Cold CO2

Compressed, bottled CO2! Safer option for plant enrichment in that no toxic by-products or additional heat can be produced. Compressed CO2 comes in cylinders stored under high pressure (1600-2200 psi). Equipment such as a pressure regulator, flow meter and solenoid valve and timer are required to set up this type of enrichment system. CO2 is injected into the growing area via the pressure regulator and flow meter which is controlled via a solenoid and timer. One pound of compressed CO2 gas contains about 8.5 cubic feet of CO2 gas at normal atmosphere pressure.
