Swamp cooling

When growing indoors in a hot, dry climate, can an evaporative swamp cooler be used effectively or would it be harmful? I use a flood and drain hydroponic system.

A swamp cooler could cool your heat problems. Swamp coolers work by drawing hot dry air through a wet pad. The water evaporates, cooling and humidifying the air. Swamp coolers cool the air for the cost of running a fan rather than an air conditioner.

The drier the air, the more effective the swamp cooler. However, the space should be ventilated so that humidity doesn’t get too high.
