What is AntiCondens?

Condensation droplets on the inside of greenhouse windows are a nuisance. All those droplets together can cause light loss. What’s more, when droplets fall on the crop the disease pressure rises. AntiCondens is the solution to avoiding these problems. Once dried, this product creates a hydrophilic layer that causes condensation to run off the surface, thus preventing the formation of water droplets. This provides up to 5% additional light and prevents damage and diseases.


  • AntiCondens can Improved transmission increases yield and saves energy
  • Two versions: for greenhouse glass and plastic film
  • Water-based, safe to use
  • AntiCondens lasts the entire season

More light = more production

Over the course of the year, for about half the time the glass is wet with condensation. This causes light loss. Researchers at Wageningen University have found that the way the condensation forms on glass and plastic makes a big difference to the amount of light lost. Droplets cause serious light loss, while a thin, even layer of condensation can actually increase light ingress. In addition, research shows that the formation of condensation droplets reduces light transmission through ordinary horticultural glass by 5%. This is a particular problem during the low light months, resulting in loss of production. As a rule of thumb, 1% more light produces 1% more production.

How to use it

AntiCondens is available in two versions: one for use on glass and one for plastic. Both versions come in a 20 litre can. AntiCondens should be applied on a clean, dry surface free of other substances. For one hectare (2.5 acres), mix 60 litres (15 US gallons) of AntiCondens with 1,000 litres (264 US gallons) of clean water. Apply AntiCondens from the gutter to the top of the ridge with a fine mist until the surface is entirely moistened. After application, allow the treated surface to dry thoroughly. You can speed up the drying process by keeping the greenhouse well ventilated. If applied well, AntiCondens will remain active the entire season.


  • AntiCondens should ideally be applied when the greenhouse is empty.
  • If applying above the crop, test for phytotoxicity. Spray a small amount of diluted AntiCondens on the crop and check for any negative effects before starting application.
