The CO2 Monitor & Controller for Mushroom Farms automatically exhausts grow room air when carbon dioxide (CO2) levels get too high.

  • Accurate CO2 Control
  • Simple to Install and Use
  • Easy Fresh-Air Calibration

The CO2 Monitor & Controller for Mushroom Farms lets you set a target CO2 level. Using advanced hysteresis logic, when the CO2 level in the room goes above the target, power is supplied to an exhaust fan via the built-in 100-240 VAC 5A piggyback power cord. When the CO2 level drops below the target, the power is turned off.

Need to monitor CO2 levels remotely? An industry-standard 4-20mA analog output lets you monitor CO2 levels from most environmental control panels.

Best of all, the CO2 Monitor & Controller is easy to install and use. Simply mount the unit inside your grow room, (all cables and hardware included), plug it into a standard wall jack, plug in your exhaust fan, and it is ready to protect your crop from high levels of CO2

So far so good

The co2 meter seems to be accurate. It always goes back to 420 ppm when I'm away from the house. It'll be about 2 to 4 weeks before its really put to the test.

What a difference it makes to control the CO2 in a mushroom grow!
