Marathon runners tend to get in trouble in hot, dry weather. Insufficiently humid air is especially fatal. The same applies to plants. When it is too dry, plants put on the brakes. High-pressure misting keeps the plants going, and so the temperature may even rise a little. In greenhouse horticulture, the statement 'humid air contains more energy than dry air' is universally known. This is due to the fact that evaporation requires energy. This is not only true for mist introduced by humidification, but also for transpiration by the plants. As long as the energy balance in the greenhouse and in the plants is taken into consideration during misting, plants will not become 'lazy'.
