Metrolina Greenhouses is a family-owned, wholesale plant and se​rv​ices company that started business in April 1972. We are the largest single-site heated greenhouse in the United States at 162 acres under roof. In addition to greenhouse space, we have approximately 15 acres of outdoor growing space and are still expanding at our Huntersville facility. Our York, SC facility has an additional 175 acres of outdoor growing space. Metrolina Greenhouses is one of the most automated greenhouses in the United States and has many internally designed machines from automatic plant transplanters to mechanical shipping belts. We ship to Big Box Retailers, Mass Merchandisers, Home Improvement Chains and other greenhouses along the East Coast. Our products typically stay within a 500 mile radius of the greenhouse, so that puts us in most states on the East Coast. During our peak season (March-June) we ship over 180 trailer loads of product a day! Other Noted Facts: We use up to 1,500,000 gallons of water every day. For every 1 inch of rain that falls on the greenhouse, our roof and pond system allow us to collect and store 3 million gallons of water in 25 acres of retention ponds. This allows us to use recycled/recaptured water on all of our crops. All the air in the greenhouse is exchanged every minute during the summer months for cooling due to our unique open-roof greenhouse design. 75% of the greenhouse is cooled using passive “MX” style ventilation (our famous open roof system)! We use 12 tractor trailer loads of sustainably harvested Canadian Sphagnum peat moss each week (because our plants are grown in a sphagnum peat moss based mix). We heat the greenhouse during the cooler months with biomass fuel via our wood-driven boilers. We produce over 2 billion BTU’s of heat while being environmentally friendly. We produce 110,000,000 Seedling and Cutting plugs which in turn produce: 7,000,000 Hardy Mums 6,000,000 Summer Annuals 5,000,000 Hanging Baskets 3,000,000 Poinsettias 1,800,000 Bedding Plant Flats 11,000,000 Perennials​​
