Strawberry trial at Delphy ISFC with Limgroup (Limore One seeds) 2025

The trial began on 14th January 2025 and will be concluded by the end of October, with production taking place at Delphy ISFC. Throughout the trial, the partners collaborated closely with researchers to develop precision cultivation strategies that ensured optimal plant development. By combining crop steering, data-driven monitoring, Limgroup’s advanced strawberry genetics (variety: Limore One), and Grodan’s high-performance stone wool substrate, the team created ideal growing conditions for consistent, high-quality results.

Summary of mid-year results based on full LEDs, precision irrigation and active air dehumidification 

Philips toplighting plus interlighting is on track to deliver 5-7% yield increase
Low-nitrate strategy supports generative plant steering 
Adjusted potassium/nitrate ratios potentially lead to a reduction in blotchy ripening (green spots)
Fine-tuning of screening, heating and lighting strategies delivers additional energy savings

The consortium is organized and managed by Cultivators, together with the Proefstation voor de Groenteteelt (PSKW) in Belgium, one of Europe's leading applied horticultural research centers. It unites key technology leaders, breeders, and system specialists, including Rijk Zwaan, Enza Zaden, Hortiplan, Signify, and Ellepot, combining expertise across genetics, lighting, substrates, systems engineering, climate, and irrigation. Supporting partners include LetsGrow.com, Ammerlaan Construction, Svensson, Roam Technology, JB Group, and Delgeco

Precision starts in the root zone
In high-tech cultivation, performance depends on how precisely the root zone can be controlled. Grodan growing media provides a uniform and reliable foundation that allows growers to steer water and nutrients with confidence.

Because of its high level of uniformity, stone wool allows growers to focus on crop strategy rather than compensating for inconsistencies.
