Hot CO2

 You can vent the top of the FHD CO2 Generator to remove a good portion of the heat the generator creates. The custom-built, solid brass impinged burners ensure a clean-burning and constant blue flame.
The gas valves incorporate the latest technology available by utilizing a glow-plug igniter; no flame, NO HEAT, no gas wasted and no pilot to re-light. When one CO2 burner lights, it lights the next, then the next, and so on.
FHD Co2 Generators are available in 4, 6, 8, and 18 burner systems. Propane generators require a propane tank of any size (the ones used for barbeques will work just fine) and all fittings and tubing are included. The Natural Gas models are designed to be hooked up to a natural gas line (existing gas lines for clothes dryers are perfect) and they already include the necessary regulator and tubing.

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.
