What is a high tunnel?

-A high tunnel, or a polytunnel, is made of polyethylene. Our high tunnels consist of 2 layers of polyethylene. One end is plywood and the other is polycarbonate.  High tunnels are mainly used in temperate regions for season extension in similar ways as greenhouses. They can be used to provide a higher temperature and/or humidity than available in the region. High tunnels also protect crops from extreme weather in a semi-controlled environment.


Isn’t a high tunnel the same thing as a greenhouse?

-No, a high tunnel is considered a temporary structure, whereas a greenhouse is considered a permanent structure (made with concrete). A high tunnel is not considered a building and therefore does not need to follow strict building codes.

What are some benefits and consequences of high tunnels?

-High tunnels are extremely beneficial in season extension (especially if they are heated). They are also great for climate and moisture control. Since there is no rain on the crops, many diseases caused by excess moisture are prevented.

High tunnels can be a bit on the expensive side, but are definitely a great investment. One specific problem Farm to YoU NH has noticed is the build up of salt (salinization) on the top of the soil. This is most likely due to the constant use of drip irrigation and lack of rain to leach the soil.

What crops do you produce?

-Head Lettuce, Greens Mix, Spinach, Kale, Tomatoes, Squash, Peppers, Onions, Garlic, Pak Choi, Swiss Chard, Carrots, Celery, Jalepenos, Cucumbers, Strawberries, Asparagus, Okra, Edible and Non-Edible Flowers, Herbs, and much more!
