FAQs
Why is the difference between the large and small holes on the monotub?
Both the large and small holes are for gas exchange. However, given the proximity of the small holes to the substrate, many growers will remove the micropore tape during fruiting to increase oxygen — especially if the mushroom caps are too small and/or the stems are too thin and stringy. That said, if the mushrooms are growing just fine, many will just leave the micropore tape on (as it protects against contamination.)
Do I need to use micropore tape on the small holes, or can I just leave them open?
During colonization, you don’t want the small holes open. Covering them with the black micropore tape keeps out contaminants and maintains a higher CO2 level.
