"Use of low tunnels to improve plant growth in high tunnels"
If you put these low tunnels inside a greenhouse or high tunnel (unheated greenhouse) plants are even more insulated from the outside cold. Our first trials using this arrangement will be looking at the temperature ranges using different materials as covers for the low tunnels. Permeable fabrics, plastic sheeting and permeable plastic all have their benefits and drawbacks.
