This floating row cover traps heat and moisture to produce bigger and earlier crop yields. It protects against frost, insects, and birds. This cover is easy to use - "floats" over crops without support and is reusable. It can also be used as a seed germination blanket (previously called Grass-Fast). Up to 100% improved seed germination (versus straw). Protective seedling cover traps heat and moisture to speed and increase seed germination. Ideal for slopes and difficult areas. Easier to use and more effective than straw.
