Milliken Mushrooms Grain Spawn Bags


  • HIGHEST QUALITY BAGS – Durable and simplistic resulting in perfect spawn bags every time with our professional mushroom spawn bags! Our most user-friendly mushroom bags are super strong, pliable, and super easy to use.
  • IDEAL FOR SPAWN – Built for spawn incubation, these bags provide an ideal environment for mycelium growth in three ways: 0.2-micron gas exchange filter allows for gas exchange with maximum contamination resistance. Integrated injection port self-heals after removing the needle. After autoclave these bags remain pliable; no more holes or tears exposing sterile spawn to outside air or contaminants.
  • CONVIENIENT – The integrated self-healing injection port allows for fast and easy inoculation.
  • STRONG AND FLEXABLE – At 3-Mil’s thick, our bags are among the thickest in the industry, however, unlike cheap Chinese bags, these bags remain flexible even after sterilization. No more bag holes and tears!
  • 0.2 MICRON PREMIUM GAS EXCHANGE FILTER – High quality air exchange filter allows your mycelium to breath during the colonization of the grain spawn.
