Mycelium discs
Follow these instructions to grow your own mycelium network from our mycelium discs
1
Step 1
Activate!
Soak the mycelium disc in cold water for 24 hours to activate it.

Step 2
Place on cardboard
Place the disc on a sheet of damp cardboard and watch the mycelium start to grow. Keep it in a dark place and keep it hydrated by misting with water.

Step 3
Feed your mycelium
Once hydrated, the mycelium is alive and hungry. Feed it cardboard, woodchips, twigs, straw, or kitchen waste like coffee grounds. Treat it like a pet that needs food, water and air!

Step 4
Watch for mushrooms
After a few weeks of feeding, baby oyster mushrooms will start to appear. Keep them somewhere with indirect light and mist regularly with a spray bottle.

Step 5
Harvest your mushrooms
If kept well hydrated, mushrooms will double in size daily. Harvest just before spore drop, when the edges of the cap start to lift.
