Yellow Umbo “F7” – Liquid Culture Syringe

Description

This Yellow Umbo liquid culture comes in a sterile 10ml syringe. Use it to inoculate grain spawn or an All In One grow bag.

Yellow Umbo (Ps ochraceocentrata x Ps cubensis ‘Jack Frost’) is the first documented hybrid of Psilocybe Cubensis with another species! Yoshi achieved this by pairing monokaryons of Ps cubensis and Ps ochraceocentrata. Serial streaking and new microscopy techniques, created together with Kilor Diamond, made this possible.

Microscopy confirmed each step of the process. In addition, Imperial Labs ran interspecific verification tests. This project is a momentous achievement in home mycology.

The Psilocybe Cubensis Yellow Umbo is an exceptional variety distinguished by its bright yellow caps and strong mycelial growth. Growers value this strain for its rapid colonization and reliable fruiting, making it an excellent choice for cultivators seeking a potent and visually striking mushroom. Its unique appearance combined with its resilience has made Yellow Umbo a highly desirable strain in the cultivation community.

We prepare our 10ml Yellow Umbo liquid culture syringe under sterile conditions to ensure purity and minimize contamination risks. Whether you’re a beginner or an experienced grower, this culture provides a dependable foundation for achieving a high-quality harvest.

Yellow Umbo’s distinctive color and potency make it an excellent addition to any cultivation project.

How to Use Yellow Umbo Liquid Culture

Yellow Umbo is a hybrid with bright yellow caps, rapid colonization and reliable fruiting. In addition, a liquid culture skips the slow germination stage of spores. As a result, the mycelium starts to colonize almost right after you inoculate.

First, wipe the injection port with the alcohol wipe. Next, attach the sterile needle and shake the syringe gently. Then inject 1–2 ml per jar or 5–10 ml per bag of sterilized grain. Alternatively, inject straight into an All In One grow bag.

Finally, store any leftover culture in the fridge at 2–8°C and use it within 6 months. Want to know why growers prefer this method? Read our guide on spore syringes vs liquid culture, or read more about Psilocybe cubensis on Wikipedia.
