Range Orientation

1. Orient the range to allow for maximum light intensity to enter the greenhouse.
   
   
2. Know the direction of the prevailing winds to orient the greenhouse to minimize heat loss. See Figure 13.6.

3. Entrances and drives should be accessible to large trucks, customers and employees.

Bench Orientation in the Greenhouse

1. Common bench arrangements are as follows and shown in Figure 13.7:
   
   
   1. Longitudinal - Typically used for fresh flower production. This type arrangement allows for mechanization, but it is difficult for employees to move across the greenhouse.
      
      
   2. Cross benching - Provides for easy accessibility to all benches but does not maximize growing space.
      
      
   3. Peninsular - Provides accessibility by employees, while maximizing the growing area.

** Movable benches allow the grower to change the bench arrangement as needed. Figure 13.8 shows an example of a movable bench.
