Speckled Chestnut Mushroom Kit Instructions
Philota adiposa have beautiful speckled orange caps that stand out in the template forests they call home. They have long history of culinary use in Japan, but have only recently started being grown in western countries. They take a bit longer to grow than other species, meaning you'll get more time to admire this stunning mushroom as it grows.
Each species of mushroom is a different growing experience. Even if you have grown mushrooms before, please read the instructions for your kit carefully before proceeding. If you run into any problems please see our FAQ.
Step 1: Mycelium Check
Inside this box mycelium has has been happily breaking down the organic growing medium and converting it into energy. At first the mycelium is white, but as it gets ready to produce mushrooms it takes on a orange tinge.
Remove your block from the box and examine its colour.
Mycelium is white = needs more time in a warm dark location (under 25 degrees)
Mycelium has an orange tinge = Ready to fruit
If your block is completely white, return it to the box and move your kit to a warm location - over 15°C and NO MORE THAN 25°C. Check it once a week until it has developed an orange tinge.
If your mycelium has an orange tinge you can now move on to step 2. If you do not want to move on to step 2 at this time, you can keep your kit in the fridge or a cool place for up to two weeks.
Step 2: Finding an Ideal Location
Speckled Chestnuts grow best between 13-25°C, are not in direct sunlight and have plenty of humidity and some fresh air. Finding or creating the perfect environment is key to getting the most mushrooms out of your kit.
-
Find a humid spot with indirect sunlight or ambient light to place your box. Near the kitchen sink or in the bathroom is often a good choice. Do not enclose in a box or cupboard as it needs access to fresh air.
-
If you've purchased a thermometer/hygrometer, a humidity reading over 50% and a temperature reading between 10°C and 20°C is ideal.
Step 3: Initiating Fruiting
In nature the mushroom fruiting process of is triggered by a range of changes in the environment. Fresh air and ambient light become available as the mycelium breaks through the ground layer or the extremities of a log. Seasonal changes bring wetter weather and humidity increases. You will now imitate these changes in the following way:
-
Using a clean knife, puncture the exposed bag in a cross pattern each slit at round 7cm. This will initiate the fruiting process and your mushrooms will grow from these slits
-
Mist your kit according to the misting instructions below.

Step 4: Misting
Mushrooms prefer to grow in an environment with 80-90% humidity. Because of this, you'll need to gently mist your kit regularly with a clean spray bottle. You want to create a humid environment for the mushrooms and to keep their bodies moist, rather than to 'water' them as you would a plant.
-
Before your mushrooms begin to grow, a gentle mist 4-6 inches from the hole the 3 times a week will suffice. You do not need to mist the box so much or so close that it becomes sodden.
-
If you are using a large, household spray bottle, be sure it is set to 'mist' instead of 'stream' and mist from 6-8 inches from the box.
-
Once you see your mushrooms begin to pin, mist them twice a day and make sure to keep the mushrooms moist as they won't be able to grow if they begin to dry out.
Step 5: Pinning
'Pinning' should begin within 5 weeks of initiating fruiting. If you haven't seen any pinning after 5 weeks please see our FAQ. Once they have begun to pin, your mushrooms will grow rapidly. Keep the mushrooms moist during this period.
Step 6: When to Harvest
Harvest your mushrooms when the caps have begun to flatten but before the edges have flipped up. Generally from first pinning it will be 10-15 days before harvest - a relatively long period of time compared to other species like oysters. A brown dust under your mushrooms means they have started to drop spores. Your mushrooms will be at their most tender if you harvest them before they sporate, but they'll still be perfectly delicious if you don't quite catch them in time. Just don't forget to wipe off your counter!

Step 7: Harvest
-
To harvest, twist and pull the entire bunch off at the base. Do not harvest one mushroom at a time, as this will slow your mushrooms' growth.
-
Be sure that you have removed all of the mushrooms' base from the hole. You should be able to see brown growing medium to ensure the next flush.
-
Cut off anygrowing medium that has stuck to your mushrooms. You can store your mushrooms in the fridge for up to a week.
Step 8: Initiating The Next Flush
Did you know that your box has the ability to produce several clusters or 'flushes' of mushrooms over time?
Place your kit in the fridge for 12-24 hours. The change in temperature tricks the mycelium into thinking that the seasons are changing and will encourage them to flush.
You can then return your kit to your chosen location and repeat steps 4-7. Times between flushes can vary from 5-10 weeks, so be patient and don't forget to keep the humidity up by misting. Your kit may flush several times, but the amount of mushrooms will reduce with each flush and the time between flushes will increase.
For more detailed tips on encouraging more flushes out of your kit, please check our FAQ page here.
Step 9: What to do with your kit when it stops producing mushrooms
Did you know that fungi play a key role in storing carbon? Trees and plants remove carbon from the atmosphere and fungi break down plant waste to create new carbon-rich soil. Clean air, healthy soil and delicious mushrooms: just one of the many ways fungi are incredible!
Once your box has finished flushing, open the box and remove the mycelium block from its plastic bag. Discard the bag in the general waste. You can now recycle the box and additional packaging and compost the block. Alternately plant it in the garden to see if it will gain a some energy and produce one last seasonal crop for you! Simply dig a hole in a shady spot, bury the block and cover it over with around 5cm of soil. Water it occasionally to keep the soil moist.
