They become black, mycelium hyphae do not grow to them. What will happen to mushroom blocks with insufficient air humidity Humidity should be gradually raised to 80%. It takes some experience to learn to see this color change.Īt this stage, active gas exchange takes place and the temperature inside the block decreases. And only on the 7-8th day a whitish tint appears.īeginning mushroom growers think that the mycelium overgrows incorrectly or nothing happens to the straw at all. Straw can simply change its color – it becomes light brown with hints of yellow. Because of this, the substrate changes color, it becomes light cream or whitish (depending on the strain). The second phase of overgrowing of the mushroom blockįrom 6-7 to 9-10 days, mycelium hyphae grow along the substrate and intertwine with each other. Read About the problems and defects of the overgrowth of the substrate. It would be more correct to bring the heat treatment of the substrate to normal than to violate the incubation conditions.ĭuring hydrothermal treatment, the optimum moisture content of the substrate is 68-69%. Therefore, the mycelium overgrows worse, and the development of foreign microorganisms is possible, for which such an environment is more comfortable. In a wet substrate, not only water exchange is disturbed, but also gas exchange. They hope that excess moisture from the bags will evaporate into the air. And many mushroom growers lower the air humidity to 60% in the incubator. When the moisture content of the substrate is higher than the optimum, liquid collects in the corners of the bags. This is fraught with the development of bacteriosis or fungal diseases. Since moisture from the center of the block migrates to the surface. If the substrate is also slightly waterlogged, the underfilm layer of the substrate will be too wet. What happens to mushroom blocks with excessive moisture (air/substrate)Īt high air humidity (more than 90%), the amount of moisture released by the overgrown substrate will be less than optimal. This looks like asterisks, which is why many mushroom growers call the “asterisk stage”.įor normal gas exchange, it is necessary to keep the humidity in the room about 70-75%. The whitish hyphae of the mycelium move to the sides like strings and white spots of overgrowth appear. This stage lasts from the first to 6-7 days after inoculation.Īt the first stages, the growing mycelium actively breathes and releases moisture at the same time. Mycelium during growth in the substrate goes through several visually distinguishable stages.

Best humidity for mycelium growthĬonsider how to raise the humidity in an incubator containing mushroom blocks of the same age. If you have only one incubator that contains blocks of different ages, keep the humidity in it within 80-85% all the time. In the process of overgrowing mycelium, the humidity in the incubator must be increased.
