What Are High Tunnels?

High tunnels, also known as hoop houses, are relatively simple polyethylene-covered unheated structures that typically do not use fans for ventilation. They can be covered with one or two sheets of plastic; those covered with two have an air layer in between, thus offering better insulation, and consequently, more cold protection.

High Tunnel

Season extension techniques, such as high tunnels, can allow producers to extend the time period over which cash flows are generated from produce crops. High tunnel production of leafy greens and herbs can also enable producers to market products at higher prices, before the start of a traditional local season. High tunnel leafy greens and herbs are typically added by producers already selling through direct market channels; especially farmers markets, CSAs (community supported agriculture), local restaurants, and groceries.

High Tunnel

High tunnels can provide the protective environment necessary for growing greens throughout the winter months. Tunnels do not have a permanent heating system, but instead are passively solar-heated. Nighttime low temperatures within a structure covered with two layers of plastic (with an insulating layer of air in between) generally average about 7º F to 8º F warmer than outside temperatures. Structures covered with just a single layer of plastic often realize only a 3º F increase in nighttime lows. Row covers used in conjunction with the high tunnel will provide further cold and frost protection. Because row covers also block sunlight, they should not be left on for prolonged periods during the winter. Placing the row covers over hoops will help to keep tender leaves from freezing to the fabric. As an alternative, a portable heater can be used when unexpected drops in temperature occur.

High Tunnel

However, due to rising energy costs, the use of heaters should generally be limited to short durations. Often these extra precautions against cold are not necessary as many greens will recover from an overnight freeze and continue to grow with warming temperatures the following day. Opening the sidewalls is imperative for good air circulation and temperature control, even in winter. During sunny days, temperatures in the tunnels can be 30º F to 40º F higher than outside temperatures, necessitating that the tunnels be adequately vented. Lacking the automated ventilation system of more elaborate greenhouses, high tunnels are ventilated by manually rolling up the sidewalls in the morning and closing them at night. Orienting the houses perpendicular to the prevailing wind on the farm will help facilitate air movement

1.Basil – Ocimum basilicum1. Basil. Basil tops the list as the most popular culinary herb. Basil is a very tender plant and should be kept indoors until there is no danger of frost. Growing basil starts in plug trays can work great for basil. Expect to be selling lots of these, so keep the fresh plants coming
