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.
In many regions across the globe life is getting back to normal step by step but many hurdles will remain. Whatever the situation we at Grodan have our channels open to make sure business can continue. To stress our readiness to assist we have made this video message for you! Let's keep the horticultural chain running together!
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.
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.

His official title is Product Lifecycle Manager Grodan, North America. Although his colleagues often refer Yianni Monahan as “the recycling guru from New York”’. He speaks about the transition of the horticulture industry towards a circular economy and the important role recycling plays in this. ‘We truly believe this is THE CHALLENGE for the next generation and we want to help lead the endeavour for a solution.’
Read what you as a grower need to know about Grodan’s thoughts and actions around the use of (biodegradable) plastics or the films surrounding the products.
Did you know that technologies used in space science can also be used in high tech greenhouses? Our partner Rasit Abay is currently exploring how imaging technology can be used for crop registration and yield prediction.
Founded in 2010, Dutch cucumber production company Jevero BV has a 3-hectare greenhouse where it grows high-quality cucumbers that are sold in the Netherlands, the UK, Germany and beyond. In early 2019, co-owner and crop manager Jeroen Geven switched from the Grodan Master stonewool substrate to the Grodan Prestige. Now that his second season of using the new slab is underway, we spoke to him to hear about his experiences so far.
Hydroponic cultivation on stone wool growing media results in a higher yield per square meter compared to cultivation in soil. In a greenhouse the ultimate climate conditions can be created for plants. This, in combination with Precision Growing, enables growers to give the plant exactly the amount of water and fertiliser it needs. This leads to a strong plant that carries more fruits.
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.
Read more Since we invented hydroponic stone wool growing in 1969 we have continuously evolved the Grodan approach to sustainable growing.
Read more Precision Growing enables professional growers to better control important growing parameters and to ensure the optimal growing environment for root development in stone wool. Grodan is the number one global provider of growing media solutions for the professional horticulture industry, exemplifying our purpose to “empower precision growing for everyone”.

According to the WHO, unsafe food causes over 200 illnesses around the globe, from diarrhea to cancer. Food can become unsafe when it is exposed to harmful bacteria, viruses, parasites or chemicals. Over the last few years our food-chain has become increasingly complex, with different players and global distribution.
Grodan, part of the ROCKWOOL Group, received the extension of its EU Ecolabel until 2022. After being awarded the EU Ecolabel in 2019, a yearly audit is part of the well-respected certification scheme. This makes Grodan the only eco-labelled stone wool growing media available to professional horticulture growers.
The global spread of covid-19 is a challenge unlike anything seen in our lifetimes. At Grodan we’ve always been optimistic that we will come through this difficult crisis as strong as ever. Therefore, it is good to experience that situations in the various regions are getting back to normal. Slowly but surely.
Due to the Corona situation, physical visits are, unfortunately, no longer possible. However, if you have questions and/or comments, our Account Managers and Customer Service employees are available for you. Recently, they have further increased their digital skills and have good experiences with support over the phone and online like Skype and Microsoft Teams.
True to our crisis management motto, Be the ROCK, we are determined to weather this storm; we will stand by our people, customers and external stakeholders.
Data-driven decisions are becoming increasingly important in horticulture. This was evident at Horticontact 2020, where Grodan was present.
