Grommet looking for help

Hello. I have done a few surfing lessons but so far we've only ridden the whitewater. I reckon I'm capable of catching a green wave and I've caught some half-broken ones. About how far out do I need to go to get a green wave? Also, I have done some basic turning when riding whitewater waves, is a bottom turn the same thing or do I need to apply any other principles?
Thanks!
I appreciate your help.

Thanks!
