Oyster Mushrooms

Biological Efficiency

Is defined as the weight of wet mushroom to the weight of dry substrate. Biological efficiencies from 50-200% are possible. For wheat straw fermentation, the queestion would be what additive would provide the higher yields.

Hi Marcin, Attached is the word doc - [1] . No pics right yet but there is info and pics on the links i provide in the doc. Let me know if you have clarifying questions for the text. I will get to plugging some of this into the spreadsheet as well.

Yes, 1 pound per day is possible per tower. This would translate to one bucket fruiting per day. A bucket may do 1-2 (2-3?) pounds on its first flush so if the grower was rotating out buckets on a schedule, they could be constantly replacing a bucket that has finished fruiting with a new one. this translates to a lot of work. Most farmers work in pulses. For the home scale producer, mushrooms can be dried and stored quite easily. They will also store in the fridge for a week or more. Yield also depends on the amount of grains used and species/cultivar. Lots of variables so its tricky to make exact promises. But an average of 1 pound per day is doable if the grower has a good rhythm.

Cheers, Peter
