NOTE: This size of building is not freestanding and must be secured to a wall or similar for stability. The Maxim is ideal if your growing space is limited. One of the key differences compared to the Compact is the additional 7” of roof height, which can allow for a third shelf to be fitted and, together with taller doors, the result is a larger growing space. As standard are the double doors and low threshold along with cantilever bracing for extra strength, a superb upgrade especially if the building is sited in a location more exposed to the elements. Package deals are available for this model making it one of the best performing greenhouses in the market place at this size. NOTE: FOR PACKAGE DEALS PLEASE DOWNLOAD PDF.
