CO2 Generator 11 kW

The HotBox CO2 Generator is designed for serious growers running large-scale grow rooms or greenhouse setups that need consistent and controlled CO2 enrichment for their space. Powered by propane or natural gas, this high-output unit delivers up to 11kW of clean-burning CO2, helping accelerate plant growth and boost yields in high-light environments. It comes with an electronic ignition system for easy, reliable startup, and is equipped with a flame-failure safety device for added protection. The fully automatic design allows for integration with environmental controllers, giving you precise control over CO2 levels. Constructed from stainless steel for durability and corrosion resistance, it’s engineered to handle long-term use in high-humidity, high-heat grow spaces. If you're growing on a smaller scale, check out the CO₂ Generator 2.5kW. For mid-sized grows, the CO₂ Generator 4kW is where it’s at.
