More than 50 years ago, we noticed a tiny plant growing in a piece of abandoned stone wool on a building site. Just as it's designed to do, nature had found a way to grow. And it inspired us to design a system to support it – a smarter, soilless way of growing that we evolve, explore and refine continuously. A system that promises high yields of consistent, high-quality fresh food and medicinal crops to feed and treat the world's growing population.
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.

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.

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.

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.

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.

Vertical farms are a very promising and sustainable solution to the growing needs for healthy, local foods in (over)populated urban areas. What’s more, at Grodan, we believe vertical farms will play an indispensable role in our future global food production. So, what is it all about?
Global strawberry cultivation is at a turning point. Growers are faced with sharp cost increases, while they also need to continue to guarantee high quality and consistent products, as consumers demand healthy, fresh fruits throughout the year. That is why strawberry propagators and growers are constantly looking for ways to optimise their growth strategy, maximise their yields and minimise their costs.
A recent trial by Grodan has demonstrated that strawberries can be propagated and cultivated on a stone wool substrate while maintaining high quality and attractive fruit size. Additionally, the yields and Brix values were higher than with traditional methods.

High-tech greenhouse horticulture is preparing for a new, global transition to data-driven growing practices. In Horticulture 4.0, countless sensors and measuring systems collect a constant flow of data on growth conditions and the functioning of crops, from both visible parts of the plants as well as in the root zone environment. These multiple data flows and their correlation are analysed centrally and translated real-time into setpoints using sophisticated growth models and smart, self-learning software. The recommendations can be used to maximise the expected operating results. This is the ultimate form of Precision Growing.

In today’s conditions, growing crops can be likened to performing sport at elite level. Green fingers and a passion for growing no longer guarantee good operating results. The goalposts are constantly being shifted. Stringent environmental regulations and legislation, excessive demands placed by customers, fierce competition and small margins force growers to maximise the potential of their crops efficiently and sustainably. At the same time, the continuing trend of upscaling, the tight labour market (smaller pool of available labour) and dwindling numbers of experienced crop managers (vanishing expertise) are all obstacles along the path of achieving business continuity and success. Not just today, but also tomorrow and in the years ahead.

The composition of the nutrient solution should be appropriate to the needs of the crop. One of the benefits of using Grodan stone wool substrates is that the nutrient composition is under total control of growers. However the uptake of particular nutrients varies constantly with growth and fruit load therefore the nutrient balance, pH and EC in the root zone is also constantly changing.

Have you ever wondered why at certain times of the year tomato crops are more susceptible to fruit quality disorders? For the most common physiological disorders namely blossom end rot (BER) and uneven colour (blotchy ripening) this whitepaper explains their cause and prescribes simple solutions to avoid / minimise risk of symptom expression in the first place.

The volume of irrigation water applied per square meter is linked to radiation sum as a general rule in the ratio 3.0 ml per joule. The exact figure will ultimately depend on outside weather influences such as wind speed, humidity as well as the greenhouse vent position. The question is whether this total drain volume is necessary or not? So what is the role of drain and what is a sufficient volume of the drain?

Maintaining a good nutrient balance along with a well-executed irrigation strategy can help to avoid many of the common fruit quality disorders which are experienced over summer. Standard feed recipes are available from all analytical laboratories and it is important that you take samples of water from within the slab on a regular basis so that the feed solution can be adjusted in order to maintain the correct nutrient ratios throughout the summer.

Hydroponic lettuce and other leafy greens will soon start to dominate sales at supermarkets and chain restaurants. With up to 12 times the number of crops a year than from open fields and twice the crop density, no other production method can compete. Production environments must however be clean. Stone wool is both clean and inert, making it ideal for producing hydroponic lettuce and other leafy greens.
The electrical conductivity (EC) unit is commonly employed for analyzing fertilizer component concentrations in hydroponic growth’s nutrient solution or root zone. This involves measuring the electrical conductivity of a solution to determine the cumulative ions necessary for plants (e.g., NO3-, Fe3+) and ballast components (e.g., Na+). The EC value is usually expressed in either millisimens (mS/cm) or microsimens (µS/cm).
Caté, the renowned applied research station in Saint Pol de Léon, situated at the heart of Brittany’s thriving vegetable and horticultural region, has concluded a series of comprehensive comparative trials focusing on stonewool and coco growing media for soilless tomato cultivation. The trials, spanning multiple seasons, have yielded remarkable insights into the agronomic, environmental, and economic advantages of these two media.
As the world's population continues to grow, natural resources are becoming increasingly scarce. Let’s have a look at opportunities to ensure plentiful, healthy food production and availability.
Traditionally, the spring season has always been the prime time for strawberries. Particularly when grown outdoors. But there is more and more proof that global strawberry cultivation is at a turning point. The latest step is to start cultivating year-round, possibly providing fresh produce in the midst of winter.
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.
