I see alot of people talking about hydroponics and alot of people use it so I want to try it out. I want to just do something small just to see how it goes. maybe a tub to fit about 3-4 pepper plants. I think im going to get my components such as Air pump, hose, air stone, and neoprene collars from this site http://www.4hydroponics.com/hydroponics/pumps.asp. I can get a tub from a local store. But whats the advantages of using net pots or neoprene collars? What kind of nutrients should I use in the water? Any advice would be great
