I couldn't tell you the best humidity levels James obviously the lower the better a good indicator is to keep a small amount of micro balloons in an open container on a shelf in your workshop(be wary of it though as its not good to inhale),if the microballoons are clumping together its too humid to mold but if they are light and airy after a stir (kind of like talcum powder) then your good to go.some of the boys over here who live in colder parts have de humidifiers in their workshops for when they paint maybe one of these would work for molding too?

With humidity aim for 50 % or lower , with any of the resins as they dry they generate heat which draws moisture out of the air , and when they dry it will not be as strong because of the moisture in the resin .

James, also dont know the exact humidity level to avoid but my understanding is that is it not one particular humidity event which ruins the casting it is the amount of moisture which the resin and the microballoons have absorbed.

Microballons are easy to tell if they have absorbed too much, as chris said, if they are soft and easy to stir like talcum powder then they should be good. If they are not it is easy to fix, just spread them on some baking paper and put them in a low oven for an hour. I have done this a couple times with mine and works a treat.

Resin is heaps harder to detect other than the final foaming effect. Once it starts to ruin I dont think you can do anything about it. Then have a maximum shelf life of 6 months generally cause they start absorbing the moisture quick. What I do it minimise exposure of the resin to air and when storing spray in some air blanket which helps.
