Base Kits & Extensions

The advantage of a base is to give an increased resistance, stability, and securing your greenhouse to the ground especially throughout severe weather conditions. It must be precisely installed to the bottom. The base will support your greenhouse for many years to come by making it fixed and stable. You might also be considering bountiful harvests and possibly expanding your greenhouse. Some greenhouses are expandable. You may be encouraged to purchase extension kits which give you additional growing space. Just leave a room for future extensions.
