Don't heat them too high
He indicated that the machines are often overheated. "The Frostbuster is heated from 80 to 100 degrees Celsius and the heated air is blown between the trees. The Frostbuster's good results are mainly thanks to the temperature changes that are created and by lowering the air humidity, which means there is less or no frost. It really isn't necessary to raise the temperature in the plot to above critical values. The big advantage of creating temperature swings is that this requires a lot less energy than raising the temperature to above critical temperature values."
It isn't totally clear to some growers. "They believe the temperature is too low sometimes and don't see 'enough' happening due to the evaporation. Their first response is to turn the machine up, but you don't have to. Although we warn them not to turn the machines up it still happens far too often."
