The National Greenhouse Manufacturers Association (NGMA) is a professional trade organization for the manufacturers and suppliers of greenhouses and greenhouse components. It's one thing to manufacture a greenhouse. It's quite another to actually build it to codes specially for a grower's needs. But it is for just that reason, the National Greenhouse Manufacturers Association membership brings together some of the most experienced and knowledgeable manufacturers in the industry.
