Ridder Links Quantified Sensors to Hortimax Greenhouse Controls

Root-zone data is moving onto the same screen as climate setpoints. Greenhouse Product News reported on September 14, 2026 that Ridder and Dutch sensor maker Quantified are integrating Quantified’s wireless greenhouse sensors into Hortimax Plus and Hortimax Pro climate computers—so growers can watch crop and substrate signals next to the automation they already trust.

What growers can see

The wireless sensors cover substrate moisture, drain, weight, and plant temperature. Once integrated, that crop and root-zone telemetry sits alongside the climate automation growers already run in Hortimax—ventilation, heating, humidity, screens, and related loops—instead of living in a separate phone app that nobody opens during a busy harvest week.

• Substrate moisture monitoring
• Drain tracking
• Weight / load sensing
• Plant temperature

Moisture and drain together help flag overwatering or clogged drippers before canopy symptoms scream. Weight trends can hint at water uptake and crop load across a slab or gutter. Plant temperature adds a leaf- or crop-level check against air setpoints that sometimes lie about what the plant actually feels under high radiation or with a wet canopy.

Why climate computers need root-zone context

Controlled-environment agriculture already instruments the air with obsessive care. Watering mistakes and root stress still hide in the slab or pot. Pulling moisture, drain, and plant temperature into Hortimax Plus/Pro lets operators correlate irrigation events with canopy climate without juggling two dashboards—or worse, exporting CSVs at midnight after a wilt scare.

For multi-hectare glasshouses, wireless sensors also cut cabling cost and make seasonal crop turns less of a wiring rebuild. The trade-off, as with any wireless CEA kit, is battery life, radio reliability through wet foliage, and clear ownership of calibration schedules—details GPN’s partnership brief does not fully specify, so ask before you standardize a bay.

Partnership, not a new sensor brand

This is trade-press partnership news: Ridder’s climate platform plus Quantified’s wireless hardware. GPN’s independent report includes company framing but is not a peer-reviewed agronomy study or a yield trial. Expect deployment details—radio range, sensor SKUs, software version requirements, and pricing—to come from Ridder and Quantified sales channels rather than the launch note alone.

Rocks take

A practical CEA integration for growers already on Hortimax who want substrate and plant-temp insights without another orphan cloud portal. Ask vendors for commissioning guides, alarm thresholds, and data-retention behavior before standardizing a whole bay. Source: Greenhouse Product News.
