A greenhouse with a pad and fan cooling system will have extractor fans on one wall and on the opposing wall it will have an evaporative wet wall (pad) that lets air in through a fine trickle of water.

The evaporation of the water will cool the air that is being sucked into the greenhouse though the wet wall (pad) and the fans will pull it right through the greenhouse, cooling the entire greenhouse inside.

This is an explanation in its simplest form and there are many factors influencing the effectiveness of pad and fan cooling for example outside humidity, crop length and the distance from the fan to the pad.
