Here I would love to share with you our travels and adventures as international mushroom consultants. MEMOIRS about husband Pieter Vedder, who was a SCIENTIFIC PIONEER in Commercial Mushroom Cultivation Education. His practical handbook is in 9 languages and is called the MUSHROOM BIBLE: https://mariettesbacktobasics.blogspot.com/2020/08/modern-mushroom-growing-2020-harvesting.html

Over 1st Half of 1974 Our Mushroom Growing Training Centre Yielded 63% First Quality

In relation to my previous post: Our Dutch Mushroom Growing Training Centre Yielded YEAR ROUND TOP QUALITY MUSHROOMS! 

This photo shows the facts:

Classes taught by husband Pieter in German
12 growing rooms of 150 m²
12 week schedule
1973 yielded 52 crops x 20.4 kg/m2 with 60% 1st quality; 20% 2nd and 20% 3rd.
1974 1st half 18.6 kg/m2 yielded 63% 1st quality at 2.56 Dutch Guilder average market value.
~
The mushroom industry changed a lot over the last decades.
As a result of better composting techniques, supplementing, climate control and more productive strains, yields of 25–30 kg/m² in two or three breaks are quite normal.
With the introduction of the bunker–tunnel technique, the 12–week schedule inside the growing rooms has been shortened drastically, thus adding a lot to the production!
Of course all that is being mentioned in great detail inside our new book: modern mushroom growing 2020 harvesting | available WORLD WIDE at 40,000+ booksellers as print on demand

  3. Hello Mariette, I wonder whether the nature of top-grade mushrooms has changed over the years--i.e., their texture, taste, or cooking qualities. You have talked mostly about growing and harvesting techniques, but I further wonder if mushroom breeding has had advances, or anything that would change the nature of the mushrooms internally.

    1. Dearest Jim,
      No, the first quality or top–grade as you mention, still has the same requirement of having to be clean, firm and closed. If a mushroom starts deteriorating, having been left too long on the bed, or with poor handling post harvesting, they are no longer firm but become mushy and even smelly. That, of course affects their taste and cooking qualities.
      Spawn makers, world wide, have constantly improved the mushrooms for being less sensitive to certain diseases and for turning out near perfect; provided they get grown under the optimum conditions and on an optimum substrate with enough nutrients for doing so. Those growing techniques and harvesting affect the quality most.
      A full grown, healthy open mushroom, producing already spores seems to have some more flavor. Those are the so-called breakfast mushrooms in the UK, South Africa and Australia.
      Hugs,
      Mariette

  4. Who would have thought so much science and research goes into the growing of quality mushrooms? By the way, I love mushrooms any time and any place!
    Blessings, Mariette!

    1. Dearest Martha Jane,
      Indeed, for growing a profitable yield of good quality mushrooms, it is quite an intricate art to master!
      Funny enough, we just had mushroom risotto with dried Porcini added too. Love that...
      Always snatch up some good quality ones at Costco: https://mariettesbacktobasics.blogspot.com/2013/04/what-you-should-look-for-when-buying.html

  5. It's a much more complex growing system than I imagined Mariette. We have no idea when we pick up our mushrooms in the market 😊

      Well, it makes the consumer more aware of what all goes into it for being able to offer them for sale! In my comment to Martha Jane you can read from an earlier post what to look for...

    1. Querida Antónia,
      Sólo ha habido un centro práctico de entrenamiento de setas y mi Pieter lo fundó y lo dirigió como un excelente maestro durante dos décadas. Orgulloso de él y de nuestros excelentes resultados de calidad dentro de nuestra granja de instrucción. Todavía muchos pueden aprender de él, de nuestro libro...
      Abrazos,
      Mariette
