Hello all, I have some double Shirley seeds planted in three medium containers facing southwest on a window sill inside.
The area I live gets hot on a sunny day, easily 80 F, the soil sometimes 100. Shade and water with a spray bottle help some, but the water quickly dries. I placed a plastic bowl cover and the moisture from evaporating, but the temperature stays in the high 90s, so , does anyone have any suggestions on how to keep the plants cool? A preferred temperature is room temperature , or mid 60s.
