a little hole in the bottle! On thing that can help you is check the medium with a little stick or Half of you finger, if is moist the medium don’t need more water. Relax mate ! Wish it helps 🤙🏻

If you sure you overwatered pot her, that might soak up the extra Water. I mean since the Roots already showing there is little reason not to unless you had her in a cup to transplant her a bit later.

If roots are coming out of the bottom, transplanting is your best course of action. Cheers,.... Organoman.
