LION’S MANE GROW KIT INSTRUCTIONS

Our mushroom grow kits make it incredibly easy, fun and satisfying to grow your own gourmet mushrooms at home. Follow our 6 step process and harvest your first high yielding cluster of Lion’s Mane mushrooms in as little as 3 weeks!

Step 1 - Location

In order to get the best out of your mushroom kit, you will need to re-create the optimum conditions for mushrooms to grow. Mushrooms thrive at room temperature (10-23°C) with high humidity as well as sufficient light and air flow. Luckily, this is pretty easy to achieve!

We recommend placing your grow kit on a kitchen counter, table or window sill.

Be sure that the grow area is not exposed to direct sun light or is placed above a radiator as this will dry the grow kit out. If placing on a window sill, be sure that the grow area is facing into the room.

Step 2 - Creating the Conditions

In nature, mushrooms will fruit (grow) when they have the right level of oxygen and humidity.

Firstly, open the cardboard window on the front of the grow kit by pulling off the tab.

Next, using a clean knife, cut an ‘X’ into the plastic from one side of the window to the other. Don’t worry if you cut into the substrate a little, this can actually help the mushrooms grow!

Now that you’ve exposed the substrate to oxygen, it’s time to create the humidity! Simply mist the grow area once a day. Roughly 4 pushes on the spray bottle each time is about right - if it is in a warm area, more moisture may be required. It is important not to soak area and there is no need to peel back the plastic.

Step 3 - Mushroom Care

After 10 - 14 days, your Lion’s Mane mushrooms will start to grow. This is called pinning. Within another 7 -14 days, your Lion’s Mane will grow from tiny bumps on the surface to a full cluster of delicious mushrooms!

It is important to not let the mushrooms dry out at this stage. Keep misting the mushrooms each day and enjoy watching them grow.

Lion’s Mane will grow a bit more slowly than Oyster mushrooms but it is important to keep an eye on them.

Step 4 - Harvest

Your Lion’s Mane has been busy growing and you’re wondering when it is ready to harvest. The optimum time to harvest your Lion’s Mane mushrooms is when they start to produce white spines.

The mushrooms should be harvested as a cluster. Gently but firmly hold the mushrooms at the base and twist until they pop away from the block. Alternatively, use a knife to cut the cluster at the base. Congrats - you now have a delicious cluster of Lion’s Mane mushrooms to enjoy!

Step 5 - Repeat for more mushrooms!

The fun is not over - the kit should have enough energy for 2 more harvests!

Simply ‘clean’ the grow area by removing any small mushrooms or loose material. Then repeat the process by misting the grow area regularly.

With each round of harvest, it can take longer for the pinning stage to begin. A trick to speed this up is to place the kit in the fridge for 12 hours. The cold shock can encourage the kit to pin again (the mushrooms think winter is coming so they are running out of time to grow).

It also won’t hurt to be a little more generous with the level of moisture provided for the 2nd and 3rd flushes as the kit uses up some of its own moisture in producing mushrooms.

Step 6 - Disposing the Kit

Your kit has ran out of energy and finished growing mushrooms. To dispose of the kit, the carboard can be recycled and the plastic bag placed in general waste.

The substrate block can be composted or used in the garden as a soil improver. Crumble around plants or mix into compost to provide them with an extra boost of fungi.

You could even mix the substrate block with woodchips and you are likely to get additional mushrooms growing as they enjoy this extra food source. We like to spread our substrate / woodchip mix around new trees and hedgerows planted around the farm as it helps to retain moisture.

Frequently Asked Questions

  • For optimum mushroom yields, it is best to start the kit when you receive it. However, if you don’t wish to start the kit immediately, they can be stored in the fridge or a cold shed. We have grown kits that were stored in the fridge for 4 months with no issues, although we recommend starting them within 1 month.

  • Lion’s Mane mushrooms take a bit longer to grow than oyster mushrooms so you have to have some patience! The kit will take around 3-4 weeks to produce the first flush of mushrooms - but the wait is definitely worth it! This time can vary depending on the temperature and humidity.

  • Our Lion’s Mane grow kits normally last for 2-3 harvests.

  • Ideally you would spray the mushroom grow kit twice a day (around 5 squeezes on the spray bottle each time) but there are bound to be some days where this isn’t possible. We have tested lots of the kits in our home and sometimes forget or are away for a night or two – as long as you keep spraying consistently mushrooms will grow! Yields may be reduced if the mushrooms don’t get adequate moisture but you should still get mushrooms.
