Fuzzy "cobwebs" growing on soil?

Hello

I'm here today to ask about my sweet peas. I planted them about 4 weeks ago in my heated propagator (to over winter), but moved them into the kitchen windowsill, as eventually they grew to tall for the propogator. I've noticed 2 things since they've been moved:

• the leaves on every plant have wilted and then have gone back to normal after a day
• where the seeds were in the soil there's what looks like cobwebs on the soil.

I am personally more concerned about the "cobwebs" on the soil as I am not sure whether it is mold or mildew, I'm clueless

I'm not sure if the pots are too small, but to give you an idea they have 3-4 pairs of leaves (each plant) and they are in individual cells.

Has the moisture from the propogator caused mold, or what? Help!!

 

Sounds like Damping off fungus. Usually occurs with seedlings indoors in the winter.

You could try a copper based fungicide and you're right about the humidity, has the propogator got a vent?
