These CO2 Enrichment Systems are heavy-duty and built to last - they are not the cheap models that many other stores sell. They feature an accurate, easy to adjust CO2 flow meter, a preset adjustable regulator, a pressure gauge, a solenoid valve and complete instructions. Each unit also comes with the tubing needed to disperse the CO2 evenly throughout your room in one of two ways. The Drip Ring Method utilizes a nylon "T" that allows growers to mount a ring to the ceiling of a growing environment with 15' of tubing that disperses CO2 evenly as it drops evenly down over the garden. The Fan Method is used simply by attaching the tubing to the back of an oscillating fan, slightly tilted upward, for even dispersion.

For those who wish to time their bottled CO2, the IGS-11 offers metering as low as 30 sec of ''ON'' time and 1 minute of ''OFF'' time with the ability to reset itself to the beginning of its cycle after the area was vented by a thermostat, humidity or timer. The IGS-11 also has the ability to defeat CO2 production during the dark cycle. For those who wish to be very exacting with their atmospheric concentrations of CO2 we offer an infrared CO2 monitor controller (IGS-61). This device will add CO2 only when required and keep the level at your predetermined enrichment value throughout the daylight period.
