Are there any hydroponic gardeners out there?

Question:If so, is it an expensive garden to keep up? Can you grow more then just tomatoes. I am having problems getting basic info off the internet. Thanks.

Answers:
You can grow most anything but the expense is in the set up. Up keep isn't that expensive.It takes a lot time and attention than other methods. http://www.howtohydroponics.com/...
