Merdle,

Whether you are using humidity domes or placing plastic wrap right over the flats or pots, you need to air out the containers for half an hour to an hour once or twice a day. I've had seeds germinating under humidity domes for weeks and this airing-out procedure, especially if you use a small fan or open window (not on a freezing day!) for air circulation, keeps the mold from forming.

Planting your seeds into seed-starting mix, not potting soil (although things often turn out OK with potting soil too). Keep it moist but not too wet. If the surface starts to dry off during airing-out, moisten it with a plant mister before putting the cover back on.
If you follow these steps, you should not have any problems with mold or fungus.

I have used the hydrogen peroxide mix 10 parts water to 1 part peroxide to spray / water my seedlings many times and do not get mold issues. I would not start over at all , I hope this bit of information helps .

Best Regards & Happy Planting
