what's your elevation?
folks forget that the boiling point of water, and therefore the cook times necessary
to achieve true sterilization, are different at higher elevation. i moved from sea level
to 6000 feet, and had to extend PC times from 3 to 4.5 hours (for 4x 5lb protein
supplemented substrates) to compensate. for my low pressure steam sterilization,
cook temperatures dropped from 210 to 200 degrees and i had to extend from 14
hours at temperature to 24 hours at temperature.
@Tstat if you're on facebook, check out the group "mycology classifieds"
your humidity is low or your air flow rate needs to be tinkered with. mushrooms require
evaporation to pin, so a fluctuation from 75-85% actually helps them pin more vigorously.
yours are pinning on the sides because there's a more humid micro-climate in that area.
sorry to say it, but to me, both brf and compost yields are garbage. i did supplemented
mycobags before retiring from cube growing, and pulled 5-6 dry oz per bag. i used coir,
horse poo, beet pulp, strawnet, and bran for my substrate. cubes LOVE beet pulp, but it
requires pressure sterilization and careful inoculation.
here's a picture from our farm, just so you can see i'm qualified when i give you advice.
these are pholiota adiposa, the chestnut mushroom. we run 4-500 blocks of edibles at
a time, i am to the point where i mak e more money with edibles than i ever could with cubes.
