Blue Oyster (pleurotus ostreatus)
This is a Growers Block (GB), which means it does not come with a spray bottle and directions.
Weight: 5 pounds
Fruiting Temp: 60 – 65F
Humidity: 80 – 90%
When grown at cool temperatures, the caps will be darker than when grown above 65F.
Blue Oyster mushrooms grow best in humid conditions with ample fresh air exchange (FAE) to keep the carbon dioxide levels low (~700ppm). If mushrooms have long stems with small caps, they need more fresh air from outdoors where ambient CO2 levels are ~400ppm.
**Guaranteed to grow or your money back.**
We always use UnicornTM bags filled with hardwood sawdust and soy hull substrate hydrated to 58%, all 100% sourced and made in the USA.
They can be grown in a fruiting chamber with Oyster mushrooms and Lions Mane. Cooler temperatures and bright light help give them a deep rich blue color.
