Round Cold Frames

Round Cold Frames, also known as hoop houses, have become poplar because of their affordability and versatility. Commercial farmers, hemp and medicinal growers, and residential hobby gardeners can use cold frames to protect outdoor crops from harsh weather, provide shade to plants to prevent scorching, and extend their plants' lives by overwintering. Cold frames can be used with poly film and shade cloth to provide the ideal growing environment to meet your needs.
