When used with high intensity grow lights, additional CO2 in the grow room can result in drastically higher yields, and a decreased time to harvest!

What is a CO2 regulator?

The CO2 regulator is responsible for controlling how much CO2 is released from the CO2 tank. This is not to be confused with a CO2 controller, which is also essential for turning on/off CO2 devices, and monitoring the levels present in the atmosphere.

Some of these regulators include a CO2 timer or controller.

For a detailed guide, check out our article on how to use CO2 in the grow room or grow tent. We also have a grow room CO2 calculator to help you determine the flow rate of your CO2 device, to give your plants exactly what they need.
