what to grow in a high tunnel
What is the typical size for a commercial high tunnel? High tunnels used for growing horticulture crops commercially are typically 20-30 ft wide and 100-200 ft in length with a height of 9-17 ft in center.ince high tunnels are a relatively small planting area, compost is also economical for use in the high tunnel. ALWAYS have your compost source tested for nutrients, pH and soluble salts. If you are purchasing compost from a local farm, determine if any phenoxy herbicides had been applied to the meadows or pastures.
