extra insulation

when faced with weather extreme, extra insulation for your low tunnels may be needed temporarily. In my garden, for example, I tend to use sheets with a 3-mil thickness for the very end of spring while I prefer 6 mil for extra-early gardening or gardening into winter.

To temporarily increase insulation, I add more layers of sheeting as needed and remove them once the harsh weather passes by. Some years, I’ve even added bed sheets when I ran out of plastic. Again, creativity goes a long way with low tunnels, so use what you have in an emergency.
