Had to pick up a humidifier for the greenhouse, I'm still tweaking the heat and humidity to try to get the right balance on both for the citrus trees, When temps are down in the 50-60 range, I'm getting 55-80% RH in there, But when the sun starts heating it up to 80°F, My RH% is dropping into the 20-30% range, So im getting an imbalance, Optimum range for temps is mainating 65-75°F during the day, And 55-65°F at night, With the RH% between 60-80%, I'm going to program the humidifier to a constant 70% RH to prevent unwanted guest and mold.
