Roots over rock bonsai - aerial root growth

The tree was doing great until it got scale and lost all of its leaves. I was able to eradicate them and had to cut the branches back. Its doing very good again.

Next step was to get aerial roots to grow. I live in the Northeast USA,so I made a homemade green house. It works great, only 4 weeks later and I'm getting root growth in multiple places.
