THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are scaling up your CO2 injection because your current setup cannot maintain high concentration levels during peak growth
  • You are optimizing for a smaller space because you need to restrict gas output without buying an entirely new generator

  • Plugging individual burners is a smart way to throttle heat if your room gets too warm in the summer
  • We prefer these electronic ignitions over pilot lights because they stay lit even if your ventilation is powerful

  • Users report that the tip-over switch gives them confidence when they have to move the unit for routine maintenance
  • Growers who swapped to this model say they stopped chasing inconsistent gas levels after installing the 12-foot hose

BluePrint CO2 Generator 4-Burner Liquid Propane

Keeping CO2 levels consistent in a standard-elevation grow room shouldn't require complicated equipment. The BluePrint CO2 Generator 4-Burner Liquid Propane uses four preinstalled brass burners to generate a steady 10.6 cubic feet per hour of CO2 from liquid propane, specifically engineered for growing spaces at or below 4,500 feet elevation.

Removable plugs let you deactivate individual burners, so you can scale CO2 and heat output down to match a smaller growing space without needing a different unit. To maintain ideal PPM levels automatically, pair this unit with a BluePrint BCC-1 Digital CO2 Controller or the more advanced BluePrint BCC-2 Digital CO2 Controller w/Fuzzy Logic. Electronic ignition and dual solenoid valves eliminate the open pilot flame for safer, more reliable starts every time.

A safety tip-over switch automatically shuts off the gas supply if the unit isn't upright, giving you extra peace of mind. For constant atmospheric tracking, you can add a BluePrint BP CO2 Monitor w/ 15' Sensor Cable to your setup. The generator ships with a gas regulator, 12-foot hose, and hanging hardware, backed by a 3-year warranty.
