I built this 16'L x 4'H x 2.5'W trellis/cage to protect our veggies from the dry heat and dryings here in the high desert in New Mexico. There is an internal horizontal shelf for climbing veggies like beans and cucumbers to climb protected from he heat and in the winter the light weight row cover cloth will be replaced by 6 mil plastic to extend the growing season. There will be three openings to access the veggies.
