A 5-pack is the simplest way to start a comparison: five different strains, one slide set each. A typical first set pairs two classic references (Golden Teacher and B+) with three Penis Envy family strains, so you can compare spore size, shape and colour between a heavy-spored strain and the PE family’s sparser deposits.
How to order
Choose 5 different spore syringes from the list below and write your choices in the order notes at checkout. If you don’t pick, you’ll receive a house selection. Every syringe is 10cc of sterile water with spores scraped from a spore print, prepared in our Ottawa lab under 99.99% HEPA-filtered laminar flow, for microscopy and taxonomy research only.

Working through a 5-strain set
Label each slide with the strain and date, resuspend each syringe before use, and measure at least 20 spores per strain with a calibrated reticle (How to use a spore syringe). Keep the syringes you aren’t using sealed in the main part of the fridge (storage guide).





I would like to thank Spores WW for their service. My inoculated jars are looking dope and the mycelium look alive and kicking. They also sent me a surprise pack of syringes, which I found yesterday, I greatly appreciate that. Im going to turn my studio into a mushfarm now. Much love you guys.
