To be specific, while colonizing you want very little air exchange resulting in high levels of CO2 - up to 10,000 ppm with some species but 5k is great. Mycelium requires oxygen but the point is that high level of CO2. One of the most important fruiting triggers has nothing to do with spraying but has to do with reduced levels of CO2. As far as temp is concerned, your particular brand will grow at any temperature above freezing and thermal death is well over 90 degrees, do don't worry so much about temp.
