  15. High Tunnel Costs chassis+ repair/replace+ climate control+ labor

  16. High Tunnel Costs + climate control • ventilation • raised beds, row covers• sensors• heating (temporary, permanent)

  17. Major HT Materials Costs • frame (material, durability, portability, number braces)• film (number layers, type)• end-, side-wall design• climate control

  18. High Tunnel Costs • depend strongly on size, design, features … in OH,new materials cost $2.38-7.24 (avg. $3.95/ft2)

  19. High Tunnel Costs • cannot be insured• usually not taxed (depends on local ordinances)
