King Blue Oyster Premium LC

$15.00

Pleurotus ostreatus var. columbinus x Hypsizygus ulmarius

King Blue’s are not actually a Pleurotus eryngii, but a cross of Blue Oyster and Elm Oyster. This has quickly become a go-to culture for commercial growers, for its impressive yield and simplicity to grow. You can’t get much better than this for a high production variety. Extremely resistant to contam, a huge range of temperature tolerances, it’s hard not to grow huge flushes with this premium culture.

*Liquid cultures come with a sterile needle tip and contain 10ml of inoculant. All cultures are tested on agar and guaranteed to be contaminant free. Air bubbles in syringe are purposeful as we recommend shaking your syringe well before introducing to your choice of medium*
