hydro systems

i want to make a hydro system that can grow like 6 plants at a time. what the best system for me? also what exactly do i need to buy for it and how much would it cost?

DWC(deepwaterculture) i do a 10 gallon rubbermaid i use 6 gallons for 2 monsterous plants. if you are going for a MINI grow u can do this same setup with 6. if you do it this way you should SOG(seaofgreen)cut all lower branches and focus all growth to the top of the plant.or you can get a bigger res for more space and bigger plants.and heres some links that should help ya out.
