A combination of high leaf area in a tiny space, and the drop in temps at lights off. Lights on I'm between 35 and 45%, but lights off I'm getting over 70%. That kind of swing, especially with the high swing in temps, really promotes PM and mould.Why are you getting such high humidity when I'm barely getting up to 40% rH?
The fabric pots also let moisture evaporate from the sides and bottom.
