The National Greenhouse Manufacturers Association
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.
NGMA members are committed to building greenhouses with a level of professionalism you won't find elsewhere. What's more, you'll find that the NGMA structural members are more than just greenhouse builders, they are the leading edge of the very latest technology. So if you're looking for the best greenhouse or component manufacturers North America has to offer, contact NGMA. Be a part of the most extensive list of engineers, dealing with horticulture, agriculture, building, structural, growing and design issues the industry has to offer!
