Low tunnels have already shown their effectiveness this season. Mark Hollen, a participating producer has set-up over 100 feet of low tunnel over his garden plots and is using them to assist with carrots, turnips and beet production. Mark lives in a frost pocket, and experiences heavy frosts early. He has already had several hard frosts on his farm this season.
Last week he placed plastic covering on top of his pepper plants to keep them from feeling the effects of the frost that was expected that night. The low tunnel covering completely saved those plants that were placed under the covering.
As you can see in the picture, only half of the plants were covered. The uncovered plants were killed off, and the covered ones were saved. This is a great example of the effectiveness of low tunnels. Even just a simple plastic covering (bottom left of picture) was able to save his pepper plants.
