The present invention provides a portable greenhouse structure comprising a base in the shape of a right-polygonal cylinder having a top and a bottom, wherein the base comprises a plurality of wall panels connected along abutting edges; a hemispherical roof attached to the top of the base, wherein the hemispherical roof has a polygonal hole in the apex thereof; and a polygonal panel having the same shape as the polygonal hole, wherein the polygonal panel is moveable between an open position and a closed position, and wherein the polygonal panel sealably covers the polygonal hole when in the closed position. The present invention also provides an apparatus for joining a first panel to a second panel along abutting edges thereof, the apparatus comprising a first extrusion attached to the abutting edge of the first panel, wherein the first extrusion comprises a stem which projects away from a plane of the panel and has a panel side and a mating side; a second extrusion attached to the abutting edge of the second panel, wherein the second extrusion comprises a stem which projects away from a plane of the panel and has a panel side and a mating side; and a clamp which holds the stem of the first extrusion and the stem of the second extrusion together such that the mating side of the first extrusion is in contact with the mating side of the second extrusion.
