I've cloned without misting. The unrooted stem will uptake water, just like cut flowers will. The water uptake from the stem is enough to support the clone until it creates a root. I did this by having the clone sitting in water until it rooted.

Obviously misting is ideal. The point im making is that its not an absolute necessity.
