Yellow Umbo F7 Liquid Culture Syringe

The Yellow Umbo F7 Liquid Culture Syringe (Ps. ochraceocentrata x Ps. cubensis 'Jack Frost') is the first documented hybrid between Psilocybe cubensis and another Psilocybe species. This breakthrough was achieved by Yoshi, who mated monokaryons of Ps. cubensis and Ps. ochraceocentrata using serial stripe techniques and advanced microscopy methods developed with the help of Kilor Diamond. Each stage of the process was verified by microscopy and cross-species validation tests conducted by Imperial Labs. This project marks an important milestone in domestic mycology.

Psilocybe Cubensis Yellow Umbo stands out for its vibrant yellow hats and robust mycelial growth. Known for its rapid colonisation and reliable fruiting, this strain is a top choice for growers looking for a visually striking and highly productive mushroom. Its unique appearance and resilience have made Yellow Umbo a sought-after variety in the growing community.

Moreover, our 10ml PE7 liquid culture syringe is also manufactured under sterile conditions to ensure maximum purity and minimise contamination. PE7 is an excellent option for growers looking for a robust, potent strain with impressive yields and unique characteristics, offering consistent success in cultivation.

Main characteristics

• Strain: Psilocybe Cubensis Yellow Umbo - a rare and visually appealing strain with unique yellow caps.
• Volume: 10 ml sterile syringe with nutrient-rich liquid culture.
• Purity: Professionally isolated and prepared under sterile conditions to ensure consistent, reliable growth.

What you need to grow mushrooms

1. Grain (nutrition): Mushrooms need a source of nutrients to grow. Grain such as rye or maize is often used, as it is rich in carbohydrates and other nutrients essential for the growth of the mycelium (the root structure of the mushroom).
2. Substrate (soil): The substrate provides physical support for the mycelium and helps with water retention. This can be, for example, wood, straw, sawdust or any other organic material in which the mycelium can grow. The substrate should be sterile or well-treated to avoid unwanted bacteria and fungi.
3. Culture (the mycelium or spores): This is the biological basis of the mushroom. The mycelium is the vegetative form of the mushroom and grows through the substrate to form the mushroom. It can be bought as 'liquid culture' or home-grown from spores. (We recommend liquid culture)
4. You can grow mushrooms with these three components, depending on the kind you want to grow.

Humidity and hygiene

The process requires careful control of factors such as temperature, humidity and hygiene to achieve a successful harvest.

Humidity: You maintain humidity by growing mushrooms in a bag or monotub. This ensures the substrate stays moist, which is important for the mushrooms' growth.

Hygiene: To prevent contamination, we work with an injection port on the bags. This makes it easy to inject the mycelium (the "seeds" of the mushroom) into the bag without the need for a special clean room. Customers should only use a clean needle to ensure everything remains hygienic.
