Seedlings with white fungus

I have a few week old seedlings that contacted this white fungus on them. Why did this happen and what should I do with them. I currently washed the fungus off but I'm nervous it will spread to the other seedlings.

Thanks for your help

Toss bad ones in trash right next to the dome. Domes are for cuttings and not necessary for seedlings. If you feel it’s easier to keep soil moist until they pop, fine but take it off when they do

Idk what kind of fungus/ mold that is but might not be a bad idea to clean up . They want more light also

Thank You. I just dropped my light, so hopefully that helps. Im a bit nervous to drop my dome because these seedlings are in my basement and its a little chilly down there. They are under a heated so that should help.

ditch the dome high humidity is causing that mold it can also rot the stems of seedlings. dont use a dome find another way to heat the area. also think about spraying with 1-2% h2o2 solution to disinfect. but no dome.

You don't need a dome, use a heat mat if you are concerned about temps.

I too use a dome, because I germinate in rockwool and it retains moisture a little better with high humidity, but that is exactly the reason yours are getting mold.

Ditch the dome. Its only useful with germinating in rockwool, and thats only because Im busy and lazy. When you get to cloning, thats when the dome becomes your best friend.

Ok.. ill lose the dome
