Abstract: A self-supporting thermally-protective plant enclosure includes a plurality of elongated hollow closure bodies each having a pair of outer and inner transparent walls. Each outer and inner wall are peripherally interconnected by a base, a top and a pair of opposite sides extending upwardly from the base to the top. Each closure body is closed along the opposite sides and base and is open at least through a portion of the top, defining an internal cavity in the closure body capable of receiving and holding a quantity of fluid therein. The closure bodies are positioned in side-by-side relation and are coupled one closure body to the next along the opposite sides thereof so as to form the plant enclosure with an open top and bottom and an annular configuration surrounding a protective plant growth chamber.
