The 2011 manual asks for a minimum of 3 to 4 air changes per hour once fruiting starts. That is far less than a button room needs, but it is not zero, and a sealed room gives long stalks with small caps.
Hold 30 to 35 C. The folder keeps humidity at 80 to 90 percent; the manual's water management section narrows it to 80 to 85 percent during cropping.
