CO2 Controller for Grow Room
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. 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.
