How do I get rid of mold in my soil

I planted new cherry grafts in my greenhouse with temps going from 45 in the night to around 70 in the day. I opened my greenhouse to look at how the grafts are doing and noticed mold forming in the soil, is this mold harmful for the newly planted rootstocks, and is there a way to get rid of it?
Here are a few pics


You can mix baking soda with warm water and use a mister bottle to spray the surface, takes a day to kill,may take several applications depending on depth of mold.

Increase airflow, water less, cinnamon… see link above.

That’s not needed and is counter productive. The soil is supposed to be full of mold, it is part of the normal biota and nuking it would nuke the beneficial ones that work alongside with your plants.

It is like the normal biota in your body, where there are as many microbes as there are human cells. You should not nuke those either.

For that particular mold, sunlight.

You can’t.

If you think that looks bad this goey mess was growing on a purple sand cherry:

Harmless.
