Those are just to name a few. I wouldn't recommend using topsoil unless your going to HEAVILY fill it with perlite and vermiculite. Also with the MG if you do use it be careful with the nutes/ferts as you can burn your kids easy with the time release shit in them. Lowe's has a soil there now called Jungle Growth which I'm currently using and so far so good. Only cost about $6 for a 2 cubic ft. bag (36lb.) which fills six 12in pots. That's been plenty for me so far. Transplanted 3 kids twice and I still have over half the bag left.

Basically though, almost any soil will work so long as you add the right soil mixes. That is the key to a good soil.
When you say HEAVILY how much are we talking here? Also what did you mix in with your Jungle Growth?
