CO2 Controllers

To make sure your indoor plants have enough CO2 to maximize photosynthesis for growth and development, control CO2 levels in all plant stages. CO2 controllers and sensors help you monitor proper levels of the essential gas day and night. Learn More

For your indoor crop to thrive, CO2 should be maintained at 1,500 parts per million in your grown room or grow tent. Any more is toxic to plants; any less limits growth. CO2 is nontoxic to humans at these levels.

A monitor lets you know what the level is in your grow space. A CO2 controller attached to the proper equipment—either tanks with regulators for grow tents or electronic CO2 generators or burners for commercial operations—allows you to set the level and have it automatically maintained. Regulators release the gas from CO2 tanks; you’ll have to refill the tanks as needed. CO2 generators will produce and distribute CO2 on command of the controller.

GrowersHouse offers regulators and controllers for tents and other small spaces, and controllers for a larger grow room or for two grow rooms. Some controllers attach to multiple devices, also controlling humidity and temperature. One iPonic controller, through an iPhone, can control up to four devices in each of two rooms.
