A 49 ft hose is built into this greenhouse, running the length of the tunnel so beds are watered without dragging a can through a 15 ft aisle. Floor area comes to 15 x 7 ft at 7 ft high, which holds several raised beds with room to walk between them, and eight mesh windows plus a 42 x 69 in roll-up zipper door move air on hot days to stop humidity building. The frame is galvanized steel under a PE cover, together weighing 52.5 lbs - the heaviest and most permanent structure in this range. Assembly is required and best done with two people.
