Since our hobby is an ongoing experiment for most of us, I experimented with a couple different things this grow. As I've said I have bent and tied my girls to shower curtain rods to expose the buds along the stems to more light, it's working great. I also used hydroton on top of my soil. I know it's generally meant for hydro grows but I read where in soil grows, the roots generally don't grow into the top two inches of the soil because it drys out too much and too often. Using hydroton on top of your soil keeps the soil moist enough that the plant will grow roots almost to the top of the container they are in, it works. So essentially you are gaining another couple inches of your soil instead of it being fallow with no roots in it. Try it, you'll like it.
