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.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
