International Greenhouse Company has been building commercial greenhouses around the country and around the world for the past 19 years. During this time period, hundreds of greenhouse projects have been completed in almost every state and several different countries. In 2001, this wealth of knowledge was tapped in order to launch an online web store for greenhouse growers to purchase structures and supplies for their commercial growing operations. In 2003 our rapidly growing web store at igcusa.com was moved to our GreenhouseMegastore.com domain which has since become one of the best known and trusted brands in the online greenhouse community.Over the past several years, Greenhouse Megastore has grown to be a leading supplier of hobby and commercial greenhouse structures, greenhouse and garden supplies, patio covers, metal buildings and much more. We believe the foundation of our success can be attributed to the in-depth level of technical knowledge that only comes from experience in the growing industry.You can shop with confidence from Greenhouse Megastore. In addition to the lowest prices, you get the experience and knowledge of a company that has built and sold commercial greenhouses for over 19 years now.
