Gas is extremely cold when it escapes from the tank. A quick blast can do damage to skin tissue or eyes. CO2 can also freeze and ruin a regulator. In haste to supply CO2 to the waiting plants, many growers crank the regulator up to a flow-rate that can cause cause regulator freeze-up. This can occur at anything above 20 CFH (cubic feet per hour). Special heated regulators are available for those with a large area, or a shortage of patience. Determining CO2 Release Time At 20 CFH, each minute of CO2 release yields one-third of a cubic foot of CO2 released very good for the big bud. A 10 X 10 X 8 foot room would require a little over 3 minutes of CO2 release.{ add comment }
