ABSTRACT:
The present invention relates to a retractable greenhouse which is constructed from at lease two left-right horizontal members which are supported at each opposite distal end by a left-right vertical support post and at least two front-rear horizontal members which are supported at each opposite distal end by a front-rear vertical support post. Each front-rear system includes a front-rear cover sheet which may be raised or lowered by a motor. Each left-right system includes a left-right cover sheet which is raised to a left-right horizontal member, travels to another left-right horizontal member (to form a top), then lowers to the ground. This forms a retractable greenhouse.
