I created a Squidoo lens on hydroculture. Its purpose is to provide an
overview to the topic and offer some resources and experience. Check it
out at:

If you are not a Squidoo member, please join. It only takes a minute
and then you can rate lenses, leave guestbook blurbs, and even create
your own lenses. www.squidoo.com
