How to grow Reishi

Instructions

Place the Capsule in Sproushi (Without opening the bag)
Check it every so often to see if Reishi "antlers" are growing - Or check daily on the app to see if the status changes from "Primordia" to "Pinning".
Once you see antlers, grab a sharp and clean knife
Tip: wash with dishwashing soap
Cut a wide opening through the plastic packaging around the antlers without cutting the antlers
Place the enclosures to close Sproushi
Press Start!

Primordia – The white mycelium spreads through the block, turning it solid and ready for fruiting. This is how your capsule will look like on arrival
Pinning (1–2 weeks) – Tiny knots form on the surface — the first signs of Reishi “baby antlers.”
Option 1: Maturing "Antlers" (4–8 weeks) – Slender, finger-like stems grow upward. They can get quite tall and colorful.
Option 2: Maturing "conks" (, 4–8 weeks) – The antlers widen into flat, varnished shelves called conks. These take patience, but develop the iconic flat Reishi look.
Ready to harvest (~ 8 weeks) – Fully grown antlers or conks harden and develop their deep red-brown, lacquered surface.

Harvest when the antlers or conks have fully developed their deep red-brown, varnished surface. They should feel firm and woody.
Use a clean knife or garden shears to cut the whole antler or conk at its base, close to the block.
Reishi is tough but can crack if forced. Cut cleanly instead of pulling.

After the first harvest, Gently remove leftover stem bases or debris from the block’s surface.
Reishi is slow-growing. New pins may take over 2 weeks to appear, with the second flush developing more gradually than the first.

Once your capsule has stopped producing mushrooms, remove it from the bag.
Break it up into smaller chunks to help it blend with the soil.
Bury the pieces a few centimeters deep in a shady, moist spot in your garden or compost.
Keep the area lightly watered, the mycelium will enrich your soil and may even surprise you with a few more mushrooms outdoors.
