I've never joined a CSS, but it's probably a great way to get some new plants. They look good.

I have to correct one thing, though. You don't have a gritty mix, but rather a peat-based mix amended with some grit. A gritty mix, as discussed in these forums, contains no fine material like peat or topsoil. It may sound nitpicky, but there's a big distinction in terms of how the soil functions.
