Note that what is sold as Ginseng Ficus has not much to do with growing bonsi. Treat it as any other houseplant.
IF you are really getting into bonsai growin, and you are working on a pine that you would like to turn into bonsai, you have loads of alternative options for soil. I won't get into specific brands because most likely you have different brands in your stores.
True bonsai soil has to be able to absorp water and give it off, yet be coarse so that any water not absorbed by the soil particles, drains freely. I am using a combination of baked clay (Originally intended for cats) and a sort of fake lava (Originally intended as building material: Floor filler).
Just look for coars material (1-5mm dimeter) that absorps water, is stable in frost and can absorp water. Ideally, it is light-weight for obvious reasons.
