Dewitt Plant Seed Guard is a lightweight, .5 oz., white spunbond fabric for use in commercial, residential, and greenhouse sites. It creates an excellent micro-environment for seed germination and seedling growth and acts as a barrier between fungus spores and insects. This fabric provides a 90-95% average seed germination compared to 60-65% with straw or hay. This frost cloth can be used as a row cover to provide low cost insulation against the elements.
