I started my first Aerogarden (a Pro100) on November 1, 2007. Since then I've acquired two Aerogarden Mini3's (not the same as the newer Aerogarden3), Feb'08, and a Deluxe, Oct'08.
I also have outdoor gardens - sort of. I live in a very vertical townhouse, with only western exposure. There's a little ground, that's more-or-less constrained to be planted in ornamentals. And three decks and a driveway. So I do a lot of container gardening outside.
And I love to experiment.
