Here's how some of our customers use this product...

Monitoring CO2 in Indoor Grow Rooms

The Background: Our customer is commercial indoor grower that utilizes hydroponics and other advanced techniques to optimize the growing environment. They seek a means of monitoring the CO2 level to provide the best conditions for growth.

The Problem: Plant health is tied closely to CO2 levels. Generally speaking, higher CO2 levels increases photosynthesis spurring plant growth. CO2, however, is also a greenhouse gas and can affect human respiratory function and depress the central nervous system in high concentrations. Maintaining a safe level of CO2 while optimizing plant growth requires constant monitoring.

The Solution: We recommended the Telaire T8000 series CO2 monitor which features a reliable low cost sensor with a long life span. With the addition of temperature outputs, the T8000 can give both accurate CO2 and temperature measurement. The outputs from this monitor can be used with a controller to control gas and ventilation, providing optimum CO2 and temperature levels for the growing zone.
