What is the difference between boxed sets, grow blocks, and XL grow blocks?
The boxed sets and regular grow blocks weigh 2.2 kilograms, and the sets come with a gift box and spray bottle, making them ideal for giving as a gift.
XL grow blocks weigh 4.5 kilograms, twice the size of regular blocks. Because they contain more substrate and nutrients, they can produce larger crops and provide a higher overall yield.
XL blocks do not produce faster, but they produce more abundantly.
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?
These 4.5 kg extra large blocks will yield almost twice as much as regular blocks under ideal conditions, with an average of 800-1200 g of fresh mushrooms in the first harvest.
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!
Long live the king
The devil's wheel, or king oyster mushroom, is a favorite of gastronomy worldwide. Unlike other oyster mushrooms, it has a thick, cylindrical stem and a small cap. It can be shaped and sliced easily. Its thick stem caramelizes particularly well when sliced and grilled, while maintaining its juiciness. Its texture remains stable even after baking. Its flavor is slightly nutty, umami, and its texture is extremely meaty and dense, which is why it is often used as a meat substitute.
Advanced species, please be sure to read the Product block in the guide found in the variety description.
Make sure that you can keep it at a suitable temperature below 20 °C during the entire growing period, because at higher temperatures the king oyster mushroom will grow weaker or in a distorted form.
How was it made?
The seed block is nothing more than straw or sawdust colonized with mushroom mycelium. From the isolated mushroom culture, we first prepared a high-purity so-called mushroom germ on sterilized grain, then mixed it with chopped straw to create a seed block. 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.
Storage
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.
