The T-1 Pro CO² Controller is the most advanced carbon dioxide regulator on the market. It accurately creates the desired CO² levels in your grow room, making it one of the most effective CO² regulators. Easy to configure, yet packed with professional features it is ideally suited for both beginners looking to put together their first grow kit, as well as the more seasoned urban gardener vying for the biggest buds.

Provide your crops the consistency they need to gain the highest possible yields with its automatic CO² dosing counter. It’s adjustable pulse dosing allows you to maintain a stable CO² level in your microenvironment. It also has a dosing delay function, which enables delayed activation of CO² enrichment in your room, making it the smart sensor that can ensure your grow stays in an optimal condition even in your absence. Keep track of your progress with its automatic logging function, which has a storage capacity of a full 7 days.

With its highly sensitive ppm sensor, the T-1 Pro is adjustable from 300ppm to 2000 ppm or from 300ppm to 10000 ppm. From the clear display, you can read the actual values of the connected sensors as well as the minimum/maximum values. The T-1 Pro Controller automatically switches between day and night settings by means of light detection and thanks to the built-in calibration function, you can calibrate your CO² sensor in fresh air.

The T-1 Pro comes without a sensor. It is compatible with our range of Techgrow carbon dioxide sensors, which act as CO² monitors and are designed specifically for our CO² regulators.
