Here is an indoor aquaponics garden overflowing with watercress, lettuce, parsley and lemon balm -- all fertilized with the waste of just TWO gold fish!
The plants in the hydroponic grow bed, which is filled with hydroton and lava rock, filter the water before it returns to the fish in the reservoir.
What a great way to put your pets to work!
