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!

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.

Grodan has operated in the Russian market for more than 20 years. It’s a challenging market where growers have to deal with a changing climate and decreasing natural resources, while consumers increasingly demand fresh products. How can an international organization like Grodan stay in close contact with growers and thrive in such a country of extremes? And what can we do to help growers shift towards a circular economy? We posed these questions to Aleksey Kurenin, Business Manager RSM (Russian Speaking Markets) at Grodan.
Vertical farming is on the rise around the world, not least because it supports a number of major societal trends such as local sourcing and sustainability. In this article, Tico van Leeuwen explains why the right growing medium plays an important part in creating the optimal conditions for a strong and healthy crop, and why stone wool is such a good choice for vertical farmers.
In october last year, right before the dark winter months, ten parties from the greenhouse horticulture sector started growing cucumbers at the Botany research center in the Netherlands, as we learned during the first episode of this cucumber trial. These parties came together to investigate how cucumbers can be cultivated in a sustainable and efficient way during winter, with the help of extra (LED) lighting.
As one of the defining systems builders in the horticulture industry based in Horst (the Netherlands) founder and CEO of Light4food Rene van Haeff was convinced that the horizontal and vertical controlled growing systems in combination with light were to be the future solution for growing crops sustainably. Light4Food is a turnkey system builder for a wide variety of crops grown in both greenhouses and vertical farms.

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.
Did you know that for 99,7% of the high-tech growers in greenhouses, biological control methods are the standard? To protect their plants against harmful insects, per hectare 511.000 natural enemies of these insects are used per year.
During the past winter season, Grodan together with nine other partners was involved in a cucumber trial at Botany. We investigated what effect different light recipes have on the cultivation of cucumbers in the greenhouse. The goal: growing cucumbers indoors throughout the whole year in the most sustainable, efficient way.
As we’ve entered the spring season, the harvest season will start soon for many growers. The e-Gro team recently launched a new product release with new features which will help growers providing more insights during the busy harvest season. We’re very excited to share with you the latest improvements in the Dashboard Module.
On World Water Day, we highlight three solutions that are currently being explored to optimize water usage in the greenhouse.
