Soil Mixture Ideas?

I am about to start mixing up some new soil for a new grow... I was wondering if anyone had any ideas on what ratios to use? I have neutral potting soil, perlite, and sphagenum moss... I was thinking of mixing them in equal parts... what do you guys do?


Thanks...

i have always done 2 part soil, 1 part perlite, 1 part vermiculite and it works well for me. never really used the moss though
