Boxed set guide

In the box you will find a fully woven plant block and a spray bottle.
No preparation is required – just water and a bright spot.

1. Open it

Tear open the front of the box along the perforation.
For oyster mushrooms, cut an X-shaped incision in the plastic bag the full size of the window.
For porcini mushrooms, just cut a small 1x1cm X in the middle.
It's okay if you get a little into the block.

Leave the edges of the plastic bag in place – they help retain moisture.

2. Spray it

Fill the spray bottle with tap water.

Spray the cut area 2-3 times a day.
More often in warm, dry air.

The surface is ideal when small water droplets are visible on it, but water is not dripping off it.

3. Place it

Place the kit on a plate in a bright spot in your home, but away from direct sunlight.

Best place:

kitchen counter
near the sink
where it is in sight

Do not place it near a radiator or heat source.

3. When do mushrooms appear?

Within 5–14 days, tiny baby mushrooms (“pins”) will appear.

They then grow spectacularly within 2–5 days.

4. When do you harvest?

For oyster mushrooms, it is ideal when the caps are almost fully open but not yet bent upwards.
In the case of porcini mushrooms, when the "spikes" are well developed, but still flexible and bright white, 1-2cm long.

Remove the entire cluster at once, using a sharp knife close to the block. Then carefully remove any remaining mushroom parts.

Use you fresh mushrooms immediately or store them in a paper bag in the refrigerator, where they will keep for a few days.

5. How many crops are expected?

The stock usually bears fruit 2–4 times. The first crop is the largest.

After harvesting, let it rest for 2–3 days, do not spray.
Then start wetting again.

You don't need to cut the bag in a new place.

Several weeks may pass between each harvest.

6. If it doesn't restart

If no new crop appears after 3 weeks:

Soak the block in cold water for 30 minutes (cut side down)
drip it down
put it back in the box
continue spraying

7. When it is finally ripe

If the block shows no signs of life after 4 weeks or turns greenish, it's probably time to say goodbye.

But if you have a garden, you can give it a new life! Crumble it up as mulch in your vegetable or flower beds, or bury it not too deep in a shady spot in your garden. Then cover it with about 10-15 centimeters of organic material: straw, dried grass clippings, leaves or wood chips, and water it occasionally. A few weeks or months later (typically next fall or spring) you can enjoy another crop!

Used fruit blocks can be a great addition to your compost pile or worm bin. Worms love them!
