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.
By Johanna Silver, Sunset's test garden coordinator. I've wanted to grow potatoes in a tower for some time now. It saves space by getting the crop to grow up rather than sprawling out in the ground. Here's how it works: The plant grows and its stem lengthens, as do the underground stolons from which the tubers grow. Give the stem more height to grow and it will, increasing the space for stolons and thus tubers. Click ahead to see our project unfold â and how you can make these simple potato towers, too.
