I have no idea but fungus does not need to be a problem. It is definitely not inevitable. There are fungal spores around us all the time but they need warmth and moisture to grow. If you water your seeds carefully and don't over wet them then you will not get fungus.

you can avoid fungal growth by having air circulation and sprinkling powdery sphagnum moss on top of seeded soil.

Ha ha. Might be worth it in a pinch. I doubt it would hurt but I use Fung Onil. Its not expensive at Walmart. Good stuff whenever you are concerned about dampening off.

Can also spray a mixture of baking soda and water on seeds/seedlings. Keeps fungus at bay. I use this mixture on my outdoor garden plants like phlox that are prone to fungus.

I'm glad to see someone mentioning this. In the university laboratory I found sprinkling powdery sphagnum to be quite helpful.
