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.
Optimal use of the total substrate volume throughout the entire cultivation period.
Substrates to facilitate quick rooting and fast early growth. Ideal for whatever you needs are!

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.

Starting a new crop is always an interesting time of year. It’s an eagerly awaited fresh start however some decisions and actions we make now can have a big impact later in the cultivation.

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.

Maintaining a good nutrient balance in the root zone can help avoid many common fruit quality disorders. Standard feed recipes are available from all analytical laboratories and with a regular analysis of the root zone solution the feed solution can be adjusted so that optimum nutrient ratios are maintained.

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.

According to the United Nations (UN), water is the primary medium through which we will experience the effects of climate change1. Water availability is becoming less predictable in many places, and increased incidences of flooding threaten to destroy or contaminate sources of water, and water sanitation facilities.

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.

According to Jack van Schie, head grower at one of the company’s three locations, the combination of this slab with both the Plantop block and the GroSens sensors gives him more certainty that he will achieve the high quality that customers expect.
