Grodan offers a crop-specific range of substrate slabs for vegetable growing, specifically for tomato, cucumber, sweet pepper and aubergine crops.
From large, loose tomatoes to a wide range of vine tomatoes. We offer the right slab choice for each variety or growing strategy.
Different varieties and cultivation methods require different cultivation and irrigation strategies. We have the perfect solution!
We developed slab-specific solutions aimed at earlier production, vigorous growth and excellent fruit quality!
Grodan offers the right selection of slabs to optimally steer a strong-growing eggplant crop!
There is increasing demand for hydroponically grown leafy greens such as lettuce and culinary herbs like basil to provide healthier and more sustainable options for consumers.
Vertical farms are a very promising and sustainable solution to the growing needs for healthy, local foods in (over)populated urban areas.
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 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.
Fast and vigorous root development – thanks to rapid and uniform distribution of water and nutrients, and optimal usage of the entire slab volume, especially in the top layer
More direct steering of water and nutrients – thanks to better use of the functionalities of the substrate volume and the greater uniformity within blocks and slabs
More balanced water and nutrient uptake – giving better distribution of finely branched roots in the slab
Optimal control of the EC level in the slab, particularly important during changing weather conditions – thanks to rapid ‘refreshment’ of nutrients
Steering for generative growth – due to better water and nutrient distribution, particularly in the top layer of the substrate
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.

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.

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.

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.
