I personally believe 600 is enough. I use 400 for about the same size grow. It does well, at the same time I am looking to get another 400 to increase buds and add another hydro system....But yes it is enough!

I don't have any pics but you leave the clone in the cube and soil the entire cube. Roots will grow through the cube. Taking the cube off will damage the roots.
