Relative to growing in soil-based systems, Grodan products sold in 2021 resulted in an estimated 111 million litres less water used. Grodan products also saved more than 32,000 hectares of land, an area more than three times the size of Paris.

Sustainable food production

Researchers at the Wageningen University in the Netherlands estimate that by 2050, the world will have to produce twice the amount of food using half the resources compared to today1[1] - all while dealing with climate change-related threats to food security[2].

Growing systems using Grodan play an important role in overcoming these challenges. Research carried out by Wageningen University shows that high-tech greenhouses have the biggest positive impact on the UN Sustainable Development Goals compared with all other growing systems and score highest within water and nutrient efficiency[3].

Professional growers use Grodan to produce fresh vegetables in a highly efficient way, using less water, fertiliser, and pesticides than soil-based solutions. Food produced on Grodan growing media uses 53 percent less water, while achieving 76 percent more yield – and it requires far less land, meaning it can be produced locally, reducing transportation.
