How quality spawn and sterilization affects mushroom production. For an introduction to oyster mushroom growing, try our Rookie ‘roomer kit – ideal for first time growers who don’t want to spend a fortune on experimenting.
These three mushroom bags were all made on the same day…Image A:Old, poor quality spawn on unsterilized substrate. Spawn cannot colonize the substrate. Image B: Fresh good quality spawn on unsterilized substrate, results show mycellium colonizing the substrate, but VERY slowly. Image C: Good quality spawn on well sterilized substrate showing full colonization and early signs of fruiting – This is what you want!
