GrowAway Row Covers are a great solution for those wanting to get a jump-start on the garden season! The reusable covers have slits on top that allow for water and air exchange while not leetting animals or wind inside. It's like having a mini-greenhouse that'll protect seeds and young plants from animals, pests, frosts and wind. With the reusable covers, seedlings can be transplanted sooner in the growing season. Made of durable, food-safe plastic, the row covers have openings on top that allows for air and water exchange. 26 in. L x 7 in. W x 4 in. H
