Rufepa considers the fans a key factor to get an homogeneus and stable climate inside of the greenhouse.
Why?, the reason is simple, a good ventilation and air circulation inside of the greenhouse will provide the plant a balanced distribution of air, so CO2 will be equal for all the plants and we avoid excess of humidity in some part of the production unit.
The amount of fans and its capacity per greenhouse is calculated by our engineering department analyzing the weather conditions, crop to be produce, volume of air in the greenhosue and the ideal changes of air per hour.
