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.
There are situations, however, in which your garden might be both high in potassium and high on the pH scale -- for example, if you add potash-rich wood ashes to your garden to raise pH. A soil test kit can tell you if you have alkaline and/or high-potash conditions.t high levels, potash can block the uptake of foliage-boosting nitrogen. For that reason, plants that are grown for their flowering or fruiting potential rather than foliage most benefit from high-potassium soils.
