A plant growing medium is enclosed by the envelope. The first and second walls each has a plurality of micro-holes, and a network of interconnected ribs that are indented from an outer surface of the first or second wall to define a plurality of flow guide channels. The second wall further has openings to receive plants. The first wall further has drain holes. The envelope has high air permeability due to the micro-holes while still possessing a relative high strength due to the network of ribs.
