Deep Water
Culture Systems
Deep water culture hydroponics are simply plants suspended in aerated water. Deep water culture systems, also known as a DWC system, are one of the easiest methods of hydroponics on the market. A DWC system dangles net pots holding plants over a deep reservoir of oxygen-rich nutrient solution. The plant’s roots are submerged in the solution, providing it with perpetual access to nutrition, water, and oxygen.
Nutrient Film
Technique Systems
Nutrient film technique (NFT) systems suspend plants above a stream of continuously flowing nutrient solution that washes over the ends of the plant’s root systems. NFT is the most widely used hydroponics technique for commercial hydroponics. The channels holding the plants are tilted, allowing water to run down the length of the grow tray before draining into the reservoir below. A submersible pump then pumps the nutrient-rich water out of the reservoir and back to the top of the channel.
Dutch Bucket
Grow System
A Dutch bucket, or Bato bucket, is a hydroponic system in which two or more growing containers are connected to the same irrigation and drainage lines. This is an incredibly water- and nutrient-efficient method, ideal for growing heavy-feeding and vining plants like tomatoes, peppers, and eggplants.

Aeroponic
System
Aeroponics systems suspend plants in the air and expose the naked roots to a nutrient-filled mist. Aeroponics systems are enclosed frameworks, like cubes or towers, that can hold a multitude of plants at once. Water and nutrients are stored in a reservoir, and then pumped to a nozzle that atomizes the solution and distributes it as a fine mist. Aeroponics systems use less water than any other form of hydroponics.
