I have lost several begonias (especially rex types)to last year's scorching Tx heat and I plan to prevent the catastrope this year! I was wondering if anyone has ideas for retaining humidity and cooling down the sunroom a bit. My plants are housed in a screened porch/sunroom, with windows all around and a roof (non glass)on top. I keep the windows open in summer and plant to use a misting coil on a timer. That usually leaves a lot of water on the ground (carpeted with outdoor carpet). Is this humidity ok for the plants..what about mold issues?
Suggestions please, thanks.
