Product Details

Description

This spectacular strain is fast and flat out the most productive Oyster we've tested. A wide range in fruiting temperatures and its aggressiveness make it a great choice for pasteurized substrates and acceptable for soaked and limed straw. For first several fruitings, clusters should be picked early and handled carefully, or quality may suffer. Densely clustered fragile caps require gentle handling. Spawn run time: 3 weeks. Fruiting temperature: 55-85°F.

Top quality spawn as usual! arrived on time and in good shape. Now I just need to find more fiber to feed to my cellulose eating beasties :D.
