“There are many benefits to using DryGair. First of all, reducing humidity. Second, is the prevention of wet leaves. When the leaves aren’t wet in the morning, it allows us to maximize our work hours in the greenhouse. We aren’t limited in our use of manpower.

One of the targets we set when we integrated DryGair, is to reduce our environmental impact and pesticide use. Of course, as DryGair does what it’s meant to do, we hardly use pesticides anymore. Rather, we use preventative products, at a significantly lower rate than before.

I forgot to mention energy. Ventilation involves removing high-energy air from the greenhouse and introducing low-energy air. This process is extremely wasteful in terms of energy. DryGair helps us save this energy as well.”

“Previously, our rooted cuttings could get wet in the morning, especially in winter and early spring; Causing Botrytis. The DryGair units now remove the moisture from the air; Relative humidity remains beautifully around 75% day and night. Because the fans continue to run, a uniform and active climate is also created, which is reflected in the quality of the crop.  We recently purchased a 2nd unit, after having gained 2 years of experience. If something is right, the product sells itself.”

Rooted Cuttings Grower, The Netherlands

“By using the DryGair units at our nursery, the screens remain 100% closed. This leads to a uniform climate. No cold corners and no dripping through the screen gap. The gas savings rose to 50% in the winter months. We started with 4 units; now a total of 10 pieces are running.”

Leen Weerheim (nursery de Zuidplas)

“We did the experiment with DryGair to control Botrytis, which we did. There was almost no Botrytis. We didn’t expect to also get 25% increase in yield.”

Syngenta, Seedless Peppers

We will see better growth to the plant because it can take up nutrients. There’s suddenly room for the plant to evaporate moisture and that will take care of getting more fruits and be more productive”

Peppers Grower, New Zealand

“In the cultivation of Strelitzia in the winter months, we suffer from mold problems due to very high relative humidity. We now have several years of experience with DryGair in a growing area of 5,700 m. Qualitatively we have achieved our goal! DryGair exceeded our expectations due to the additional benefit of energy savings; We have saved 54% on gas consumption compared to the previous years”.
