An improved bag 20 for the cultivation of mushroom spawn has front and back walls 22, 24 having a plurality of openings 26 disposed therethrough, a top 28 and a bottom 30, and left and right sides 32, 34. A plurality of gas permeable sealing strips 36, 38 are sealed to the walls 22, 24 and cover each of the openings 26. The openings 26 are arrayed in a pair of parallel rows 42, 44 proximate respectively the top 28 and the bottom 30 of the bag 20 so as to provide more uniform breathability of the mushroom spawn through the gas permeable sealing strips 36, 38, the openings 26 and the gas permeable sealing strips 36, 38 being constructed and arranged so as to reduce dry spots in the mushroom spawn and improve spawn yield. <IMAGE> |
