If you are trying to intercross seeds to get "X" seed and "X" seed comes from plant "A" when mixed with plants "B" and "C", would it matter if you used Thanalan Topsoil for plants "B" and "C"? Or could you get seed "X" from plant "B" and "C" anyway?

I hope that's a clear example for what I'm trying to ask.


Edit: I just realized there's a gardening forum, oops.
