A few weeks ago, at approximately 3pm, I was driving past a glasshouse and noticed the internal glass was covered in condensation, not just on the side walls but inside the roof. I’ve previously written, on this site, in regards to the impact on reduction of light penetration that condensation has. I am very interested to know if growers are using anti-condensation coatings and if they are not, why?

It is estimated that up to 8% loss of light is caused by condensation in glasshouse structures and it could cause a staggering light loss of up to 25% in plastic houses!! As condensation is not present 100% of the time, I don’t know if this reduction in light % is throughout the entire day or only when condensation is present. However, in the winter condensation can remain for a long period of time depending on many factors.
There are a few reasons why I think growers are not yet using anticondensation coatings. I don’t believe it is the cost of the anti-condensation products.
