Koidra compared with Hoogendoorn

Hoogendoorn does not sell autonomous growing. It sells Intelligent Algorithms: add-ons to its climate computer, each acting on one part of the climate on its own, from weather forecasts and plant physiology rules. That is semi-autonomous control, a set of separate automations, and none of them reads the state of the crop.

Buying those from the company that sold you the climate computer also ties one to the other. Change the box and you change the brain; run Priva at another site and you run a different strategy there.

Koidra is one control layer that grows the crop, the same on Hoogendoorn, Priva and Ridder alike, including the iSii they stopped selling in January. One way of growing across all your glass.

	Koidra	Hoogendoorn
One system deciding the whole climate	✅	❌ separate add-ons, each on its own
Adapts to the state of the crop	✅	❌ not published
Works on Priva and Ridder as well as Hoogendoorn	✅ one strategy across mixed sites	❌ their hardware only
Simulates the greenhouse climate in full	✅	❌ not published
Simulates the crop inside it	✅	❌ not published
Listens to what your growers register	✅	❌ not published
Crop registration in the product	✅ built for a tablet in the aisle	❌ not published
Beaten expert growers under independent scoring	✅ twice, published by Wageningen	❌
Sells the climate computer itself	❌ we run on yours	✅ IIVO

A ❌ means we found nothing published claiming it, as of September 2026. Hoogendoorn’s Intelligent Algorithms page describes proactive micro-level climate control from weather forecasts, plant physiology and machine learning, sold as separate add-ons, and sets out no crop model, crop simulation, crop registration or any reading of the crop’s state. Absence of a published claim is not proof of absence, and we would rather be corrected than leave this wrong.

Your hardware choice stops deciding your strategy

Buying the control layer from the company that sold you the computer looks simple. The cost shows up later: your growing strategy is tied to a hardware decision, a site running Priva cannot share it, and replacing a climate computer means replacing the brain as well.

The same Koidra strategy runs on Hoogendoorn, Priva and Ridder. A group with mixed equipment gets one way of growing across all of it.

And it models the crop

An algorithm that acts on one part of the climate on its own is automation, not autonomy: nothing in it knows how the crop is doing. Our decisions run on a full simulation of the greenhouse and of the plant inside it, adapting to what your growers register. Two wins at the Autonomous Greenhouse Challenge, scored and published by Wageningen University & Research against expert human growers, are the evidence that it works.

One vendor and one support line is a reasonable thing to want. Koidra is that too, across Hoogendoorn, Priva and Ridder, and the strategy stays yours when the hardware changes.
