Variable CO2 Generator (VCG-6)

The Sentinel VCG-6 CO2 Generator has two models, the LP (propane) and an NG (Natural Gas) model. Both come complete with (2) clean burning brass burners pre-installed and the appropriate regulator & hose. For the smallest set-ups, the user can replace 1 of the 2 burners with the plug provided with the unit. That allows the unit to produce 3 cubic feet per hour instead of 6 cu. ft. / hr.

Carbon Dioxide (CO2) is critical for all plants. Normal atmospheric air around the world averages about 380 Parts-Per-Million (PPM.) When plants are provided higher levels of carbon dioxide, they can grow faster and larger.

Note: The burners on the VGC-6 have been selected to operate correctly from sea-level up to 4500 feet elevation. If you are at high altitude (4500+) and notice yellow flames, please let us know. Special high-altitude burners are available.
