 rH Levels in Casings

Does anyone know what rH levels should be used with casings? Or does it depend on exactly what type of casing you should do? AFOAF read a FAQ on here saying that a 'Cool Mist Humidifier' would probably be too much humidity. He guesses that 70% rH would be too high in the terrrarium, since a casing holds in so much moisture.
My FOAF doesn't want to be misting the casings everday, he leads a busy life, and was looking to have it automated. Any ideas?

A coolmist isnt too much for casings. About 90-95% is ideal for casings. You can go a bit lower though and be okay. My foaf runs his cool mist 24/7.

Yes, here it is: Apprentice Casing Tek

3. Excessive Humidity
Generally, casings do not require as much humidity as cakes because it's the casing layer itself that creates the micro climate favorable to pinhead formation and development. As the mushrooms grow, they draw moisture from the casing layer as well as the atmosphere. That being said, the use of cool mist or ultrasonic humidifiers, or perlite humidification, may be too much for your casings.

OK.
This statement is not incorrect, it says that the use of ultrasonic humidifiers (NOT cool mist humidifiers) or perlite is an overkill.
Casings need a high(towards 95%-100%) humidity during the pre-pinning and pinning stage and 85%-90% after it, until cropping. These are the optimum conditions.
Keeping the humidity slightly above 90% throughout the cycle also works well.
Cakes on the other hand need a humidity of ~100% all the time, otherwise they will dry out and become bluish.

plus it's pretty easy to tell if your rh is too high (really fluffy growth)
