Sugar transport through membrane

Ingenious transport system brings sugars from ‘source’ to ‘sink’...

Photosynthesis takes place in the leaves but the products that are made – sugars – have to be transferred to other parts of the
Wim Voogt: “We haven’t seen any negative impacts of high sodium concentrations in sweet pepper.”

Split-root system harvests sodium and removes it via the crop

The shift towards closed growing systems is forcing growers to take a critical look at their sodium figures. Would higher sodium levels affect the

Toine Overgaag: “Growing a new crop is a challenging opportunity. But we now produce some 2.8 million plants annually and rank among the top three growers in the western US.”

Westerlay Orchids evolves into major player in orchids in USA

At the end of the 1970s, the Overgaag family, with a background in vegetable growing, emigrated from the Netherlands to California to start a
In the Ter Laak Orchids trial greenhouses, the researchers compare the quality of the varieties Sacramento, Donau, Jewel and Las Palmas grown with standard lighting and a dimming treatment.

Limits of dimming lights in phalaenopsis reached

Intensive lighting in winter is common in Phalaenopsis growing. A long-running Dutch research project is seeking to answer the question of whether less lighting

“It works, but you need discipline to succeed”

Thrips are one of the biggest threats chrysanthemum growers face. But this hasn’t put off River Flowers in the central Dutch town of Zaltbommel:
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
Damage caused by an excess of manganese and zinc is the result of too much trace element fertilisation combined with a sharply declining pH.

More measuring and timely tweaks keep pH and crop in balance

Growing media must allow plants to develop healthily all the way from the potting area to the living room. The correct acidity or alkalinity

Online software for energy-efficient greenhouses

Hortinergy is an online software package for designing energy-efficient greenhouses by simulating energy consumption and comparing technical solutions. Energy is a major expense in
Paul and Marcel van den Broek: “The more even climate plus the longer screening can result in 10 per cent energy savings per kilo of product.”

“I get goose bumps from such evenly coloured tomatoes”

The air above an energy screen is much drier than that below it. Currently around 20 companies in The Netherlands are making use of
Stefan Bakker, here at Ter Laak Orchids in Wateringen: “Choose your sources wisely and keep the best quality irrigation water for the summer period.”

Knowing where and how water contamination can occur is key

Dutch greenhouse growers manage their water flows and emissions into the environment very well compared to those in some other countries. But they could

Greenhouse growers across the world must focus on water

Water. It’s essential for everything that grows and blooms anywhere in the world. And of course greenhouse horticulture is no exception. But with the
Manufacturers offer a wide range of glass types. The question is how growers are supposed to choose if they don’t have enough data on their own crops.

“Sharing crop data helps build knowledge on diffuse roof”

Diffuse glass is becoming routine in new build greenhouses – and much more quickly than anticipated. But it is still difficult for growers to
