Starting a new hydro system....help!

Hey guys, i'm looking to build a new hydro system and am wanting to grow around 20 plants. I have only grown in a bubbleponics hydro kit before am thinking of just getting a huge tub and creating 20 plant sites on the top but am still not 100% sure. Any suggestions would be greatly appreciated, thanks guys.

It depends on how big the plants will end up.
Flood and drain system would probably be the easiest to build.
