This product includes two Grow Kits of your choice.

Satohuone's Grow Kit allows you to easily grow your own mushrooms indoors. The package includes a pre-incubated substrate of the mushroom of your choice. All you need is a spray bottle for maintaining moisture.

Grow Kit package dimensions: 12cm x 10cm x 22cm + handle 6cm. Weight approximately 1.2 kg.

Instructions in a nutshell:

1. Open the window and cut an X-shaped slit through the plastic.

2. Keep the slit moist by spraying it 2-3 times a day.

3. Harvest the mushrooms and enjoy!

4. Compost the spent substrate.

It's that easy! However, for the best results, it is recommended to read the detailed cultivation guide provided below.

Grow Kit Cultivation Guide

With Satohuone's Grow Kit, you'll get mushrooms as long as you remember to keep it moist at all times. Though by following these instructions, you'll achieve the best possible results. At the end of the guide, you'll find answers to frequently asked questions and instructions in case you don't see any mushrooms even after four weeks.

1. Storage, before starting

The Grow Kit contains a living substrate that doesn't last forever. It's recommended to start cultivation immediately after receiving the package. If you can start within a few days of receiving the package, keep it at room temperature until then. Otherwise, store it in the refrigerator for up to 2-3 weeks.

2. Growing environment and placement

Mushrooms need warmth, light, moisture, and oxygen to grow. When grown indoors, you don't need to worry too much about warmth and light; normal room temperature and ambient light in the apartment are sufficient (avoid direct sunlight). A slightly cooler porch is also suitable; the optimal temperature is 15-18 degrees Celsius. Oxygen is also sufficient as long as the Grow Kit is placed in an open area, such as on a kitchen counter (avoid heat sources such as ovens or dishwashers). Don't enclose it in a cabinet or shelf. Moisture is the variable that requires the most attention because mushrooms need continuous hight moisture to grow.

3. Starting cultivation

To start the cultivation, tear open the cardboard box window along the dashed lines. Underneath, you'll see the substrate covered with white mycelium. If there are cracks in the substrate from transportation, let the substrate rest at room temperature for a couple days before starting. Use a sharp knife to make a large (5-10cm) X-shaped cut through the plastic into the substrate. On Lion's Mane make the X smaller (2-3cm). Make sure the flaps of the X are separate. Sometimes, the substrate may be tightly stuck to the plastic, in which case, use the tip of the knife to separate the flaps from the substrate. However, always leave the flaps down to better retain moisture in the cut.

4. Moisturizing

Once the X is cut, all you need to do is maintain moisture until the mushrooms are ready to be harvested. A regular spray bottle works for this purpose (the finer the mist, the better). Spray clean water onto the cut at least 2-3 times a day. Don't open the flaps, just mist the X. You'll get the best results by spraying more often, especially in winter when indoor air humidity is very low, you may need to spray every few hours. Lion's mane needs less misting in general, and in the autumn when ambient humidity is high, you can mist just once or even skip the whole misting. The most common reason for failing is inadequate moisture maintenance. Avoid spraying too much water at once because excess water will just drain and accumulate at the bottom of the plastic bag or cardboard box. A few precise sprays from the spray bottle are enough, depending on the spray bottle. Protect the surface below if necessary.

If spraying multiple times a day seems challenging, you can create a moisture-retaining hood. Make small (about 2cm) holes all over a regular empty plastic bag and place it over the Grow Kit as a hood. Spray the inside walls of the bag with water at least twice a day. If you use a transparent bag, you can easily observe the formation of mushrooms and the moisture level inside the bag. You can also leave the top of the tear window intact and place the hood on it. When the mushroom pins start to grow larger, remove the hood so that the mushrooms receive enough oxygen, and continue spraying directly onto the mushrooms.

5. Waiting

Mushrooms usually start forming about 7-14 days after starting, assuming that moisture has been maintained throughout this time. Sometimes it happens faster or slower. It's important to continue moisturizing patiently. If you suspect that the substrate has dried out during the process, continue spraying. In this case, you may have to wait a little longer. Once the mushrooms start to grow, it only takes about 4-5 days until they are fully grown. Lion's mane grows a bit slower to maturity. They still need plenty of moisture until they are harvested. If you don't see any mushrooms after four weeks of starting, and you've been maintaining moisture well throughout that time, see the advice at the end of the guide.

5. The Reward

The wait is rewarded when you see the tiny pins growing into large and delicious mushrooms, and you get to harvest your very own mushroom crop. You can recognize mature oyster mushrooms by their initially curved caps straightening out. Oyster mushrooms often grow in clusters. Harvest the entire cluster at once by gently twisting it off the substrate. Matured Lion's Mane has it's signature "teeth" or "hair" about 0.5-1cm long. Cut off any remaining substrate, and the mushrooms are ready to be used. You can slice and fry the mushrooms in oil, seasoning with salt and pepper, or use them in various dishes such as risotto, ramen soups, or stir-fries. Note that the stem of the oyster mushroom is firmer than the cap, so it may not be suitable for the same dish. Mushrooms can be stored in the refrigerator in a paper bag for about a week. After harvesting or even before, white "fluff" may form on oyster mushrooms, which is natural growth and completely harmless. Growing conditions significantly affect the yield of the Grow Kit, but the typical yield (for the first harvest) is 150-300g of fresh mushrooms.

5. After the harvest

Once the mushroom crop has been harvested, you can try for another flush by just keeping on moisturizing. A second crop typically takes 2-4 weeks and is smaller than the first crop (unless the first crop was very small due to unoptimal conditions). A second crop may be more successful if you rehydrate the substrate after the first harvest (instructions at the end). If you don't want to attempt a second flush, you can compost the used substrate, use it as a soil conditioner or mulch in the garden, or try inoculating it into bulk substrate material such as straw pellets (for oyster mushroom) or hardwood pellets (for lion's mane) and try your luck with outdoor cultivation (from spring to autumn).

What if the mushrooms just don't appear?

Our mushroom mycelium is very robust and will find its way to mushroom formation as long as the conditions are right. The importance of maintaining moisture cannot be overstated; the most likely reason you don't see any mushrooms is the surface of the substrate drying out. So, read the guide carefully and follow the instructions. If the substrate dries out in between, don't give up. Continue moisturizing and wait patiently. Patience is key.

If, however, you still don't see any mushrooms growing after four weeks (with successful moisture maintenance), you can try rehydrating the substrate. Remove the substrate from the cardboard box and submerge it in water with the cut facing downwards for 20 minutes. Let any excess water drain from the bag, then put it back into the cardboard box. Continue spraying according to the instructions from the beginning, even though the substrate has just been rehydrated. Follow the guide as usual. If you don't see any mushrooms 4 weeks after rehydration, please contact antti@satohuone.fi, and we'll look into it together.

Enjoy and best of success with your cultivation!
