Horticulture Principles and Practices

crosswise (Figure 12–19). The benches are shorter and aisles numerous. Although the
aisle space significantly reduces the usable area of the greenhouse, movement around
the greenhouse is easier with this arrangement.
Peninsula Arrangement
The difference between the peninsula arrangement and cross-benching is the presence of
a primary central aisle in the former that runs the entire length of the greenhouse. The
primary aisle in cross-benching runs along the wall (Figure 12–20).
Movable Benches
Movable benches are especially popular container production enterprises. To maximize
the use of space, some greenhouse designs include movable benches and one aisle. When
work on one bench is completed, the bench is mechanically moved so that work can be
completed on the next bench (Figure 12–21).
Pyramid Bench
A pyramid bench is an arrangement in which benches are placed in tiers. It is an ideal
configuration for hanging basket production.
Whether concrete bins or raised benches are used, the layout is important. As previously
indicated, aisles must be made to allow equipment to be moved around and to provide
working room around the bench while maximizing the use of floor space. In greenhouses
designed especially for cut flower production, the ground bed may run the full length of the
facility. Designs for nutriculture usually have special designs to accommodate the special
equipment they require.
