Structures and Kits
Whether you’re looking to build a small metal greenhouse, a traditional wood structure or a garden-based low tunnel, It starts with a foundation. One you can trust, feel secure with and ultimately not even think twice about, letting you truly focus on what matters and get back to growing.
At Greenhouse Megastore, we pride ourselves on being that foundation. We do more than just provide a greenhouse frame kit and cover before saying, "Good luck." The greenhouse and gardening experts on our staff work with you hand-in-hand by providing greenhouse drawings, plans, training and — most importantly — a level of service and knowledge that assures you're getting a best-in-class experience.

The right growing structure will help food crops and ornamental plants thrive by shielding them from harsh weather. Greenhouse Megastore has a huge selection of plant structures to fit your available space, budget and growing needs.
DIY and Engineered Greenhouse Structures
Our inventory includes permanent and temporary greenhouses from the world's leading manufacturers. Greenhouse kits come in classic and modern designs to add style to your landscape as they provide quality grow space. Low tunnels are perfect for protecting a specific crop in a garden bed, while high tunnels and hoop houses allow more comprehensive planting. If you are a professional gardener, look at commercial greenhouses and retail greenhouses that are designed from the ground up for maximum efficiency.
Plant structures aren't just for cooler weather, either. Our shade structures provide shelter against excess sun and heat that can stifle certain crops. For advanced growing, an insulated greenhouse gives you full control over the interior climate, letting you plant everything from root vegetables to tropicals at any time of year.
