Mushroom farming can be a fun hobby for people of all ages. It can also be a great way to grow food in a small space!
Most mushrooms prefer humid environments with plenty of oxygen and minimal direct sunlight. Luckily, most home growers can replicate these conditions in their own homes.

With psilocybin mushroom grow kits, enthusiasts can embark on their journey into the realm of psychedelic mushroom cultivation with confidence and ease.
1. Substrate
Having the proper mushroom growing substrate is a key part of any successful crop. In general, mushrooms prefer to grow in a rich, dark and moist material that has good nutrients for the fungus to thrive in. The substrate can be almost any material, including straw, cardboard and coffee grounds. But to keep the process as clean as possible, the materials must be pasteurized or sterilized to reduce contamination by mold and bacteria.
Those contaminants may not seem like much of a threat to the uninitiated amateur mushroom cultivator but they can easily outperform and overtake mycelium, the fungus that makes mushrooms. This can lead to an unstable growth environment where the mushrooms are more prone to infection and disease than they should be. Pasteurizing or sterilizing the substrate reduces contaminants and creates a healthier environment for the fungus to thrive in.
Mushroom substrate can be pasteurized and sterilized using a variety of techniques. Some methods involve heating the material to a temperature that kills any microorganisms, while others use chemicals to treat the substrate to kill fungi and bacteria. The pasteurization and sterilization of substrate can be done in a kitchen oven, in the microwave or even in boiling water. For a more organic approach, the substrate can be soaked in a solution of hydrated lime and peroxide.
For most beginners, a straw or wood substrate is the easiest to work with. This can be soaked in warm or hot water and mixed with the mushroom spawn before being placed into a container for cultivation. For more advanced growers, they can make their own sachets or trays by placing the spawn into sterile 14×16-inch flats that look like seed flats.
More sophisticated mushroom farmers can grow on a more complex substrate made from ingredients like coco coir and vermiculite. The former is a material that’s created from ground-up coconut shells and husks and is available at most garden stores. The latter is a yellowish-brown mineral that helps retain moisture. This can be mixed with the straw to provide a more nutritious substrate for some species of mushroom.
2. Inoculation
Inoculation is the process of adding spores or spawn to a nutrient medium for mushroom growth. Depending on the type of mushrooms you grow, inoculation may require sterile conditions. Inoculation is essential for growing mushrooms outdoors on logs or indoors on substrate blocks. It is also required for inoculating bulk substrates such as straw, pasteurized compost or wood chips.
Spore syringes, liquid culture or grain spawn can be used to inoculate a substrate. Make sure to use high-quality, sterilized spawn or culture purchased from a reputable supplier. In addition, make sure that the spawn or culture is properly hydrated and is at room temperature. Regardless of which method you choose, always work in a clean environment.
If you are growing mushrooms in a container, such as a plastic bag or cardboard box, it is important to seal the substrate with a food-grade wax to prevent contamination. There are several different types of wax available, including cheese wax, beeswax and paraffin wax. It is recommended that you choose a vegetable-based wax such as cheese wax because it does not contain petroleum. The disadvantage of using paraffin wax is that it can crack at very low winter temperatures, which may impact the yield of your mushrooms.
For a log-inoculated mushroom farm, it is recommended that you inoculate the logs as soon as possible after they are felled. This will help maximize production per log.
The traditional log inoculation method involves drilling holes in the logs, inserting plug or sawdust spawn and sealing them with wax. It is also common to use the “totem” or pillar method of inoculation, which is two or more 10 – 12 inch (20 – 30 cm) diameter logs stacked vertically and sawdust spawn sandwiched between them. Plug spawn can be used in these methods, but sawdust spawn is more effective and colonizes 30% faster than plug spawn.
Grain spawn can be used to inoculate bulk substrates and fruiting logs for outdoor or indoor mushroom cultivation. It is best to inoculate grain spawn under sterile conditions, which means that it should be done in a clean room or in a laminar flow hood.
3. Monitoring
Mushroom farming is a delicate process that requires a high level of awareness in order to produce quality mushrooms. This includes the monitoring of temperature, humidity and carbon dioxide levels. Monitoring these factors allows for the farmer to adjust their growing environment accordingly, resulting in a bountiful harvest. For example, if the level of CO2 is too low in the growing environment, this can cause the fruiting bodies to not develop properly. This can result in poor growth and yield, as well as the development of harmful bacteria or fungi.
The amount of light exposure that mushrooms receive also has a significant impact on their growth and development. Mushrooms need darkness to grow and therefore require minimal light exposure during the initial stage of cultivation. However, during the fruiting phase, mushrooms need moderate levels of light to develop and mature. This is why it is important to monitor the levels of light exposure during this period.
It is also important to monitor the pH level of your mushroom growing medium. Ideally, the growing medium should be slightly acidic and not too alkaline. This can be accomplished by testing the pH level of your growing medium regularly with a meter or kit.
4. Harvesting
Mushrooms are having a moment partly due to their reported health benefits including brain health and immune system support. Growing mushrooms at home is an easy, family-friendly project that requires minimal space and no gardening experience. Mushroom farming is an incredibly rewarding hobby that can be very satisfying. However, it is also a hobby that is not without its share of ups and downs. From bountiful harvests to green mold and spoiled batches, it’s important to understand what is involved before diving in.
Mushroom growth is very sensitive to environmental conditions, particularly temperature and humidity. It’s essential to keep an eye on both of these conditions with a thermometer and hygrometer. If the environment becomes too warm or too cold, it can stunt mushroom growth or cause the development of harmful bacteria and fungi.
In addition to monitoring environmental conditions, it’s important to monitor the pH level of your substrate regularly. Most types of mushrooms grow best in a slightly acidic environment, with a pH between 6.5 and 7.5. If the pH level of your substrate is too high, it can interfere with nutrient absorption and lead to poor crop yields.
When you’re ready to harvest, the process will vary based on the type of mushroom that you’re cultivating. Button mushrooms, for example, should be harvested as soon as their caps start to open. Once they’re mature, they can be cut from the stem using a sharp knife. Be careful not to disturb the surrounding fungi or the mycelium underneath, as this can cause them to spoil.
Morel mushrooms, on the other hand, can take up to 18 months to appear. The most common method of cultivation involves drilling holes along the length of a log and inserting an impregnated dowel in each one. This dowel is then sealed with wax (if needed) and placed in a shady spot where it will remain moist. Once the first flush appears, the log can be moved to a fruiting chamber and the process repeated as needed. Mushrooms require darkness to develop, so the room should be dark and well ventilated.
