Cucumber

Cucumber cultivation usually takes place as two or three successive plantings per year, with the precise number depending on the grower's cultivation method and the climate zone in which they are grown.

In addition, seed producers are also developing high-yielding varieties for high-wire cultivation. Different varieties and cultivation methods require different cultivation and irrigation strategies. Grodan supplies specific products for cucumbers that are tailored to the cultivation method and choice of variety.

Innovation through co-creation

What if we could grow cucumbers all year round? At the moment, many cucumbers are still imported from southern countries during the winter months. But the demand for local, reliable production of fruit and vegetables has grown in recent years.

Strawberry whitepaper mock-up — The opportunities of indoor strawberry cultivation
Global strawberry cultivation is at a turning point. Growers are faced with sharp cost increases, while they also need to continue to guarantee high quality and consistent products, as consumers demand healthy, fresh fruits throughout the year. That is why commercial strawberry propagators and growers are constantly looking for ways to optimise their growth strategy, maximise their yields and minimise their costs.

Mock-up strawberry whitepaper higher value is here — Whitepaper: Higher value is here
A recent trial by Grodan has demonstrated that strawberries can be propagated and cultivated on a stone wool substrate while maintaining high quality and attractive fruit size. Additionally, the yields and Brix values were higher than with traditional methods.

e-Gro — The start of data driven growing
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.

visual, whitepaper, TTL campaign, EC — Monitoring nutrient balance, pH & EC in the root zone
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.

visual, whitepaper, TTL, EC — Improving tomato fruit quality
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.

Grodan, visual, whitepaper, TTL, campaign — Irrigating in changing weather conditions with minimal drain volumes
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?

Whitepaper, Grodan — Switch to Clean
Hydroponic lettuce and other leafy greens will soon start to dominate sales at supermarkets and chain restaurants. With up to 12 times the number of crops a year than from open fields and twice the crop density, no other production method can compete. Production environments must however be clean. Stone wool is both clean and inert, making it ideal for producing hydroponic lettuce and other leafy greens.
