Know-how

Mardenkro’s ReduSystems products are global leaders when it comes to regulating greenhouse climate. For many years ReduSystems has been at the forefront of innovation. In 2004 ReduHeat won the Horti Fair Innovation Award.

In 2011 an international expert jury judged ReduFuse to be the most innovative product at the exhibition, so once again we went home with the Innovation Award. We can’t innovate just by ourselves. Together with worldwide leading research centres, universities and growers, we continuously develop new products and test them in practice. Only products with proven added value are included in the ReduSystems family.



Grower Van Paassen: "light gain in greenhouse after applying AntiCondens leads to more production”

Grower Van Paassen:

For crops that are switched in the summer, this is the ideal time to apply AntiCondens to the inside of the greenhouse cover. It is a good preparation for the coming humid season, when condensation droplets block valuable light. Tomato grower Paul van Paassen has been using AntiCondens for three years, realising a light gain of 7 to 9 percent.

Every percent can be converted into higher production. Mardenkro offers a package of solutions designed to improve the incidence of light into a greenhouse by as much as ten percent.

Light is the limiting factor in production in winter. Every step taken to improve light ingress is therefore welcome.  > Read more about increasing light ingress in winter

Vegetable and ornamental crops can produce much more than they do at present if the climate conditions are always ideal.

Preventing light loss and disease in plastic greenhouses

Preventing light loss and disease in plastic greenhouses

Condensation on the greenhouse roof is the result of air dehumidification. In plastic greenhouses steps need to be taken to prevent the condensation from causing problems.

Tomato grower Paul van Paassen is the first in the Netherlands to use the coating AntiCondens for glass. “It clearly leads to more light inside,” he says.

In the Netherlands the levels of light are low in winter. We can compensate for this by using additional lighting, but it is also important to let in as much of the available natural light as possible. One way of getting more light in is to reduce light loss caused by condensation.

The crop continually transpires. This leads to condensation on the glass roof. On one hand this is positive as it dehumidifies the greenhouse but on the other hand the condensation inhibits light entering. But a solution is in sight for the latter.

Incoming light in winter certainly can be improved

During the winter natural light is the limiting factor for growth and production: Every reason to look at optimising the light entering the greenhouse during the winter. Frank Kempkes of Wageningen UR Greenhouse Horticulture thinks it’s possible to improve it by 15-20%.

Water droplets on the inside of greenhouses due to condensation can cause considerable loss of light.
