Answer to Question 1

If more cold air enters through the louvers than can be picked up by the
pressurizing fans the excess will settle to the floor at the inlet end of the
greenhouse. This would result in an uneven growing temperature.

Answer to Question 2

1) It can be used in place of a mist system in a cutting propagation
greenhouse. 2) It can be used to maintain high humidity in a seed propagation
chamber to get around the deleterious need for watering.
