Sigrow builds AI-powered sensors and cameras for greenhouse growers, measuring leaf temperature, VPD, root-zone moisture and drain so they can steer on what the crop actually experiences

Sigrow is a Dutch AgTech company, founded in 2014 at Wageningen University and headquartered in Ede. It builds AI-powered sensors and computer-vision systems that show greenhouse growers what the crop is actually doing, not just what the climate box in the aisle reports.

The Stomata Camera fuses thermal and RGB imaging to read leaf and fruit temperature, stomatal behavior, leaf-level VPD, and Real Transpiration Rate. The Pixel measures microclimate at the crop canopy. Soil Pro+ and Soil Mini track water content, EC and temperature in the root zone, whether that is rockwool, coco, perlite or soil. DrainSense reads the water leaving the root zone, drain EC, pH, volume and gutter weight, so growers steer irrigation with the drain, not against it.

Everything connects to Priva, Hoogendoorn, Ridder and other climate computers over API, so growers add Sigrow to the system they already run instead of replacing it. Sensor data lands in one free app the whole team can read and act on, with alerts before a problem becomes a loss.

The systems are built by growers, for growers: quick to install and grounded in the Plant Empowerment approach to climate, radiation, moisture, transpiration and water balance. More than 1,000 growers across 50+ countries use Sigrow to raise quality and cut water and energy use, and to understand their crop better.
