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.

The sharp rise in energy prices is forcing many growers to reduce their lighting, to turn down the thermostat a little and provide screening for longer. If irrigation and nutrient levels are not adjusted accordingly, this can have major consequences for the crop and the roots, warns cultivation advisor Jos Beerens from Grodan.
Part II: Pyrgeometers and glass film technologies: innovations to support the transition to green energy in the greenhouse For the past years, two main challenges have been top of mind for greenhouse operators: labor (shortages and increasing costs) and the ever increasing costs of energy. Andrew Lee, Global Technical Knowledge Manager at Grodan and veteran in the horticultural business, sees these challenges not as limitations, but as important drivers for technological innovation in the sector. In the first part of this series, Lee dives into the latest tech solutions for challenge #2: the transition towards green energy in the greenhouse.

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.
Download report 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.
Download report 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.

Read more 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.

The Dutch horticultural sector binds forces and organizes a full two-day lasting Horticultural program at the Netherlands Pavilion, during the theme-week ‘Food, Agriculture & Livelihoods’ from 17 – 23 February 2022 at the World Expo in Dubai. The first day on Monday 21 February is organized by the public sector and the second day; on Tuesday 22 February is organized by Dutch companies. Grodan, is one of the more than 20 companies that shows how high-tech horticulture can make a sustainable contribution to global food security. The inspiring and interactive program takes place in our price-winning Netherlands Pavilion wherein we combine water, food, and energy. The total program of both Horticultural Days will be broadcast live from the Netherlands Pavilion.
We kicked off the new growing season by a new release in e-Gro. As a result of interviews with top growers worldwide and continuous testing, we’ve increased the focus on optimisation in the Production Module and Reports Module.
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.
According to a recent study, an innovative greenhouse saves more than 75% of required land for vegetable production
