Oyster Mushroom <em>(Pleurotus Ostreatus)</em> variety G3


  • Medium/large sized fleshy mushroom (6–13cm).
  • Very dark coloured almost black, it gets darker with low temperatures.
  • Flat and excentric cap.
  • Very productive.

Growing Characteristics

  • Quick incubation and pinheading.
  • Easy pinheading under 14ºC.
  • High resistance to low temperatures.


  • Temperature should not be allowed to rise for long periods over 30ºC during the INCUBATION period.
  • Sudden temperature changes should be avoided during the incubation period to prevent condensation in the substrate.
  • Once the incubation period is ended, the temperature should be lowered slowly.
  • When pinheads start to be visible in the packs’ holes, ventilation intensity can be raised.
  • During the GROWING PERIOD, relative air humidity should be kept between 82 and 87%.
  • CO2 levels should be kept as low as possible, maintaining the rest of the parameters.
  • Fruiting bodies should be harvested once the mushroom’s edge is straight and before it starts to break.


It is a very versatile mushroom. Depending on the number of fruiting bodies a mushroom for unpackaged selling can be collected or for packaged selling, as it is very attractive on the stalls due to its shape.
