Oyster mushroom mycelium on wooden plugs is an excellent choice for anyone who would like to grow delicious, nutritious mushrooms at home in. a natural way. Plug spawn makes cultivation straightforward and reliable.
You can cultivate Oyster mushrooms in your home garden, orchard, or even in a damp cellar – without any special knowledge or experience.
The Oyster mushroom (Pleurotus ostreatus) is one of the most popular mushroom species, valued for its:
firm, meaty texture and delicate flavour,
naturally occuring protein, fibre and B vitamins,
long-standing tradition of culinary use.
Beyond its culinary appeal, it is appreciated for its nutritional composition and its long history as part of the traditional diet in many cultures.
For a successful cultivation you will need:
hardwood logs (e.g. beech) – fresh, healthy and undamaged,
drilled holes into which you insert mycelium-infused wooden plugs,
a shaded and humid location – in your garden, cellar or tunnel.
In warm conditions, the mycelium gradually colonises the wood and draws nutrients from it. Once sufficiently developed, it begins to form mushroom primordia.
The first harvest usually appears in spring or autumn, depending on weather conditions.
With our Oyster mushroom spawn, you can enjoy growing mushroom naturally – simple, wholesome, and full of flavour.
Perfect for anyone who values high-quality food straight from their own garden.
Curious to try more? Check out our Shiitake mycelium on plugs, ideal for those who enjoy a rich, robust flavour.
Logs inoculated with Oyster mushroom mycelium can withstand low temperatures – down to –20 °C – without damage.
This cultivation method is:
From one cubic metre of wood, you can expect approximately 60 kg of mushrooms – grown without chemicals or artificial additives.
✅ Fresh, organic mushrooms grown locally
✅ Free from pesticides and other harmful substances

Hello, Almost two years ago, you advised me on choosing the right product and dosage for my father after he suffered a traumatic brain injury from a fall off a ladder. I would like to thank you and share our experience.
After he started taking Hericium according to your recommendations, we quickly noticed that his thinking became clearer, his speech improved, and he seemed more present and engaged.
At first, we weren’t sure whether these changes were simply part of his natural recovery. However, after nearly two years, the difference has become obvious. We notice it most clearly towards the end of his break from taking the supplement and then again when he starts using it again. Now that he is no longer taking any other supplements or medications, we believe these changes can only be attributed to your product. Thank you very much for your advice and support. Best regards, Uroš
Dear GOBA Team, I would like to sincerely thank you as a very satisfied customer.
Everyone in our family is a great animal lover. Besides our rabbit, we have two dogs. The younger one is only nine months old, while our older female dog will soon celebrate her 17th birthday.
A few months ago, we noticed that during our regular daily walks she seemed somewhat confused. She also began experiencing digestive issues, which significantly shortened and limited our daily activities together.
Following your recommendation, we started giving her your FOCUS supplement. We noticed the first positive changes quite quickly—after about two weeks. She was in a better mood, more attentive, had more energy, and her digestion also improved. We are happy to continue using your other products as well and are already looking forward to many more wonderful adventures together with our dogs.

Our cat Max will soon be 10 years old. I sprinkle GOBA VITAL® on his food and he accepts it without any problems. After introducing it, we noticed that he was more lively and playful, which made us very happy. We also pay special attention to his diet, as he has a sensitive digestive system, so it is important to us that the products are well tolerated. We have included GOBA VITAL® as part of his daily routine. – M.F.
If you store fruit or potatoes in a cellar and the room is not sufficiently ventilated, the gases emitted by the fruit can have an undesirable effect on the fungi, resulting in deformation of the hats.
It is best not to push the plugs deeper into the trunk, but to keep the end of the plug flush with the surface of the bark. Alternatively, the holes in the trunk can be much longer than the plug itself – this allows the mycelium to penetrate even faster. In our case, even with paraffin, the holes are not greased and the mycelium outgrows them well.
In the beginning, when the trunks are in the overgrowing stage, they can be kept in living spaces. Later on, when the fungi have taken over, it is better to keep them outdoors because of the spores they release into the environment. Large amounts of inhaled spores can cause allergies in humans.
No. A cracked trunk means that another fungus species has already overgrown it and will most likely prevent the fungus you are about to plant from growing on the trunk.
Mycelium needs very little oxygen to grow, so the film does not hinder its respiration and does not need to be removed from the stems. Over time, it will fall off on its own.
The cultivated mushrooms whose spawn we produce and sell here are rot fungi, not parasites. So there is no need to worry about them attacking healthy trees in the vicinity.
Natural light can be successfully replaced by artificial light. However, mushrooms exposed to UV light have a much higher vitamin D content.
Trunks inoculated with mycelium from shiitakes, oystercatchers, winter parakeets, white oystercatchers and honeysuckles can be kept outdoors all the time, as these species are frost-tolerant. Ganoderma lucidum is sensitive to frost and it is advisable to protect the trunks inoculated with it from frost.
Protect the trunks only at the cut ends, not over the whole trunk. This is because you only need to prevent pests from gaining access and drying out the part of the trunk where you have ‘damaged’ it by applying mycelium to it.
There can be about 2/3 of the stalls in a room, because we need space to walk between them. This means that in a room of dimensions 8m x 2m = 16m x 2/3 = 10.7 square metres of standing room. The racks usually have four shelves (the shelf spacing should be about half a metre), which means 10.7 x 4 = 43 square metres of functional space. Approximately 9 growing sets can be placed per square metre of shelving, which means that in a space of 8 m x 2 m, 9 x 10.7 x 4 = 385 growing sets can be placed on the shelving. One kit will grow about 0.7 kg of mushrooms over the entire growing season (which can last up to six months), which means that you can produce 385 x 0.7 kg = 269 kg of fresh mushrooms in half a year in such a space.
You can protect the ends of the trunks with foil only, but in this case you need to protect the trunk from sunlight, as the trunk gets very hot under the foil.
You can apply mycelium to wood at any time. If you use mycelium on cereal grains and apply it to wood before winter, you need to protect it well from rodents and birds, as they are very keen to eat it. When applying mycelium to wood in the run-up to winter, bear in mind that mycelium growth will stop during the winter months and resume in the spring. The overgrowth period will increase proportionately.
In principle, wood harvested during the dormant season is preferable. It will yield a few percent more mushrooms. If you do not grow mushrooms on a large scale, the difference in yield will not be so great that you will have to choose and wait for the right time to cut the trees. We just graft the trunks when we have the wood to do so.
In our experience, beech trunks 40cm in diameter and 80cm long will produce mushrooms twice a year for up to eight years. However, this depends mainly on the type of mushroom you want to grow and the type of wood used.
One cubic metre of wood can yield up to 64 kg of fresh mushrooms over a growing season of a couple of years.
With 300 plugs, you can make about a quarter of a cubic metre of wood.
One cubic metre of trunks produces a mass of fresh mushrooms equivalent to up to 20% of the dry weight of the wood over the entire growing season (which lasts several years). That is to say, one cubic metre of average wood (850 kg dry weight, which must be reduced by a third because there is so much space between the trunks) can yield 112 kg of fresh mushrooms (applies to beech oyster mushrooms).
We do not have good experience with the use of fruit tree stumps for mushroom cultivation, as they are often already cracked inside or resinous. If you do decide to grow mushrooms, we recommend you try beech oyster mushrooms, which have aggressive growth and will cope best with the situation.
Those “strange” fungi were probably already in the trunk before you introduced the mycelium. This sometimes happens with trunks taken from trees that are damaged, have cracked side branches or are old (trunk diameter greater than 30 cm). In such trees, many fungi are already present in the centre of the trunk, waiting for the day when the tree falls down and they start to sprout from it. It is very difficult to believe that the mycelium we have sold you is dead, because we grow it from cultures of known and regularly checked quality, we keep it at a low temperature all the time to prevent it from ageing and dying, we renew it, and it is always grown in completely sterile conditions to prevent contamination by bacteria or mould.
The rate of emergence depends in principle on the “maturity” of the substrate. In principle, however, the mushrooms emerge at room temperature within 14 days of opening the kit and reach their final size within a few days.
The spores released by the fungi during growth may accumulate on the crops themselves, but in our experience they will not germinate or cause other damage.
Conventional lamps are sufficient for lighting and additional lighting with a UV lamp is not necessary.
