WHAT ARE HIGH TUNNELS?
🏡💨High tunnels, also referred to as hoop houses, are low-cost, usually unheated, metal-tube structures 6° higher than outside, and if low tunnels are used over the growing beds inside a high tunnel,
9° can be gained.
🏡💨 High tunnels can add at least four weeks to the beginning and end of the normal growing season, giving the urban
grower a hand up in expanding and extending markets, growing more variety, and adding resilience to the farm.
🏡💨 High tunnels extend the growing season by protecting crops from harsh weather, pests, and diseases. However, they create unique conditions that can cause soil, pest, and disease problems, requiring careful management for healthy crops and good yields.
