Magic Mushroom Spore Prints: Psilocybe Cubensis

A spore print is made by resting the cap of a mature mushroom on sterile foil so the spores drop out as a fine, dark purple-brown imprint. It is the driest, most concentrated way to keep spores, which is exactly why a print outlasts every other format on the shelf.

Why collectors choose spore prints

Two things set prints apart. First, longevity: kept cool, dark and dry, the spores stay viable for years, so a print is the natural way to archive a strain. Second, freedom: from one print you can make several of your own spore syringes or agar plates whenever you like. The trade-off is that a print is not ready to use straight away, you still have to scrape it into sterile solution first.

How the formats compare on shelf life

Spores come in a few forms, and each keeps for a different length of time.

Working with a spore print

For microscopy, scrape a little of the print onto a slide or into a drop of sterile water and view it under the scope. To make a syringe, suspend a scraping in sterile water and draw it up. Sterile technique matters throughout: work clean, ideally near a still-air box, since a single contaminant can ruin a sample. If you would rather skip straight to fruiting, a grow kit arrives fully colonised instead.

Our strains

We stock prints across proven Psilocybe cubensis genetics, from the forgiving Golden Teacher and the hardy B+ to the stronger McKennaii and exotic picks like Ban Hua Thai. Golden Teacher is the usual first choice, easy to recognise under the microscope. Each print is a single labelled strain, so you always know which genetics you hold.
