The heavier weight grade Agribon AG-50 26' x 500' row cover is excellent for frost, wind, over wintering, insect and animal protection. The 1.5 oz./sq.yd. cover allows 50% light transmission and offers 6°F of frost protection. This row cover can be used as a floating cover, but if the crops are still growing then we suggest using support hoops to avoid damage to growth points. Polypropylene fabric is spun-bonded with UV stabilizers and is durable enough to get more than one season out of it. Row cover comes folded in half, then rolled for ease of handling and shipping.
