Docs Supplied By HydroGarden: Digital CO2 Controller

The Compugas is the most innovative and versatile CO2 timer available today. The Compugas will allow precision control over the CO2 environment in the grow room without the necessity of expensive infrared dosing technology. It incorporates powerful and versatile software in conjunction with a "user friendly" plain language display with very wide range settings.

The easy to read, 2 line LCD shows instructions in plain English and walks the user through 5 simple steps to program the unit for CO2 injection and fan operation. In addition, it uses an advanced photocell that cuts off the flow of CO2 during darkness, while still allowing fan operation. Adjustable wall hanger and stand incorporated into the unit. Features AutoCalc which allows for automatic volume computation with measurements in both metric and imperial. Full instructions are provided with the unit.

The Compugas is a separate unit, a CO2 regulator will still be needed. Why not purchase a complete kit and save. Add a Prima Controller for added benefit.

What are the Benefits

The benefits of the Compugas are that the unit will allow the maximum range of settings with the minimum injection time. Allows you to maximise your CO2 by only injecting the CO2 required, thus no wastage. Set the programmes in as required and leave the Compugas to do the rest. The Compugas is relatively maintenance free, the user need only check that adequate CO2 is available. Using the Compugas means that there is no need for expensive infra red units as the chart supplied will demonstrate the injection time, giving an optimum level of CO2 in the growroom. Use in conjunction with CO2 release kit and / or the Prima Controller for extra benefit.


The Compugas is guaranteed against manufacturers defects to withstand normal use for a period of one year. Damage caused by misuse, abuse or failure to follow instructions is not covered. Should you experience any problems please contact the place of purchase for return authorisation and repair or replacement. A receipt must be produced to obtain any warranty repair work or a replacement.
