We did not go out to the greenhouse yesterday, but my wife went in today. She noticed that on about half of the plants - all on one side of the greenhouse - there's a bit of white fuz/mold growing on the soil. She also noticed on the inside roof a good amount of moisture. Seems to make sense - inside the hothouse, watering plants regularly, moisture evaporates and hits ceiling with nowhere to go. The temp gauge has a humidity reading - 48%. Is this high? Too high? Any thoughts on preventing the mold? Continue to water the plants, but go in daily and wipe the ceiling off?
Thoughts? Thanks in advance.
