Growing more with less


The global food production system is under pressure. We need to find more sustainable ways of feeding a growing, more urbanised population. ROCKWOOL products enable modern horticulture to increase production while using fewer natural resources.

ROCKWOOL Group collaborated with Wageningen University in the Netherlands to quantify the positive impact of growing tomatoes and cucumbers in Grodan horticultural growing media compared to greenhouse-grown, soil-based crops. The results were significant. For example, Grodan products sold in 2019 resulted in an estimated 100 million litres less water used, equivalent to the drinking water needed to sustain 137,000 people for a year, and covered 29,500 fewer hectares, the equivalent of 85 times Central Park.

In places where agricultural land is scarce, new and innovative forms of food production hold the key to feeding city dwelling populations. Grodan hydroponics can be sited anywhere, including in urban areas that would otherwise be completely unsuitable for traditional soil-based production. For growers, horticulture professionals, and keen gardeners, Grodan is providing efficient, sustainable growing solutions for the future.
