Controllers, PPM Monitors

Use CO2 in your garden to increase plant yield by up to 20%. Plants benefit most from CO2 when the PPM (parts per million) of CO2 in the air is between 1000 and 1500. Ambient is usually about 300 PPM. Use our CO2 Calculator for Grow Rooms to find out where to set the flow gauge on your regulator, and how often to turn your regulator on. New to CO2 enrichment? Read our CO2 Buyers Guide and 'How To.' CO2 Controllers help the dosage of CO2 into your grow room. They often have PPM Monitors built in to help the controller keep the PPM of CO2 in your grow room within a beneficial range.

CO2 levels in the air are measured in PPM (parts per million) and ambient is usually about 300 PPM while plants benefit the most when the CO2 in the air is between 1000 and 1500.

CO2 monitors help to diagnose the PPM of CO2 in the air and CO2 controllers are capable of maintaining the optimal level of CO2 in your grow area by sensing the PPM of the ambient air then turning your CO2 generator/regulator on and off as needed. Many monitors come with some form of logging and can even monitor relative humidity and temperature along with CO2.
