The Yellow Umbo F7 Liquid Culture Syringe brings to life a unique hybrid: a blend of Psilocybe cubensis and Ps. ochraceocentrata. Developed by Yoshi in collaboration with Kilor Diamond and validated by Imperial Labs, this hybrid is a standout in the world of mushroom cultivation. With its bright yellow caps and vigorous growth, this species is a real eye-catcher in any growing setup.

Yellow Umbo stands out for its firm mycelium, rapid colonization and reliable harvest. The combination of beauty and power makes this strain ideal for growers looking to add something special to their collection. The visual flair and consistency in growth make for an enjoyable growing experience, time after time.

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

Key features

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

What do you need to grow mushrooms

1. Grain (nutrition): Mushrooms need a source of nutrients to grow. Often grain such as rye or corn is used because 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 aids in water retention. This may include 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 purchased as “liquid culture” or home-grown from spores. (we recommend liquid culture)
4. With these three components, you can grow mushrooms, 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 obtain a successful harvest.

Humidity: You maintain humidity by growing mushrooms in a bag or monotub. This keeps the substrate moist, which is important for mushroom 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. Clients should only use a clean needle to ensure that everything remains hygienic.
