Abstract: The inflatable greenhouse is an approximately hemispherical dome-shaped inflatable structure which is entirely self-supporting when inflated. The greenhouse has a double-walled structure of plastic sheet material which gives the greenhouse structural rigidity when inflated and which increases the thermal protection provided by the greenhouse. The walls of the greenhouse are made of a transparent or translucent plastic material to allow optimal light transmission for photosynthetic plants or of a light filtering or opaque plastic material for light-sensitive plants and animals. The greenhouse has an access door through the wall to allow easy access to the interior of the structure. The door is placed such that it does not interrupt the structural integrity of the inflated dome-shaped structure, therefore no rigid structural members are needed to support the walls.
