Our 100% mycelium grow kits are very easy to set up when you follow these instructions. These grow kits produce their first harvest fairly quickly. The first buds are already visible after just one week. Low and high temperatures may slightly delay this growth process. It usually takes one to two weeks before the mushrooms are fully developed.

Always work as sterile as possible! Don’t breathe onto the grow kit or into the bag. Wash your hands or wear sterile gloves.

Step 1

Take the grow kit, plastic bag and paperclip out of the box. Remove the lid of the grow kit and rinse the lid under running water. You will need it again later. You should see what looks like white mold, this is the mycelium that will grow mushrooms.

Place the grow kit in the plastic bag without the lid (opening at the top). Wrap the bag around the kit and leave it for a week, or until mushrooms begin developing.

Step 2

Place the grow kit in an area with a temperature between 18 °C and 28 °C. NEVER place the grow kit in direct sunlight. Mushrooms do not need light to grow, but it does influence their maturation and orientation. Although mushrooms will grow at almost any temperature above 15 °C, 23 °C is the ideal temperature for an optimal harvest.

Special heat mats are available to ensure this temperature and not have to heat the entire room. If you’re using a heat mat, place the kit on it with a towel or glass in between. Monitor the temperature carefully! You don’t want to overheat the kit.

Step 3

Starting after one week, use a plant sprayer with clean water to spray the inside of the bag to keep it at the same level of humidity it started with. If after a while more mycelium develops but no mushrooms, then it might be a sign it’s too humid.

DO NOT spray directly on the kit itself!

Step 4

Close the bag with the paperclip after each spraying. The bag has built-in filters so you do not have to worry about air circulation.

Step 5

The first mushrooms will be visible after approximately one week. You can begin to water the bag less often, but don’t let it dry out. Your first harvest will be about a week later.

Make sure that you harvest before the first spores begin to fall! The spores won’t affect the strength of the mushrooms, but they with change the color and possibly the taste.

Step 6

These grow kits produce several mushroom harvests.

To do so, fill the kit with clean tap water after the first harvest. This process is known as cold shock. It breathes new life into the mycelium and ensures that enough moisture is present for the mushrooms to grow.

Step 7

Place the lid of the grow kit back on the kit. Let the kit rest for 12 hours. Open a corner of the lid and drain the excess water. From here you can follow the instructions from step 1 again. This process can be repeated several times for multiple flushes.

Troubleshooting

When you see the majority of mushrooms pop up on the bottom and/or sides or when no mushrooms are visible after 10 days: Take out the cake and put it on its side.

When you detect mold on your grow kit: cut out the mold with a knife and continue growing. Beware that you work as sterile as possible!
