The humidifier is working well. I'm not at 75% and 79f--pretty much perfect. I have it in the center between the four pots. Only possible issue is the fan is in a corner and blow across the top of the humidifier. Much of the fog is blown directly over the pot in the opposite corner. My tent is only 32x32, perfect for 4 5gal pots, but that means I don't have room to put the humidifier in a calm, windless corner. Not sure if the plant, once it's bigger, is going to suffer from being in the line of fire or not... In a few weeks, I hope not to need the humidifier, though.
One option is to get a humidity controller and have the humidifier hooked up to the humidify outlet and the fan hooked up to the dehumidify outlet... That way they're never running together. I don't think it's necessary, though. Really tiny water droplets are almost bouncy--the affected leaves won't become saturated I don't think.
