About the system

Precision-grown for peak performance

Built on years of expertise, Gronos is a fully automated, turnkey solution that optimizes every step of the growing process. Advanced climate control ensures ideal conditions, while custom NFT gutters provide the perfect plant support. Before harvest, support sticks are automatically removed, and a dedicated machine picks the loose cherry tomatoes—no human hands required.

About the plant

Built for automation

We’ve redefined tomato cultivation by developing a plant that thrives in a fully automated environment. After years of research and collaboration between agronomists, R&D specialists, and seed breeders, we created a compact plant that grows from seed to harvest in just 15 weeks.

Minimal intervention needed: No pruning, no training—just efficient growth.
Compact & mobile: Plants reach only 40 cm in height, making them easy to transport through different growth phases.
Lower pest & disease risk: Short cycles reduce exposure, keeping crops healthy and productive.

Unique elements

Every element of Gronos has been engineered through strong collaboration between our many departments within Certhon:

Automation at its core

From sowing and transplanting to spacing and harvesting, Gronos does it all—fully automated. Robots and smart systems move crops through the greenhouse, maximizing efficiency.

Smart water management

Gronos integrates advanced water evaporation technology, reducing resource use while ensuring optimal growing conditions.

Flexibility with short cycles

With a 15-week crop cycle, growers can quickly adapt to market trends and even switch tomato varieties multiple times a year—offering fresh produce that aligns with seasonal demand.

A special collaboration

Gronos is the result of an intense collaboration between lots of highly-skilled people, all extremely knowledgeable in their own expertise. A unique partnership in seed breeding and development, together with technology. That's the only way Gronos was made possible.
