Sustainability plays a prominent role within Grodan, from the manufacture of stone wool substrates to end-of-life solutions. Grodan is founded in 1969 and active in more than seventy countries worldwide. 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.
Benefits of stone wool
The use of stone wool substrate offers many advantages. Thanks to the controlled manufacturing process, this growth medium is of a consistently high quality. The sterile production under extreme temperature ensures that the product is clean and sterile. Its unique hydrophilic fibre also makes the cultivation on stone wool substrate very easy to control. The grower can administer the amount of water and nutrients the crops need in a very directed and controlled manner, to achieve optimal growing results. Waste becomes a thing of the past. Efficient use of water and nutrients keeps yield per square metre high, and energy consumption per unit of product low. Additionally, the product is lightweight, making it easy to use. And last but not least, stone wool can be easily re-used. To sum up, it is a sustainable and environmentally-friendly product.
The combination of the company’s innovative capacity and customer-oriented attitude ensures that the products and services Grodan develops are always up-to-date and guarantee the best possible cultivation performance
The Grodan 6-phase model offers a blueprint for optimal crop results during both each cultivation phase and the entire cultivation period.

Precision Growing enables professional growers to better control important growing parameters and to ensure the optimal growing environment for root development in stone wool. Grodan is the number one of the world in growing media solutions for the professional horticulture industry and has the purpose to “empower Precision Growing for everyone”.
Grodan products are perfectly placed to ensure stainable and safe food production while at the same time directly addressing the issue of water pollution.
More than 100 propagation companies were in the Netherlands this week. They were invited by Grodan - the company organized the International Propagation Seminar for the eighth time. The kick-off of the event took place with a number of presentations, showing how it pays off to grow based on measurements. 'Welcome to Number-land' was the theme of the event.
World Water Day is about focusing attention on the importance of water. Did you know that today 2.1 billion people live without safe drinking water at home? And that the world has committed itself to ensure that everyone has access to safe water by 2030?
Grodan, a member of the ROCKWOOL Group, announced the introduction of its Grodan Prestige stone wool slab. Prestige slabs are ideal for tomato and cucumber growers who want to promote fast initial growth of their crops and vigorous vegetative development in the summer.
It is quite an achievement that GRODAN has been re-awarded the EU Ecolabel certificate for mineral growing media. Strict climate saving criteria on energy consumption and CO2 emissions, for instance, require annual emissions reports and records of electricity consumption of each production plant over the last 5 years. The circular economy is enhanced by a collection/recycling service, and the requirement for mineral growing media to use recycled materials in the manufacturing process.
The growing season is nearing its end, or has already finished. As you have also moved your GroSens or Water Content Meter (WCM) system during this period, our cultivation specialist Gert-Jan Goes has summed up the most important tips.
Hortus in Futuro in Maasbree, a family business that specialises in high-wire cucumbers, has two harvests annually: a winter harvest of the Hi Power variety (planting date: 28 December) and a summer harvest with Hi Force, a mosaic-resistant variety with a planting date around the longest day.
