Indoor CO2 Grow Controller and Sensors

When using the proper amount of CO2 each time, the CO2 Controller for Grow Rooms is made to optimize plant yields and assist growers in saving money. This gadget works perfectly in hydroponic farms, grow rooms, indoor greenhouses, mushroom farms, and other settings where higher CO2 levels optimize plant growth.


  • Automatic shut-off during dark times reduces CO2 emissions.
  • Built-in temperature, humidity, and light sensors
  • Dual mode for greenhouse or mushroom applications
  • Controls up to two zones (suitable for small or big facilities)
  • Configurable user interface for controlling CO2 tank and regulator
  • Adjust CO2 setpoints for high and low levels
