But tomatoes? Yes! An indoor tomato crop is indeed possible using hydroponic techniques. Hydroponics is the technical term for growing plants in water with a soilless medium such as clay pebbles.

You can also use regular soil, a foam medium called Oasis, clay pebbles, products made from the husks of coconuts, or crumpled coffee filters in plastic plant pots.

Learning how to grow hydroponic basil indoors couldn't be simpler and enables you to cultivate delicious, aromatic herbs in every season without soil.

Every 15 minutes, water combined with waste from the fish tank is pumped up into a grow bed filled with clay pebbles. The poop-filled water feeds the plants.
