On June 20, 2016, we experienced a wind storm with wind speeds upward of 50 MPH. While the plastic cover from our low tunnel system blew off the top of the hoops, the entire system was not damaged. Thankfully, the bungee cords held the plastic close to the side of the hoops, as you can see in the picture below.
There was no damage to any of the low tunnel system or to the plants.
Despite this slight altercation, it was fairly simple to fix by sliding the plastic cover back onto the hoops. All we had to do at that point was to readjust the bungee cords.
