I cannot explain how simply brilliant I think this is: http://katsmama.com/2011/04/30/inside-out-self-watering-pot/
I also cannot explain how very rarely I subscribe to anything via email, but this katsmama.com blogger just solved something so simply that has been so hard for me, that I've wasted so much time on, I'm so thrilled, I subscribed via email. Seriously. Wow. I can't wait to read the whole blog there!
