Can I use sponge for hydroponics?

Hydroponics involves growing plants without soil. You can certainly use sponges to start seeds for hydroponics, but they will need a different medium to grow into full-fledged plants that you can get a good harvest from.

What is the point of aquaponics?

Aquaponics is a form of agriculture that combines raising fish in tanks (recirculating aquaculture) with soilless plant culture (hydroponics). In aquaponics, the nutrient-rich water from raising fish provides a natural fertilizer for the plants and the plants help to purify the water for the fish.
