The Z-Strain is one of the best commercially available strains today, for any skill level. This strain is one of the most aggressive producers, as observed in the wild. The mushrooms are dense, meaty, and large.

All swabs are made and packed by MycoGen Tampa and were collected in sterile conditions in front of a HEPA certified filter flowhood. However, spores are exposed to air as soon as the veil breaks from the cap. We recommend testing on agar for viability. Per our policy, for ANY replacements, you have 10 days from the day of delivery to contact us, with photos of a contaminated agar test, otherwise replacement(s) will not be granted. Only tests on agar will be accepted for replacement.
