Answer 1

You literally have a world of information at your fingertips since you have access to the internet. All you have to do is do a web search for the information you need. A Yahoo search for "hydroponics" (include the quotation marks in the Yahoo search box) yields 2,790,000 results. If you do the same search, and are willing to spend a little time exploring, I'm sure that you will quickly find the information you seek.

Good luck with your search.
