Good tips. We have a dehumidifier in the greenhouse to control moisture. Have not had any mold issues, but we did get fungus gnats before the dehumidifier. You might want to try Muncher cucumbers. We are on our second year with these seeds. It's early, self-pollinating and incredibly prolific. Good quality 8" cukes too! We grow this and Orient Express. I'll check out Sweet Success for next year.
