The wire fabric mesh should be 1″ x 2″ 14 gauge or 2″ x 4″ 12 gauge galvanized welded wire fabric. The wire fabric mesh should be pulled taught and stapled around the perimeter using 1″ or 1 1/4″ galvanized staples.
As an alternative to the bracing shown in Figure 6, you can use a gusset made of exterior grade plywood or galvanized sheet metal, as shown in Figure 7. Using gussets rather than cross bracing will provide more area for storage underneath the greenhouse bench.

The fifth greenhouse bench uses wood slats that are wired together as the base for the bedding flower and or vegetable trays and flats, as shown in Figure 8.

The wood slats, which are wired together, make for a very economical base material. The product is identified as wood lath or snow fence, as shown in Figure 9.

The sixth greenhouse bench is a wood step bench. This bench can be built as a one sided step bench or as a two sided step bench, as shown in Figure 10. This style of greenhouse bench may be advantage for younger children who would have a problem reaching the deck of a standard greenhouse bench.
