      Your Greenhouse Partner

      Anyone can "just" sell you a greenhouse. But we want to do more than sell you a greenhouse structure at a great price. We can help you choose the best type of greenhouse that will work in your location and for your needs. Furthermore, we can design and equip a custom greenhouse building project or assist in applying for any grants that might be available.

      Support from Greenhouse Megastore doesn't end after the sale, either. We always conduct a completely professional and successful construction process and will provide training or growing assistance that's sure to help you use your greenhouse to its full potential. It's part of our mission to help anyone and everyone experience the benefits of horticulture in an achievable way.

      DIY and Commercial Greenhouses

      Find every type of greenhouse for every type of grower. Whether you need impact-resistant polycarbonate greenhouse kits for areas with extreme weather, temporary portable greenhouses that you can set up seasonally, or large-scale cultivation facilities for light deprivation and warehouse growing, we either have a structure ready to ship or can design one.
