Solution in sight for light loss due to condensation on glass
27-08-2015The 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.

ReduFuse produces more growth in generative crops
06-05-2015Diffuse light can contribute towards a better fruit quality and higher production. It’s mostly these results that are mentioned when research has been carried out on diffuse light through glass, a coating or a screen. What the research also shows, but where less attention has been paid up to now, is...

Cleaning greenhouses with fluoride based agents
30-05-2014The horticultural sector often uses a cleaning agent based on fluoride to clean glass. Fluoride chemically cleans the surface of the glass. Several minutes after application the treated glass along with the dirt is rinsed off. But this principle should not be applied to synthetic greenhouse roof coverings.
