Abstract

An improved bag for the cultivation of mushroom spawn is provided the bag has continuous gas permeable sealing strips sealed to the inside walls of the bags which covering openings in the bag, so as to allow the bag to be vented without loss of moisture. The openings and sealing strips are positioned close to the top and bottom of the bag so as to maximize air flow through the mushroom spawn without creating dry spots, thereby improving spawn yield.
