How many business have greenhouse supplies?

Many businesses sell greenhouse supplies of some sort, but determining which supplier you should use will be largely dependent upon the scope of your greenhouse project. For instance, you may find many standard green house supplies such as fertilizer, watering systems and the like, at your local home improvement center or nursery. However, if you are looking for supplies for commercial application, you may have to visit farm/agriculture supply stores, or specialized vendors who specialize in large-scale greenhouse operations. It is important to know that many areas have statutes in place that govern who can purchase particular agricultural chemicals, and in what quantities.
