Instructions for our interior mushroom grow kit - Oysters and Lion's mane

This Grow Kit is designed to give you a scientific experience, tasty mushrooms, and fun. It is made up of a living mycelium block, substrate, and water. In the right conditions, the first harvest is guaranteed.


Before starting, open the box to make sure that the substrate is entirely colonized, meaning the white mycelium has reached the bottom

of the bag. Until the mycelium has entirely colonized the substrate, keep the bag closed and the Grow Kit at room temperature. Once

colonized, for later use, store the Grow Kit in the refrigerator for up to four weeks. *

1. Fruiting

Remove the block from its box. To concentrate the fruiting in a single point, remove excess air from the upper part of the bag by folding it over the block and taping closed. If small mushrooms are already forming, make an incision at that place. If not, put the block back in its box and carefully cut a 5 cm slit in the plastic in the middle of the box’s window.

2.   Hydration

Spray your Grow Kit and mushrooms every day. Insufficient humidity can be noticed if the caps become yellow, dry out, or stop growing. If this happens, remove the grow kit from the box and immerse it in cold water for one to six hours.

Drain excess water through the hole.

3.   Harvest

After 4-8 days, when caps are fully developed, harvest all mushrooms. If spores are being released, leaving a light white powder underneath the caps, harvest immediately.

4.   Start Again

To initiate another harvest, place Grow Kit in the refrigerator. * After 5-10 days, immerse in cold water for 1-6 hours and remove excess water through the hole. Close the first opening with tape and make another slit on the other side of the bag or where primordia are forming. Repeat steps 2-3.

* Except for the pink oyster which is a tropical mushroom and must always be kept at room temperature. It’s mycelium is pink.
