Best Time To Pick Cubensis Mushrooms

when to pick cubensis mushrooms

Knowing when to harvest Psilocybe cubensis mushrooms is crucial to maximising future flushes and getting the most out of your crop. The best time to harvest is just before the veil breaks, usually between 5-12 days after the first pins pop up. The veil is a thin membrane on the underside of the cap that keeps the spores in the mushroom. When the mushroom is mature, the veil tears, the spores are released, and the mushroom begins to wilt. If you harvest too late, the mushrooms will be covered in black spores, which can be toxic. However, if you harvest too early, the mushrooms will not have reached their full potential.

Pick before the veil breaks

Picking Cubensis mushrooms at the right time is crucial for optimal potency and yield. One of the key indicators to look out for is the veil, a delicate membrane that covers the gills of the mushroom. It is important to pick Cubensis mushrooms before this veil breaks.

The veil serves as a protective barrier for the gills, which are the thin, radiating plates under the mushroom cap where spores are produced. When the mushroom is young and the gills are still developing, the veil keeps them moist and protected from potential damage. As the mushroom matures, the veil will naturally break, allowing the spores to be released and dispersed.

For those cultivating and picking their own Cubensis mushrooms, it is essential to monitor the veil closely. The ideal time to harvest is when the veil is still intact but easily removable, indicating that the mushroom is mature enough for picking. If the veil breaks prematurely, it can result in a reduced yield and lower potency of the mushrooms.

To ensure a successful harvest, keep a close eye on the mushrooms as they approach maturity. The veil should be fully formed and covering the gills, but still thin and delicate. Gently

Harvest when the cap opens

The best time to harvest cubensis mushrooms is when the cap opens and flattens, taking on the shape of an umbrella. This is usually the same day the veil breaks or a few days after. The veil is a thin membrane on the underside of the cap that covers the gills and keeps the spores in the mushroom. When the mushroom is mature, the veil tears, and the spores are released, ready to grow the next generation of mushrooms.

If you are growing mushrooms indoors, it is undesirable to let the spores release onto the mycelium cake, as it will produce far fewer mushrooms in the subsequent flushes, if any at all. Therefore, it is essential to harvest cubensis mushrooms right before the veil tears and the spores are released.

The veil is located on the underside of the cap, and on juvenile mushrooms, veils are fleshy and light-coloured – usually grey-white. When the time comes for them to tear, they often darken and begin to sag. The mushroom will then continue to grow in size but will not develop any more psilocybin or psilocin.

Several studies and reports suggest that mushrooms produce less psilocybin relative to the mushroom's total weight as the mushroom grows, with the peak of active compound production ending around the time of the tearing veil. Therefore, it is best to harvest cubensis mushrooms when the cap opens, but before the veil tears and the spores are released.

Avoid mushroom maturation

Mushroom cultivation is a delicate process that requires careful attention to detail. Here are some crucial tips to avoid mushroom maturation and ensure a successful harvest:

Sterilization and Contamination Prevention:

Maintain a sterile environment to prevent contamination, which can ruin your crop. Sterilize your equipment, including syringes, needles, and scalpel tools. Regularly check the pressure when using a pressure cooker for heat sterilization. Additionally, ensure proper ventilation in your workspace once you've finished working with spores.

Temperature Control:

Aim for a temperature slightly below the optimum level to avoid cooking your mycelium. The temperature in your substrate should not exceed the air temperature in the room. Keep your fruiting room within the optimal range of 57° to 62°F (13.9° to 16.7°C) during cropping.

Moisture Management:

Maintain adequate moisture levels. The substrate should be damp but not wet. Squeeze it gently, and a few drops of water should be released. Stop watering when the pin initials are forming to avoid excessive moisture, which can cause mushrooms to grow below the casing's surface.

Harvest Timing:

Harvest your mushrooms just before the veil beneath the cap tears. The veil is a thin membrane that covers the gills and holds the spores. As the mushroom matures, the veil darkens and starts to sag before tearing. Harvesting at this stage ensures the highest potency and prevents spore release, which can reduce future mushroom growth.

Ethical Harvesting:

Be gentle during harvesting to avoid damaging the mycelium, which can impact subsequent flushes. After each harvest, replenish moisture and maintain sterility to encourage further growth.

By following these practices, you can avoid mushroom maturation and promote healthy, sequential flushes, ensuring a bountiful harvest.

Observe the veil colour

The veil is a thin layer of tissue that covers and protects the developing spores on the gills or pores located underneath the cap of a mushroom. The veil is typically white or greyish in colour when it has not been triggered. When the mushroom is mature, the veil tears and the spores are released, ready to grow the next generation of mushrooms. The veil is a key indicator for cultivators regarding the timing of harvest.

For Psilocybe cubensis, commonly known as magic mushrooms, the veil is a well-developed white membranous ring whose surface usually becomes the same colour as the gills because of falling spores. The veil is located on the underside of the cap and covers the gills. On a juvenile mushroom, veils are fleshy and light-coloured – a sort of grey-white usually. When the time comes for them to tear, they often darken and begin to sag. The gills will turn from a pale colour to a dark purple-brown. When the gills are fully dark and the veil has broken, the mushroom is ready to be harvested.

The optimal time to harvest mushrooms for quality is when the veil has just broken or is about to break. This stage ensures the mushrooms are mature yet not degraded, maintaining their potency and flavour. Harvesting at this time ensures the mushrooms are at their peak for culinary or other uses, capturing the full flavour and potential biochemical compounds of interest.

Until you have a little experience, you should always harvest mushrooms while the veils are still lightly coloured. As soon as you see any sign that they may be darkening, the time to harvest has arrived. If you wait too long, the mushroom will soon start to die, as it has fulfilled its purpose. It will darken, appear to wilt, and eventually break.

Dehydrate your harvests

Dehydrating your cubensis mushrooms is a crucial step in preserving their quality and extending their shelf life. Fresh mushrooms can begin to decay within 24 hours of being picked, so it's important to act quickly. Here are some detailed instructions to guide you through the process of dehydrating your harvests:

Preparation

Before you begin dehydrating, it's important to clean your mushrooms to remove any dirt. You can use a damp paper towel, a mushroom brush, or quickly rinse them under cold running water. Select only the freshest mushrooms, as any signs of decay, mould, or bruising can affect the entire batch during drying.

Equipment

You'll need a food-grade dehydrator with drying trays or racks that allow for good air circulation. Mesh dehydrator liners can be useful to prevent small mushrooms from falling through the racks. Alternatively, you can use a DIY approach by cutting a cheap fibreglass window screen to fit the trays. If you don't have access to a dehydrator, you can use an oven set to a very low temperature (below 60°C) or try air drying in a well-ventilated area, avoiding direct sunlight.

Temperature

The ideal dehydration temperature depends on the type of mushroom and your desired outcome. For cubensis mushrooms, a low-temperature setting is crucial to preserving their potency. The recommended temperature range is between 43°C and 54°C (110°F and 130°F). At higher temperatures, the active compounds in the mushrooms can degrade, resulting in a loss of flavour and potency.

Drying Process

Arrange the mushrooms in a single layer on the drying trays, ensuring none of them are touching. Set your dehydrator to the recommended temperature range and let it run for 4 to 12 hours, depending on the size and thickness of the mushrooms. Check on your mushrooms periodically to avoid over-drying, which can make them brittle. They are ready when they snap under pressure. If using an oven, drying may take up to twice as long, and you should monitor closely to prevent scorching.

Storage

Once the mushrooms are fully dry, allow them to cool down before placing them in airtight containers or bags. Glass jars or plastic containers with tight-fitting lids are suitable options. Condition the mushrooms by filling the containers about two-thirds full and loosely covering them. Store them in a dry, well-ventilated place for 4 to 10 days, stirring or shaking the containers daily to separate pieces. Finally, transfer the conditioned mushrooms to moisture-proof containers or bags for long-term storage.

Frequently asked questions
