I like the idea of a dip for the clones. When you look for neem oil, you might also look for an miteicidal dip (like pyrethrum) to further buffer them against attack. More Neem info at http://www.neemfoundation.org/index1.htm

You can create a hostile enviroment for the mites while treating for them. They do not like humidity or cool temps. You can also spray leaves with cool water periodically to keep them away when not treating with miticide.
