- The Wick System: a wick is used to extend from the reservoir of nutrient solution to the growing medium, and wicks the nutrients and water up to the roots of the plant for absorption.
- Aeroponics: a mister or nozzle head is used to mist or spray the nutrient solution onto the exposed roots of the plants.
- Nutrient Film Technique (NFT): plant roots are exposed below the growing medium, into a shallow cascading stream of nutrient solution that is being pumped up from the reservoir and is running through a tube below the medium.
- Ebb and Flow (Flood and Drain): the system is on a timer and will periodically flood the area that holds the plants in the growing medium with nutrient solution from a reservoir, and then drain back out again.
- Water Culture: the plants are in a growing medium, and float on top of the nutrient solution that is bubbling to provide oxygen to the submerged roots.
- Drip System: nutrient solutions drips into the growing media and trickles down past the plant’s roots.
