Supplies You'll Need

We specifically designed this bag to make it as easy as possible to grow mushrooms with the least number of supplies.

If you do not have a fully colonized block, be sure to start the instructions at the beginning


Materials Needed:

  • Fully colonized mushroom block - Click HERE if your block is not fully colonized.
  • Alcohol Wipes and/or Spray Bottle Filled with 70% Isopropyl Alcohol
  • Clean, sharp scissors or sharp knife
  • Spray bottle
  • Latex Gloves and Face Mask
  • Temperature and humidity control (if possible)
Step 1: Prepare Your Workspace

Ensure a clean workspace. Wash hands and sterilize tools.

Step 2: Cut and Open the Bag

Using clean scissors, cut the top ½” off the bag to introduce fresh oxygen. NOTE: Some harvests may not require this step until mushrooms are ready to harvest.

Step 3: Fold Over Your Bag

Using paper clips, keep the bag folded over along the top so that particulates are unlikely to enter the bag.

Step 4: Choose the Right Environment

Place the grow bag in a clean space near indirect sunlight.

If your bag is looking dry, optimal fruiting requires high humidity. Mist the inside walls of the bag lightly with distilled water once every one or two days. Optional: Use a tent with a humidifier.

Keep the temperature at 75-80°F (24-27°C). Utilize a warm room or a space heater to maintain this temperature.

Step 5: Monitor and Adjust

Regularly check humidity and temperature. Adjust to maintain optimal temperatures. Keep the surface moist but not overly wet.

Step 6: Watch for Primordia Formation

Within a few days, primordia (early mushroom structures) should emerge on the block.

Step 7: Increase Light Exposure

As primordia form, gradually increase exposure to indirect light, signaling mushroom growth.

Step 8: Harvesting

Harvest mushrooms when they reach the desired size. Cut at the base with clean scissors or a knife for the best texture and flavor.

Remember, mushroom cultivation is an art; adjust based on your environment. Be patient and observe growth patterns for necessary adjustments.
