How it started

Producing more with less is in our roots. Since we invented hydroponic stone wool growing in 1969 we have continuously evolved the Grodan approach to sustainable growing. Our first customers started growing hydroponically to avoid disinfection of the soil which was done with methyl bromide, a heavy toxic chemical. Our growing media enabled them to provide the plants with water and fertilizer much more precisely and efficiently. By doing so the yield per square meter further increased, while at the same time saving water, fertiliser and subsequently saving on costs. Grodan can be seen as one of the Founding Fathers of Precision Growing for the horticulture industry. Today,growers make use of a wide range of innovative products for the entire growing cycle from the start of propagation till harvesting.

Grodan and Signify collaborate to conduct low-energy tomato cultivation research with an expected savings on heat-input up to 40%

The trial started September 2023 at Botany and will explore principles of low energy growing under fully dimmable Philips LED lights. Focus will be on plant transpiration and nutrient uptake in a 260 m2 department fitted with active air de-humidification. This year's strategy is built on the knowledge gained from last year's successful tomato trial by Signify. By modelling the expected crop development and performance, both Grodan and Signify expect to reduce up to 40% on heat input by dimming the lights based on crop needs, energy prices, and outside light conditions.
