Unless you have all AC infinity devices to control the environment in your grow room, I wouldn't even consider it. And if you had more than one tent to control, it won't do that. It has a dual zone VPD setup, but that's really for controlling a lung room and the other controlling the tent VPD.

CONTROLLER 69™ PRO+ is a bit of an overkill in my opinion. Yeah you can control twice devices as many as the CONTROLLER 69™ PRO, but how many devices do you need for one tent, because it will only control the environment of one tent. It only has one VPD sensor so it can only control one tent.
Now if you had a big tent, 8x8 or bigger, then I can see it as being a viable option. You could utilize the extra outlets for the more lights and maybe a second exhaust fan or even an inlet fan.
I have three tents so I have three Pros, until the next grow. I have another so that I can control my AC Infinity humidifier by my phone and to run the under canopy lighting on the 4x4 tent.
My 3x3 tent uses all four controls. Two Smart plugs for the supplemental lighting, One to control the main light and one to control the fan.
Just my two cents.
I like my current setup. With the additional controller, the only thing I can't control by my phone
anywhere I'm located, is the heat.
