If you only found 1, then it likely didn't come from your collection. The gnats themselves don't do much damage, but the larvae will. Look at the surface of your media and check to see if there are any tiny transparent worms on the surface with black heads. If not, you'll be fine. If you do, you can just put small portions of mosquito dunks/chips into your seedling watering tray. But as I said before, it may not have come from your collection. If you do end up seeing more over the course of a few days, then you'll need to use the method I described above.
