In general our greenhouses are designed for do-it-yourself installation. They can usually be constructed in 2 to 4 hours with simple hand tools. The exception is the Spring Gardener Gable Greenhouses that use wingnut fasteners and can be assembled with no tools.
The Weatherguard and Spring Gardener Greenhouses are designed with a non-rigid flex frame system, allowing them to move in moderately windy conditions. Locating the greenhyouse next to a natural or man-made wind block (e.g., building, fence, trees, hedges, etc.) will help prevent the greenhouse from potential damage in severe wind conditions. Using the optional anchoring systems will also help insure that the greenhouse will be stable under diverse weather conditions.
Make sure that the location you have selected for your greenhouse is a FLAT, LEVEL, RECTANGULAR site free of all debris.
The Clearspan Greenhouses run from the very simple construction as in those above to more complex as the sizes get very large.
