Hydro/Aquaponics

I want to setup a very small indoor system to get a feel for this. I'd like to see how much plant matter I can grow from that. Probably just basil and oregano.

???

• How much can I grow?
• What grow medium
  • lava rocks
  • perlite
  • gravel
• Do I need a filter between the fish tank and the plants?

It looks like the ratio is the gallons of grow bed to gallons of tank it's somewhere around 2:1.

Components

• Fish tank : I have the old 10 gallon fish tank.
• Pump
• Beds
• bell siphon : simple to make from pvc
• auto feeder (for fish)
• Lights : I'd like to use LEDs because that's what I'll want to use in the long run.
• Timers
• secondary tank

The fish tank is the primary tank
