This is the greenhouse that creates a backyard paradise for monarch butterflies. It acts as a nursery by creating an ideal environment for laying eggs and functions as a sanctuary with walls that keep out predators such as robins and cardinals. The unit has a raised garden bed and comes with a mat of seeds for growing nectar plants and milkweed—an essential food for monarch larvae that is decreasing in population. It has a transparent PVC roof that lets in sunlight while blocking UV rays and nylon walls that have polyester netting and round openings to allow butterflies in and out. Can be installed on a lawn or on hard surfaces such as rooftops, patios, or decks. Made from recycled plastic and sustainable hardwood fibers. Assembly required. 4' L x 4' W x 6' H.
