About Grodan

Designed to grow

Designed to grow; Grodan is the global leader in supplying soilless rootzone management solutions for Controlled Environment Agriculture. These solutions are applied to the cultivation of vegetables and flowers such as tomatoes, cucumbers, sweet peppers, eggplants, roses and gerberas.

At Grodan, we aim to help feed and treat the world’s growing population by innovating solutions from our stone wool growing media to enable ‘more-with-less’ growing. Through the method known as out-of-soil, our stone wool substrates, sensor systems, software and expertise support the reliable, informed growing of healthy, fresh, high quality produce. Our material is 100% recyclable, and supports growing methods that use up to 50% less water, 20% less chemical plant protection products and 75% less land. Sustainability plays a prominent role within Grodan, from manufacturing stone wool substrates to recycling solutions and services.

Grodan has more than 50 years of cultivation experience. We pioneered the development of hydroponic growing methods in the 1960s, and today, our soilless rootzone management solutions are used in large-scale commercial greenhouses and indoor facilities in over 70 countries across the globe. The head office is located in Roermond, the Netherlands.

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.

Designed to grow sustainably

The substrate we have innovated to support soilless growing is made of stone wool – a clean and recyclable material formed of natural, abundant basalt rock. It's thanks to this material that soilless growing places minimal strain on our world's precious resources, using up to 20% less fertiliser, 50% less water and 75% less land that can be given back to nature to rest and rewild.

Designed to grow from root to fruit

Growing crops, produce and plants soillessly means growing them reliably. Because both the conditions and the stone wool substrate they're grown in are reliable. Every decision made in the greenhouse today has a major impact on tomorrow's results. We support our deeply-rooted knowledge with our digital solutions to improve cultivation from root to fruit.

Designed to grow anywhere, anytime

As the world's population continues to grow, so too does the need for healthy, fresh food and medicinal crops. Since our soilless way of growing isn't dependent on season or location, it can be done anywhere, anytime, meaning it's reliable and consistent – and high yields can be readily available whenever and wherever they're needed.

Designed to grow for biodiversity

Since our way of growing is soilless, it supports the human world without depleting the natural one. Using up to 50% less water and 75% less land, higher yields can be reliably achieved with a much smaller physical footprint. Meaning more land can be given back to nature to rest and rewild.

Designed to grow with less water

Whatever the crop, our way of growing protects diminishing water supplies. While nothing can thrive without water, soilless growing allows plants to do so with up to 50% less of it than soil-based cultivation. And the water it does use is recycled and reused – as are the nutrients within it.

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.

Growing media and the efficient use of nutrients

One of the 15 global challenges formulated by the Millenium project is “How can population growth and resources be brought into balance?“ One aspect of this challenge is improving the use efficiency of the global resources e.g. nutrients. These nutrients are just as important to agriculture as water.

How growing media have an impact on feeding a growing population

World population is expected to grow another 1 billion in just 12 years, and reaching 9 billion people in 2050, creating unprecedented demand for food, and hence agricultural land. To keep up with population and economic growth, food production should increase by 70% by 2050.

Using less water when growing hydroponically

Water scarcity is one of the global challenges. The problem of water scarcity is a growing one. Water use has been growing at more than twice the rate of population increase in the last century. Food and agriculture are the largest consumers of water. As more people put ever increasing demands on limited supplies, the cost and effort to build or even maintain access to water will increase.

How soilless growing has an effect on less water pollution

One of the 15 global challenges defined by the Millenium project is ‘clean water’. The UN-water (2010) statement contains the following text: “As a global community, we must refocus our attention on improving and preserving the quality of our water, a challenge that requires bold steps internationally, nationally, and locally. Directing global priorities, funding, and policies to improve water quality can ensure that our water resources can once again become a source of life.
