Growers Supply has been providing the growing and agricultural industry with high-quality products and consultation for nearly four decades.  As a greenhouse megastore, the company created GrowSpan to supply growers of all experience levels with the finest greenhouses and growing structures, and no matter the size of the operation or the crops being grown, there is an ideal GrowSpan greenhouse that can support and promote improved business.

When purchasing a GrowSpan greenhouse or growing structure, customers will work with a Greenhouse Specialist from beginning to end. Greenhouse Specialists have years of experience working in and with the growing industry, so they can make suggestions and are an invaluable resource for growers and businesses that operate on any scale. They can help every step of the way, and since GrowSpan is a Growers Supply brand, everything is done in-house, ensuring complete control over the project. Customers buying a GrowSpan greenhouse can rest assured that is designed, engineered and manufactured by Grower Supply’s experienced staff, and customers can also take advantage of Growers Supply’s flexible, in-house financing. In-house financing eliminates the needs for a third party, drastically simplifying the process of obtaining the proper financing. Those that qualify can receive terms up to seven years with zero money down and zero interest.

When purchasing a GrowSpan greenhouse, customers will also have access to the wide array of products found in the Growers Supply catalog. With over 30,000 products dedicated to the growing industry, customers will be able to outfit their greenhouse and operation with all the accessories, tools and horticultural products that they need.
