Description
Brew your own CO2, on tap, with automatic solenoid control
The CO2Gro Home Brewed CO2 Generator produces carbon dioxide from a simple sugar-and-yeast reaction inside its 12 litre stainless steel cylinder, then delivers it through a built-in solenoid valve and regulator so gas only flows when your controller calls for it. It gives a grow room the steady CO2 enrichment of a bottled gas system without the cost or hassle of gas refills or delivery.
What's Included
- CO2 Generator Cylinder – 12L stainless steel reaction chamber
- Solenoid Valve and Controller – switches gas flow on and off automatically
- Regulator with Pressure Gauge and bubble counter for flow visibility
- Filter with Dry Filter Media
- CO2 Tubing and Funnel
- Power Adaptor and instruction manual
Key Benefits
- No gas bottle refills or exchanges – CO2 is brewed on site from generator material (sold separately)
- Automatic solenoid control – pairs with a CO2 controller so gas is only released when levels drop
- 12L capacity – sized for a serious tent or small room
- Stainless steel construction for a reaction chamber that holds up to repeated charges
- Simple to recharge – refill material available separately when the charge is spent
Sealed grow rooms strip CO2 out of the air within the first hour or two of lights-on, and once ambient CO2 drops below outdoor levels, photosynthesis and growth rate slow down even with everything else dialled in. A home-brewed generator keeps a steady supply of gas on hand without the recurring cost of bottled CO2 refills, and the solenoid means it only releases gas when your controller says the room actually needs it.
How to Use
- Charge the cylinder with CO2 generator material (Material A and Material B, sold separately) following the included instructions
- Connect the regulator and solenoid to the cylinder outlet
- Wire the solenoid to a CO2 controller so it opens only when your target PPM is not met
- Run the supplied tubing into the grow space and route the gas away from direct airflow onto plants
- Monitor pressure on the gauge and recharge the reaction chamber once output drops off
