Care should be taken to maintain the fans well, as well as to maintain the permeability of the pads by avoiding blocking them with salt.
Contribution to energy balance and resource use of greenhouses:
The evaporative cooling lowers the greenhouse temperature and also affects the humidity inside the greenhouse.
...
Another resource which is consumed in large quantities is water, which can pose problems in hot and dry, water-scarce areas where such cooling might typically be required.
Possible steps towards sustainable, energy-efficient greenhouses
To effectively limit the cooling power of the pad-and-fan system to the interior of the greenhouse, rather than cooling the outside air, natural ventilation should be avoided.
