I love this thing. Measures CO2, and releases it at what you set it at. Controls humidity in either direction, if you have both a humidifier and dehumidifier. Air conditioner (provided you have auto-restart on the AC) keeps temps stable. Can also plug in exhaust fan instead of AC. Waiting for late Fall/Winter to plug in a heater. Also has option for datalogging through your PC. I actually run a second controller to kick on a second humidifier for night, along with exhaust and intake fans at night because there is only one outlet per device, and I use AC with a humidifier with the first controller. I am adhering to the Vapor Pressure Deficit chart, and this setup is allowing me to keep fairly close to the parameters. I have a humidity/temp logger that reports back to my smartphone, so I can keep up to the minute results. It is nearly impossible to adhere to the VPD chart inside a grow tent, but I'm sure getting close!Read full review

I like the unit. works great. does everything. day time/night time Humidity/Temp/co2/ ventilation. how ever all 4 separate units. -humidifier -portable air conditioner -co2 seloniod& tank -ventilation. all have there own program able settings. and can be pluged in to cheep timers. In realty, the only added bonus that this unit has is the "FUZZY LOGIC" feater that monitors and adjusts Co2 levels as needed lowering the coast of co2 refills. and even then. you can do the math in size of room and adjust the regulator on the tank and set to a timer. so if your on a budget, for the over priced 700$ in canadian founds. a parson con totally control the room atmosphere with out this thing. but don't get me wrong. it's a cool little unit. just don't think it's wOrth what they charge for it
