The Fleece Plant Tunnel is essentially the same product as our lightweight row cover, but with a built in skeleton of metal hoops to go over the row. This garden plant tunnel collects warmth and insulates plants in the row, while allowing sunlight and water to filter through to the vegetables or herbs. The sturdy support hoops are made from galvanized steel, protected against rust. Ends close with an optional drawstring to keep insect pests out. This is a great product for protecting Brassicas from the Small White butterfly (cabbage moth). Once installed, this product measures 310cm long, 50cm wide, 40cm tall (10'2" long, 20" wide, 15" tall).
