Grodan offers a crop-specific range of substrate slabs for vegetable growing, specifically for tomato, cucumber, sweet pepper and aubergine crops.
The choice of blocks largely determines the irrigation strategy, which ultimately yields the type of plant required by the grower. Grodan offers a wide range of blocks and plugs that yield uniform plants under various cultivation conditions.
Grodan has a crop-specific range of substrates for floriculture. Our focus is on rose and gerbera. These crops are characterised by their perennial cultivation properties.
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?

Sustainability is in our genes. From the moment we’ve invented stone wool growing we have been facilitating an efficient way of producing food to keep people healthy, with a positive impact on the planet by minimising the use of resources, whilst at the same time helping growers optimise their profit to sustain their businesses in the future.
Data science and AI technologies present us with so many opportunities to collect and mine data in the greenhouse. This paper will help you begin your journey to get the best out of your greenhouse data. There’s a bright future ahead!
Download whitepaper 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.
Download whitepaper 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.
Download whitepaper 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.

Download whitepaper 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.
Download whitepaper 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?
Download whitepaper 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.

Have you ever wondered what happens behind the scenes to ensure that you receive the Grodan products you’ve ordered? Find out by reading a series of interviews with some of the people involved! In this edition, we spoke to Huub Hermus, Key Account Manager Vegetables for the west of the Netherlands.
Crop registration is a key activity in your greenhouse in order to know how your crops are growing, based on this information you can set better your growing strategy and adjust whenever it’s needed. Watch the video’s below to discover more about why crop registration matters and how it’s applied in practice at the Dutch tomato greenhouse company ‘Van Rens’.
Grodan has been working on various recycling trials for several years, an important step when it comes to sustainability. What are the benefits for growers when we use recycled materials in our products, how exactly does it work, and what is involved? Susanne Ruthenberg, Grodan International Product Quality Manager, clarifies these questions in this interview.
Organizations and academics in greenhouse horticulture are continuously looking for new and innovative ways to combat new and existing plant diseases in a natural way. Grodan, led by Peter Spoor, Director of Applications & Development, is currently involved in national and international research initiatives to better understand the role and function of microorganisms in substrates. In this interview, Spoor explains why these studies are so relevant to the sector. “By stimulating and directing microbiological life in the right direction, the plant becomes more resilient and can therefore fight pathogens more easily.”
Grodan supplies innovative and sustainable growing media solutions for professional growers and home gardeners. For almost 50 years our team has been dedicated to creating the optimal environment for roots resulting in healthy and strong plants.

We hope you had a great summer and harvest! As the days get shorter and darker, for many of you the growing season is coming to a close or you will soon transfer to growing with artificial light. We’ve worked hard on new features and updates that are available as of today in your account for growers with lit* cultivation as well as for growers without lit cultivation. As a result of interviews with top growers worldwide and continuous testing, we’ve enhanced three features in order to help you optimize your growing, plan better and gain more insights into your targeted growing strategy.
The way we work today in the greenhouse industry has changed enormously. It has become more common to work remotely and digitally. We see a great demand amongst greenhouse teams and external crop advisors to collaborate on a digital platform, and share and alert each other on key growing information.
Most of you are heading into the busiest period of the year and in order to help you prepare for the peak of the growing season we’ve worked hard on new features which will unburden you and help you focus on doing what you do best: growing!
Four leading players in the indoor farming sector have joined the Resource Innovation Institute (RII) in a pilot that aims to transform the controlled environment agriculture (CEA) sector. The partnership aims to provide growers with insights and benchmarks that they can use to maximize sustainability and minimize their footprint. The pilot is funded by the USDA (United States Department of Agriculture).
Since 2012 Grodan organizes the International Propagation Seminar (IPS). Over the years, this event has become the international platform for propagators and their suppliers to exchange knowledge and offers excellent networking opportunities. In our ambition to further increase the impact of this event we identified new possibilities.
