The fan and filter are both in the tent and it ducts straight through the floor out of reach in my tiny room.
Thankfully I think I figured it out...
The little UIS plug from AC Infinty must've shorted out internally.
I went in blind and could feel the heater working. Checked my controller... that port is "off." I unplugged the control wire from the controller for that port, went back in the tent, still running. I just shut the heater off manually. What the hell? Those things only last through one grow cycle? The one running my humidifier hasn't messed up but apparently the added amperage of the heater was too much for it. Aren't they rated for 15 amps?
Thankfully I have a spare UIS plug but how long til that one shits out? I mean... it does run quite a bit while the lights are off, but damn. It's so easy to just keep the AC in the lung room running low cool all day. It stays in the mid 60's there. I don't wanna rely on the dial on the heater. I'll investigate a little closer when the lights come on in an hour and a half.
So close to finish line too... yeesh.
Thanks for the speedy reply,
