I run a T6 in my 5tent and another in my 4tent, with the controller attached to the finishing piping fabric (poked small holes with an awl) with two twist ties. They are NOT Bluetooth/wifi. Both are individually ducted to the outside with a louvered & screened cover. The ducting is visible, second tent from right (first tent obscures ducting)
Today, a T4 was installed into the 3tent
As soon as I have the dollars (and before summer heat) the last tent will also get a T4. The vent and ducting for it is already installed.
The AC Infinity fans are used for exhaust/humidity control. I have additional fans in each tent, some oscillating, some not. They, like others have said, run 24/7, creating nice vortices and preventing stagnation.
