culture to a full fruiting block — bundled together

My first ever grow and the Blue Oyster kit flushed in 9 days. Watching it double overnight was unreal. Already ordered two more.

The liquid culture was clean and vigorous — colonized my grain bags faster than anything I've bought online. This is my new go-to lab.
Austin, TX
Packaging was beautiful and it arrived perfectly. You can tell these folks actually care about the craft. The Lion's Mane was incredible sautéed.
