Light colour and intensity affect biological balance
02-05-2016Both pests and their natural enemies respond to the colour and intensity of light. This means that coatings can affect the biological balance in greenhouses.

Measuring crop temperatures
30-04-2016In greenhouse cultivation, we normally measure the greenhouse temperature. However, the temperatures of the plant and fruit are also very important in achieving optimum production and quality.

Diffuse light for Gerbera
29-04-2016Gerbera is a light sensitive crop that benefits from high sums of light. However, during the summer months, too much light can damage both growth and quality. Therefore gerbera crops always need to be protected. This can be achieved by using a coating, screen or a combination of both. In practice, we...

ReduHeat or ReduFlex Blue?
28-04-2016The arrival of photoselective coatings on the market has allowed more crop specific light to be offered to the plant. ReduHeat is the first photoselective coating that has been specially developed for horticulture. Many growers want to keep heat out of the greenhouse but aren’t prepared to sacrifice...

Sweet peppers benefit from diffuse light
30-03-2016Light is an important factor for achieving high yield and quality in a sweet pepper crop. Not only is the amount of light crucial, also its distribution during the day. Furthermore, the quality of the light, such as light colour and whether or not it’s direct or indirect is significant.

Uniform coating is an art
08-03-2016An evenly applied coating is very important. Otherwise an uneven amount of light enters the greenhouse and that can result in a non-uniform crop or problems with the climate control. Gert-Jan van Hattem, of spraying specialist HPW Spuittechnieken, talks about the art of coating.

How does AntiReflect work?
11-01-2016AntiReflect reduces the difference in refractive index between air and glass; that is why the greenhouse receives more sunlight.

Anti-condensation coating for glass
11-01-2016In 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.

Attention to clean glass rewarded with gain in light
28-10-2015In vegetable production the old rule of thumb still applies: 1% more light = 1% more yield. For this reason, dirty glass is not desirable.

Light distribution in the greenhouse
28-10-2015It is difficult in the greenhouse to measure light well. Certainly on clear days, shadows thrown by parts of the building cause a large difference in the light that falls upon the crop.

Use temperature and light to steer respiration
28-10-2015The plant performs three types of respiration. Of these, maintenance respiration offers growers the most opportunities to steer the crop, of which the most valuable way is ‘Grow based on light’.
