Welcome. You came to the right place. Although we have systems that grow mushrooms but do know why.
It may take a while but someone will come along and help. Mainly we have experience will moisture control in greenhouse to grow thinks. What is the ideal condition to grow mushrooms without destroying the building?
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
