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 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.
