To stop its development is as easy as disinfecting a sharp knife and removing the affected area. It usually comes out because of high temperature and too low humidity and, if you don’t stop it, it will colonize the whole substrate. Overlay is a fungal strain that looks like mycelium, but has a more cottony texture. It usually appears in crops with excessively high relative humidity, but can also develop due to poor ventilation. It forms thinner filaments than the mycelium and can spread throughout the substrate in one or two days. It is similar to mycelium, although greyer in colour, hence the difficulty in appreciating it by new users in the production of mushrooms for self-consumption. Picture showing Trichoderma Harzianum infection on agar*Ĭobweb is another fungus that often destroys crops, firstly because it is not easy to identify if you are not experienced, but also because of how quickly it spreads. Poor hygiene, flies or poor sterilization can cause these contaminants to appear during the colonization or production of magic mushrooms. It is so difficult to eliminate that it is not worth fighting against it, so we recommend that as soon as you see any green area, remove that tupper from the crop, as it is easy to spread with the help of its spores. At first a mycelium-like mould emerges, but when it releases the spores it turns green and spreads really fast throughout the substrate. When this happens it is usually due to a Trichoderma Harzianum infection, although the symptoms are very similar to those of Aspergillus and Penicillium. Green mould (fungus) is the most common infection, the mushroom bread turns green and a white foam usually appears on top. □ Most common contaminations of magic mushroom breads But by growing several crops (Flush) it is possible to have them, so it is important to be aware and prepared. Mushroom cultivation kits come sterilized and prepared, so there should be no problems due to contamination. Insect pests, like bacteria, with proper sterilization and hygiene can be prevented to a great extent. This is normal, because mushrooms are fungi, and when we prepare their ideal growing medium, we are basically facilitating the appearance of these beings.īacteria, on the other hand, can be largely avoided by good sterilization of the substrate, so they do not usually contaminate the hallucinogenic fungi crop if you are careful. Mushrooms spread by forming nets of hyphae, a kind of small threads, and represent the highest percentage of contamination during indoor mushroom cultivation. The most frequent contaminating agents can be divided into 3 groups: fungi, bacteria and insects, being fungi the most frequent ones. ✅ Which are the most common contaminants in magic mushroom crops? If you are not sure about a possible contamination in the culture medium of the magic mushrooms, you can send us a picture, we will try to help you as soon as possible. If you have doubts that one of them may be contaminated, the best thing to do is to remove it carefully as soon as possible, so that it does not spread to others. If you have several tuppers or culture vessels in the same space infection can go from one to the other. Mushroom kits for sale in Pevgrow are perfectly sterilized, so it is difficult for them to become contaminated, but if they do, the best thing to do is to put them in a garbage bag and throw them away. The first thing is to get rid of it, firstly because it will no longer produce anything profitable and secondly because it can contaminate other crops. □ What to do when a hallucinogenic mushroom crop is contaminated? Image of a mycelium contaminated by mould in a homemade magic mushroom crop* Hygiene and care when handling mushroom bread is crucial, as well as keeping it away from pets and other contaminating vectors. Any external agent entering the culture medium can be a threat, so an adequate disinfection and sterilization is critical. When we sterilize a substrate we leave it clean of contaminants, but the absence of other agents means that the first to enter the environment will flourish without competition, something that does not happen in nature thanks to the balance between species.Ĭontamination can come through the air, water, tools used, our clothes, etc. This means that in nature there is a balance between bacteria, fungi and other organisms and microorganisms, but to produce magic mushrooms indoors it is necessary to prepare the environment, which causes biological imbalance and possible infections. There are several reasons why they can be contaminated, the most important being that we grow them artificially. And don't let them ask you what to do with your growth.
