The T-1 Pro is ideally suited for both beginners looking to put together their first grow kit, and 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 micro-environment. 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 and 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 acts as CO2 monitors, and are designed specifically for our CO2 regulators.
