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.
