Yup, 2 to 1 is what most people recommend, but as badflash says, 3 to 1 might give you a better edge. If you're planning on a 1 to 1, better plan on a biofilter as well.

BTW, Welcome to the forum ...... glad to have you here

I guess its back to the drawing boards as i try to work out how to squeeze more growing area into my limited space
