About to start my new grow

This will be my first time trying to grow from seed to weed indoors, I have 1 fem roadrunner, 10 of the lowryder dwarf mix, and sill shortly have some Paradise magic bud fems, anywho, I'm going with soil, most likely ocean forest, I've read about mixing it with perlite, what's the best ratio of soil to perlite?
Thanx

You can do 60/40 ...soil/perlite

foxfarm soil is just fine the way it is. you don't need to add anything

Well, after doing some more reading, and talking to the guy at one of our local garden shops, who is also a medical grower, I decided to start my babies with Happy Frog soil, as it isn't as hot as OF. look for a grow journal to start shortly.
