Oh, one minor thing: I saw you had some electrical cables and such on the BOTTOM of your closet. I'm sure I'm more paranoid than most people about fires (since my home burned down last year), but...that seems a little scary, especially in conjunction with hydro. Electrical stuff on the bottom + gravity + hydro + pump problem or something = potential fire hazard. If my saying something about it helps prevent someone ELSE from watching their home burn down, well, I'd just feel guilty if I didn't say something. Doesn't hurt to be a little extra careful when it's your life at stake.
