Control the humidity in your greenhouse, it is possible!

Too high humidity in the greenhouse is a daily challenge for the grower.
Certainly in the night hours and early morning when there is a high humidity in the greenhouse due to evaporation of the crop and a limited possibility of ventilation, condensation can occur and an unfavorable microclimate. Certain crops are very sensitive to high humidity. This increases the disease pressure such as fungal growth and botrytis.
Dehumidification in a greenhouse is therefore possible by slightly opening the air vents of the greenhouse, but there are disadvantages to this, such as costly energy loss as a result of a higher pipe temperature, an uneven distribution of the climate and CO₂ loss due to discharge through the air vents. In order to be able to reduce excessively high humidity, whereby the vents remain partially or even completely closed, Holland Heater has launched a dehumidification unit on the market.
These compact units are very easy to install and are available in multiple capacities.
