Variac thermostat setup

Thats very surprising. The main reason people use variacs and auto-transformers is to have no hum. Are you sure you were sold one? Do you still have it?

Are you running HPS or led ? Sometimes think with smaller led/tent, a non-venting scrubber setup can be attractive. Especially so, in cooler months.

Hps never tried a led light before

Is it an SMS fan controller?

As they’re not variac controllers. So you’ll still get a certain amount of hum.

I use the single fan speed controller from sms. When you set the idle speed to the lowest you get hum but at 1/4 of the idle selector there’s not much Hum at all with my system air RVK150A1.

I have found this on the picture but from this thread below

seem interesting tho I don't understand what means at the very end swap to the orange does understand?
