Here's my usual setup to compare, showing the aforementioned condensation in action, and a bit of recycling too.
These containers are in bright shade (where I like to start my seeds, until they have germinated).
After I water to saturation and let all the water exit the container from below, I put an old plastic lid underneath it (pretty tight fit down there) and plastic wrap on top of it. Evaporation both ways is mostly blocked this way, but the soil is never ever supersaturated. Second picture shows baby aloe trees sprouting underneath. I will leave them under there until they are growing true leaves, then take off the top, then later take off the bottom and begin the stepwise process of gradually moving the seedlings into the sun.
