Growing mushrooms at home can be a fascinating adventure for both children and adults. It’s a hands-on way to connect with nature, learn about fungi, and enjoy fresh mushrooms right from your own space. This guide will walk you through every step of growing mushroom fruiting kits, with clear instructions in both Hebrew and English. The process is fun, engaging, and delicious!

Step 1 - Preparing the Fruiting Kit


Before you start, make sure your fruiting kit is ready. Most kits come as a block or bag filled with mycelium, the root-like structure of mushrooms.


Inspect the kit: Look for white, thread-like growth covering the block. This means the mycelium is healthy. If up to 10% of the kit lacks mycelium, that's fine - you can continue to the next step. If there are larger areas without mycelium, your kit needs a little more time to finish incubating. This is what you do:

  • Do not open the kit's bag

  • Place the kit in a space that is dark

  • Maintain 20℃-24℃

  • Check on your kit every 3-4 days

  • Pro-Tip: With a marker, trace around the position of the mycelium. You will be able to see how quickly it advances over the substrate.

  • Once the kit is ready, proceed to the next step ⇙⤦

  • Open the packaging and remove any air: Make a small cut in one of the top corners of the bag. Fold the excess bag neatly to push out the air, and tape it to the top or side of the bag. Make sure the opening you cut is now sealed.

    • Pro-Tip: The mycelium will look for fresh air. Mushrooms will grow out of any opening in the kit.

  • Cut openings in the bag for mushrooms to grow: Choose where your mushroom will grow!

    • Choose an area that has consistent mycelium

    • Cut an opening in the bag over the area you have chosen

  • You can Cut an "X" or a line "/" or a "U"

  • Don't cut too deeply into the mycelium. The goal is to cut the bag.



Step 2 - Preparing the Environment


Mushrooms need the right environment to grow well. They prefer cool, humid, and shaded places. Choose a place where these conditions are possible:


  • Temperature: Keep the area between 18-24°C (65-75°F).

  • Humidity: Aim for 80-90% humidity.

  • Pro-Tip: Take a large, see-thru, plastic bag and place as a tent over the kit. Cut several holes in to so that air can pass. Use a spray bottle 3 times a day to mist water the kit daily. Mist the inside of the large bag. Do not mist the mushrooms directly (they dislike it).

  • Light: Indirect natural light or low artificial light works best. Avoid direct sunlight.

  • Airflow: Good ventilation is important but avoid strong drafts.



Step 3 - Choosing the Growing Location


Pick a spot in your home that suites the environment needs.


  • A shaded windowsill with indirect light

  • A cool kitchen corner

  • A bathroom with a window (humidity is often higher here)

    • Pro-Tip: If you have a humidity sensor (hygrometer) - place it under the tent, and monitor the humidity for best results


Make sure the spot is safe from pets and young children who might disturb the kit.



Step 4 - Pinning and Fruiting


After a few days, you will see tiny mushroom pins forming on the block. This is the exciting part!


  • Keep misting: Spray water gently 2-3 times a day to maintain humidity.

  • Watch for pins: The mycelium with thicken and Small bumps will appear; these will grow into mushrooms. The pins will often be white or brown, and can also be blue, pink and yellow for some species.

  • Avoid overwatering: Too much water can cause mold.

    • Pro-Tip: If withing a week you don't see pinning, check your conditions and try lowering the temperature.



Step 5 - Picking the Mushrooms


Congratulations! When the mushrooms grow to a good size, it’s time to harvest.


The Lion's Mane will reach it's full size, and "teeth" will start to extend.

Pick while still white and the teeth aren't too long.

The top of the Lion's Mane will feel spongy and soft

The cap is slightly curled down, or has flattened.

Pick before the cap curls upwards

Harvest before the cap completely flattens

  • Look for caps that have fully opened but are not too old or slimy.

  • Twist gently at the base or cut with a clean knife.

  • Harvest regularly to encourage more growth.

  • Remove old mushrooms from the kit, as they may hinder future growth.



Step 6 - Resetting the Kit


After harvesting, your kit can produce more mushrooms if you care for it properly.


You can fruit again from the existing opening

  • Pro-Tip: Seal the original cut you made with tape, and make a fresh cut on another side

  • If maintianed well, your it can give 2-3 "flushes" of mushrooms.

  • Continue fruiting until the kit has lost about 50% of it's weight.Then follow the next steps:

  • Soak the block in cold water for 12-24 hours.

  • Drain excess water and place it back in the growing spot.

  • Repeat misting and care as before.


Step 7 - Eating Mushrooms


You now have your very own home grown mushrooms. Find a recipe for the species you have grown, and make a delicious meal.

Here are some steps to take before you cook the mushrooms:


  • Cut away any substrate attached to the base of the mushroom

  • Do not wash mushrooms. You can gently wipe the mushroom with a damp paper towel to remove dirt.


Growing mushrooms at home is a rewarding experience that teaches patience and care. Whether you are a child curious about nature or an adult looking for a new hobby, mushroom fruiting kits offer a simple way to enjoy fresh fungi. Try it yourself and watch how a small block turns into a lively mushroom patch!


Ready to start your mushroom adventure? Follow these steps, and soon you’ll be picking your own delicious mushrooms at home.
