For that setup I would suggest ebb and gro. If you look around you can get a 12 pot system for under 400. Then 6 pot add on for about 60 bucks. You can expand to 48 pots on a 55 gallon rez. Only one rez to keep a check on and an over all consistant harvest. If you need the I can tell you where I found the cheapest. The cost can seem alittle high but will pay off well. Depending on where your at you will need a heater and maybe a chiller. Well worth it for easy operation.
We started with GH flora for years and then tried Technaflora recipe for success with very good results and alot less salt build up.
