What is the difference between boxed sets and grow blocks?
Both products contain the same 2.2kg growing block, but the sets also come with a gift box and a spray bottle, so they're ideal for giving as a gift.
Additionally, the varieties available in boxed kits are recommended for beginners, while you can also find more advanced varieties in grow blocks. Some of these will not grow well on a kitchen counter, they need a controlled environment. For best results, we recommend using a grow room or grow tent. If you don’t have the ability to control the temperature, choose a block that is suitable for your climate!
When growing on the kitchen counter, using grow blocks is just as easy as using boxed kits.
For detailed information, please read the Production block guide page, where you will find descriptions and tips for each variety. If you have any further questions, please read the Frequently Asked Questions page or write to us by email.
How many mushrooms will it produce?
Our production blocks are commercial sized. These 2.2 kg blocks will yield an average of 400–600 g of fresh mushrooms during the first harvest under ideal conditions.
Yield is significantly influenced by growing conditions, so please pay attention to the recommended environment for the given mushroom species, as well as the Product block in the guide as described to avoid disappointment.
There are of course differences between individual mushroom species – for example, some oyster mushrooms produce heavier fruiting bodies than other varieties – but with these large blocks you can definitely count on a nice, bountiful first harvest.
Since the blocks contain a high amount of nutrients, they can produce multiple crops. Typically, you can expect 2-3 crops, but if you are patient and persistent, you can even get more.
The first harvest is always the largest and fastest, but there can be a gap of up to several weeks between subsequent harvests.
Your first harvest is guaranteed by us!
If there has been no change 14 days after opening the block, send us a picture by email and we will help you, and if necessary, we will send you a new production block.
Extra tip: after a few harvests, the harvested block during the frost-free period It is worth placing it in a shady, protected place in the garden and keeping it moist. You can also place it shallowly in the ground and cover it with leaves or chopped straw. This „mushroom graveyard” can surprise you again with fresh mushrooms at the right temperature or after a heavy rain!
The classic
This mushroom is gray in name only! It is one of the most common oyster mushrooms worldwide, also called the late oyster mushroom. It is fleshy and elastic, and retains its texture even after cooking. It can be fried until crispy, especially when sliced thinly. Its flavor is mild, slightly nutty.
How was it made?
The heart of the kit is a straw growing block colonised with oyster mushroom mycelium. From an isolated mushroom culture, we first made a high-purity mushroom spawn on sterilized grain, then mixed it with chopped straw to create a growing block. Then we left the exciting part to you!
The mycelium that runs through the block is a living organism that - after digesting the available nutrients - is waiting for the right environmental conditions to form a fruiting body, the edible mushroom. The oxygen and moisture that come with opening the bag signal the mycelium that the time has come to grow mushrooms.
Guaranteed harvest
With regular and adequate moisture, our mushroom growing kits will produce reliably, up to 3-4 times. The first harvest is expected within 14 days of opening the bag.
Your first harvest is guaranteed by us!
If there is no change after 14 days of opening the kit, send us a picture by email and we will be happy to help, and if necessary, will send you a new kit free of charge.
Typically, each subsequent crop is slightly smaller than the previous one and appears after a longer period of time. It may take several weeks between each harvest, please be patient! How we recommend starting additional crops is explained in the Detailed User Manual .
A clever gift
Whether you want to please gourmets or hobby gardeners, the sight of mushrooms growing day by day can impress adults and children alike!
Warning: If you don't open it within a few days, refrigerate it!
Your kit contains a living organism, so we recommend that you open it and start spraying upon receipt. If you do not have the opportunity to do so, you can store it unopened in the refrigerator for up to 4 weeks. The metabolism of the mycelium slows down significantly during this time.
During prolonged storage or at room temperature, mold may start to grow inside the bag. This will not affect further use. If the mold is within reach under the area you cut, simply remove it.
A grow kit stored at room temperature for a long time will consume all available nutrients after a while and then it will slowly begin to decompose.
Worth evaluating
Take a photo of your harvest! We will send you an email 14 days after placing your order, allowing you to rate the stock. All photographic We will reward you with a 20%, non-expiry, freely usable and transferable coupon. Use it or pass it on!
Don't forget the user manual!
You will also find a short instruction on the back of the box, but for best results, we recommend reading the instructions before use. Detailed User Manual and the Frequently Asked Questions reading it too.

This was a great idea, I couldn't wait to get it. I didn't think it would be so simple: tear it, water it, admire it, pick it, eat it😍 My 6-year-old daughter and I couldn't help but admire how it grew/changed from hour to hour, we're already looking forward to round 2.
Thank you very much, we "raised" a divine pizza topping.

This was one of the best gifts we received! We admired how big our mushrooms had grown at every stage of the day. We had our first harvest, now we are waiting for the next one. My daughter doesn't like mushrooms, but since she could take care of them, she was even willing to eat them 🤩

I was very curious to see what it would be like, and I was not disappointed!
The package arrived quickly, preparing the kit was easy. It's nice that it comes with a spray bottle.
You can almost see it growing, but the growth is spectacular from night to morning. I will harvest the first batch now, and then continue growing. I wonder if there will be other types of mushrooms, because I would like to buy some of them too.

Great little kit! Easy to use and looks great on the kitchen counter. The first harvest was excellent, we are already looking forward to the second one!

The first batch developed in 4-5 days. Maybe I should have cut them all off and dried and stored the excess.

The child loved it, it had about 30 dkg of fruit on it.

I received it very quickly, perfect packaging. Easy care and very delicious harvest 😍😍 I will definitely buy again even if the current one doesn't produce anymore. I love mushrooms, my partner is a chef, so I always have to have them fresh 😍

The mushrooms grew, but they weren't nearly as big as in the picture. Which is okay. But the bigger criticism is that they only grew once instead of the promised 4-5 times.

Dear Aleksandra!
The size of the mushrooms depends mostly on the surface area exposed. A smaller surface area will produce fewer, larger fruiting bodies, while a larger surface area will produce more, smaller fruiting bodies.
The subsequent crops are smaller overall and appear over an increasingly long period of time, with several weeks between them.
It would be a unique case if it really only produced once, the block is probably just a little dry. As long as it doesn't have a greenish discoloration, there is a chance of another crop.
Based on the detailed instructions, we recommend starting by soaking: to do this, remove the bag from the box and place it, cut side down, in a bowl of cold water for 30 minutes. Then, drain off the excess water and wipe the bag dry, then put it back in the box and continue moistening as usual. Within 1-2 weeks, there is a good chance that a new crop will start.
To prevent it from drying out too quickly again, we recommend using a humidity tent: take a garbage bag or other plastic bag and make many holes in it, about 1 centimeter wide. Since mushrooms and mycelium both breathe in oxygen and release carbon dioxide, proper ventilation is essential! Cover the kit with the humidity tent. When spraying, pull it up, blow on the block (you can also spray a little water on the inside of the bag), and then put it back. Once baby mushrooms have appeared, fresh air is especially important, so remove the humidity tent and continue spraying as usual.
We believe that you will succeed with the above methods, just give it some time.
We welcome further feedback.

Unfortunately it hasn't arrived. They'll replace it. So it can't be a 5.
