I painted it black as there's a little green led in there. There's no power button, so it works fine with any controller or timer.
At times I used it for the cooling effect with an inkbird humidity controller running the exhaust fan.
Update: I’ve ordered an Inkbird and an evaporative humidifier, Honeywell to go inside tent. I’ll pay attention to the VPD chart and adjust humidity to temperature. Just a little more control than outside! Thanks everyone for your help.
