Bark, the main ingredient of orchid substrates, is steamed at high temperatures. This kills off all the impurities and pathogens. But unfortunately it also
Joost van der Voort (left) and Nadir Laaguili measure the oxygen concentration at the dripper. The system guarantees a level of 10 mg per litre.

Water treatment system maintains optimum oxygen supply

Sufficient oxygen in the root environment is a must for a strong, healthy crop. More oxygen makes the crop stronger and boosts production. That’s
Cultivation fabric

Cultivation fabric with good water permeability and temperature distribution

The improved water permeability was a specific request from users. The fabric is also UV resistant, making it suitable for use anywhere in the
slab

Yields can be increased with new slab

Grodan develops crop-specific product solutions to meet growers’ requirements. Trials have shown that yields can be increased by up to 5% with this new
Biochar is a type of charcoal which looks set to become widely available on the market in future. This product could have potential for horticulture

First tentative steps with biochar turn out positive

Biochar is a type of charcoal which looks set to become widely available on the market in future. This product could have potential for
Controlling the pH helps ensure better nutrient uptake which ultimately leads to consistent growth and production.

Well-balanced root environment ensures good nutrient uptake

When you’re growing green peppers, you have to be extra alert to changes in the growing conditions. Consistent EC levels and good pH control
With a newly developed measurement method, producers of blocking substrate can design new recipes with more predictable properties.

New measurement method makes soil block quality more predictable

Good soil blocks are not easy to make. Besides a good recipe, it’s the experience and skill of the people on the blocking line

EU: ‘Substrate cultivation no longer organic’

Substrate cultivation no longer qualifies as organic. This is the outcome of numerous trialogue meetings between the European Council, the European Commission and the
The Chinese Solar Greenhouse

Good start to cucumber cultivation in Chinese Solar Greenhouse

There are around one million hectares of greenhouses in China. Many of these are so-called ‘’Solar Greenhouses’: greenhouses with a wall that stores solar
Measuring water content in critical layers should become routine at pot plant and bedding plant nurseries.

Water distribution in growing substrates continues to surprise

Contrary to what was assumed in the past, recent research has revealed that water is rarely distributed homogeneously through the root ball following limited
Van den Elzen Plants is hosting a trial with a substrate adapted specifically for strawberries combined with biological supplements.

Adding bio to substrate reduces chemical use in strawberries

The strawberry is a vulnerable crop: the plants and fruits are susceptible to all kinds of diseases and insects. Crop protection is therefore a
