If you want to buy our flow hood Z-Strain mushroom spore swabs, be cautious as Z-Strain spores are “active spores” which are for microscopy or artistic purposes. We will not complete your order if you contact us regarding the cultivation of active spores. Similarly, for legal reasons if you mention cultivating active spores or ask for cultivating advice, you will be subsequently banned from the site.

These spores are from a species that produces psilocybin and psilocin. For legal reasons they can only ship to 47 out of the 50 United States. Shipping is unavailable to California, Idaho, and Georgia.

Spore Visibility Disclaimer: When you buy Z-Strain spore swabs, visibility is dependent on the characteristics of the spores themselves. As a result, not all spore swabs will look the same visually. All swabs are unique and may not look identical to each other or the picture above. Despite these visible differences, spore swabs are still viable for microscopy research.

Z-Strain Spore Information

Z-Strain has quickly become one of the best commercially available varieties for any skill level and is highly sought after. To start, people found the first specimen of this variety growing on a pile of dung on one of the Hawaiian islands. From there, researchers took the specimen to a lab and they began working on isolating its genetics. This extremely popular strain is the result of their hard work. This is an excellent addition to anyone’s spore library.

Mycologist have been admiring the Z-Strain cubensis for some time now. The shape and color of the caps make many people think that they are “Golden Teachers.” But, this could not be any more incorrect. Z-Strain is very much its own unique individual. They have also been know to grow very dense and tall towering over other mushrooms. Because of this, studying them is that much more interesting as people like to see what makes Z-Strain so different. In conclusion, Z-Strain is a must have for any collector.
