    Hi guys,

    I`ve been working and picking up some delicious oystermushrooms. I was wondering what kind of mesaurments do you take to know that your cultivation is working in a efficient manner?

     

    Thank you

    Hi Diana,

    The main measure to begin with is just the yield of mushrooms per amount of substrate.

    For example, 2.5kg of mushrooms from 10kg of substrate would be a reaosnable yield as you would hope to grow at least 25% of the weight of the substrate in fresh mushrooms. This is just a rough  measure however as it depends on many factors, not least the moisture content of the substrate.

    So if you wanted to go a step deeper, then you would meaure biological efficiency, which is the weight of the fresh mushrooms in relation to the dry weight of substrate.

    For example, if:

    dry weight of substrate = 1kg

    fresh mushroom weight from 2 flushes = 900g

    Then your biological efficiency (BE) would be 90%. With Oysters it is possible to achieve more than 150% BE if everything is working optimally, but anything from 100% upwards is good.

    I guess it’s also worth calculating the amount of coffee grounds you’ve recycled as a success measure too!

    Best wishes,

    Adam
