I was worried about that too, so I put flaps in the covers, since then though I have found out that a very experienced grower on this forum (Weezard)covers his soil to prevent fungus gnats and he has never had an issue and my plants suffered no ill effects at all.

here`s the post with a pic of Weezards pot covers, his are on the soil, I put mine at pot height.
