International Greenhouse Company (IGC) is now known as Greenhouse Megastore

Originally known as International Greenhouse Company, Greenhouse Megastore has been building commercial greenhouses around the country and around the world for the past 22 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.
