Lion's Mane Mushroom Grow Block Kit Instructions

Lion's Mane Mushroom Grow Block Kit


Lions Mane mushroom grow block

Congratulations, you are now the owner of a lion's mane mushroom grow block. The “block” is composed mainly of hardwood sawdust and wood chips bound together with mushroom tissue or “mycelium” contained in a plastic bag. Mycelium is the white fluffy material covering the outside of the block. The white mycelium is very delicate and you should avoid touching it as much as possible. When moving the block, hold onto the top and bottom to minimize damage.

If you wish to delay the fruiting for a few days, place the block in the refrigerator without opening the bag.




  1. Remove the mushroom block bag and humidity tent from the box.

  2. Expose the block to fresh air by cutting a 1-inch "X" into the plastic bag on one side of the block.  Handle the block lightly as to not disturb the mycelium.

  3. Fold the excess upper portion of the bag under or around the block.  With the box on its side, place the block back into the box with the cut side exposed at the open end of the box.  Place the box in the humidity tent with the cut "X" facing towards the opening of the tent.  Close the tent using the included binder clip.  Closing the tent prevents drying that would stunt mushroom growth.

  4. Place the kit in indirect light.  At least 12 hours of very low light is necessary for growth.  Mushrooms will grow between 60-80 degress F.

  5. Mist the surface of the block and the inside of the humidity tent 2-3 times daily with non-chlorinated water.  Avoid soaking mushrooms themselves as they may become soggy and mold.  Close the tent after misting.

  6. The lion's mane block will start mushroom formation about a week after initiation. Normal room temperature is great, 65-75F. They will first appear as small bumps and then quickly mature into fully formed toothed mushrooms. Harvest your mushrooms when the top of the mushroom near slit in the bag begin to turn brown/tan. Remove all mushrooms large and small by pulling them off at their base when the majority reaches maturity. After harvesting, your block will go dormant for about a week. Continue to mist during this period of rest. Repeat the cycle until no more mushrooms appear. Your block should produce 3 to 5 cycles of mushroom crops before becoming exhausted. Near the final crop the block will be surprisingly smaller than its original size.                                                                                                                                                                                                                                                                                                                      

    Pick mushrooms as they mature, but before the cap edges curl upwards.  After all mushrooms have grown and been harvested, the block will go dormant for 2 weeks.  During this time, continue to mist daily.  The kit will produce 2-4 flushes. 




    If you don't mist daily, your block will die.


    If your mushrooms are too small, put a small fan in the room to give them more air to grow!  But do NOT aim directly at the mushrooms or they will dry out.


    Adding a humidifier in the dry seasons of the year is recommended.
