Harvest Guard creates a semi-greenhouse environment, raising the air temperature approximately 10-15 degrees underneath it. Protecting against frost, snow, and ice. Made with durable weatherproof materials, it's designed to withstand the elements. Once the season is over, you can roll and store it away, and you can even wash it with mild soap and dry it on a clothesline. Simply stretch it over the desired area and secure the adjustable closure strap for custom protection. No expensive professional tools are required.
