The Digital CO2 Controller is an essential device for maintaining adequate carbon dioxide levels in indoor cultivation. It allows you to manage CO2 generators safely and accurately, ensuring a controlled environment for better harvests.

The Digital CO2 Controller from VDL has been designed to regulate the switching on and off of propane gas CO2 generators in indoor crops. It has an external sensor that measures in real time the concentration of parts per million of CO2 present in the environment, displaying the information on a digital LCD screen.
Among its most outstanding features are configurable audible alarm, automatic day and night detection, and screen backlighting to facilitate reading in dark rooms. Its measurement range covers from 0 to 5000 ppm, with a margin of error of only 5% for values below 3000 ppm.
The controller has two connection sockets: one for power supply and another for extractor or fan. This allows excess CO2 to be expelled or, failing that, dispersed evenly in the growing area.
The built-in 4.5-meter probe allows measurement from the center of the tent or room, ensuring more accurate and reliable data. Thanks to its compact design (158 x 106 x 50 mm, weighing 700 g), it can be easily installed in any indoor space.
The Digital CO2 Controller is designed to offer complete control in indoor growing environments. It is an essential tool in cheap indoor grow tents and in professional installations where the aim is to increase cannabis yield through enrichment with carbon dioxide.
Its precision and ease of use make it a key element among the cannabis growing accessories available at Hydroponics Blanes, a Grow Shop in Spain recognized as a trusted Grow Shop.
