Everything is looking good. I've consistently noticed the the humidiy reading have been much higher on the weather gauge suspended above the plants than on the humidifier, there has been a pretty wild swing of the humidity between 46% to 80% beween cycles of exhaust fan on an off... I have the exhaust fan set to run for 30min every 2 hours. but the average is about 50 to 55% so I think it's ok.
