Considerations with high tunnels/greenhouses prior to a hurricane

  • Check the area around the structures for loose objects. Look for objects that could be blown at the structure and cause damage to the glazing and remove them.

  • Inspect for dry or weak tree limbs that could fall on the greenhouse.

  • In general, you should close all vents to minimize the ability of the wind to lift the structure.

  • Consider removing the plastic if anticipated wind speed will reach greater that 80mph (this threshold could be higher or lower depending on the rating of the specific structure).

  • On air inflated greenhouses, increase the inflation level between the two layers of plastic covering.  Also, tape and repair any tears/rips in the covering.

  • If the structure is equipped with a heater, secure the exhaust pipe as it can move easily in high wind.

  • Remember to vent the structure after the storm has passed if crops are inside.
