Yellow Umbo Cloud920® Ready-to-grow bag

The Yellow Umbo 2000cc premium magic mushroom kit offers an efficient cultivation method in which the mushrooms are grown directly in a grow bag. This method reduces the risk of contamination and simplifies the cultivation process. The Yellow Umbo Grow Bag has been specifically developed to produce a high yield under ideal circumstances. Discover this unique hybrid and experience a new dimension in home cultivation.

• Higher yields thanks to isolated culture
• Faster colonisation than regular strains
• Unique yellow appearance that enriches your collection

Origin of the Yellow Umbo

Yoshi Amano has made mycological history by creating the first documented cross between two different Psilocybe species. His Yellow Umbo, a hybrid between Psilocybe cubensis ‘Jack Frost’ and what was previously known as P. natalensis (now Psilocybe ochraceocentrata), represents a breakthrough in magic mushroom cultivation.

Yoshi worked closely with Kilor Diamond on this groundbreaking project. Together, they developed new techniques necessary to make this challenging hybridisation possible. We are honoured to now offer this strain in a Cloud920® Ready-2-Grow Bag.

The Unique Experience of Yellow Umbo

Yellow Umbo offers a special psychedelic experience that clearly distinguishes itself from cubensis mushrooms. Users describe a remarkably clear mental state during the trip, allowing you to think and communicate more clearly than with traditional species.

What makes this hybrid truly special is the combination of intense visual effects with minimal physical strain. You experience vivid visual patterns without the heaviness or discomfort that sometimes occurs with other species. Some even compare it to a ‘hippie flip’ (mushrooms + MDMA), but completely natural from one mushroom.

The trip comes on more gradually, which causes less anxiety during the initial phase. This makes Yellow Umbo more accessible, although the higher potency means that you need less than with standard cubensis species.

Many users appreciate Yellow Umbo for its therapeutic qualities, which it seems to have inherited from its P. ochraceocentrata parent. They describe the experience as ‘more therapeutic and healing’, ‘super euphoric and spiritual’ and ‘friendlier than cubes’. These characteristics make it a valuable addition for both recreational users and people who use mushrooms for personal growth and introspection.

Contents

1x Grow bag – Contains substrate with active mycelium (the cake). The bag has micro filters to keep out contamination and let fresh air in.
1x Large bag clip – Easy to use and a safer way to close your grow bag.
1x Elastic band – To tie around the top of the substrate to help prevent growth on the sides.

How to store this Yellow Umbo mushroom grow kit correctly

It is recommended to start the cultivation process as soon as you receive the grow kit. If you decide to start growing later, which can affect the quality of the box, you can store the grow kit in the refrigerator for up to 2 weeks (2°C to 8°C). You can leave the grow bag with mycelium in the box and place it in the refrigerator. Make sure your refrigerator is clean and free of mould. You can place it in a clean plastic bag as an extra precaution.
