Deep Flow Technique (DFT)

Definition - What does Deep Flow Technique (DFT) mean?

Deep flow technique is a type of hydroponic gardening where plants are planted in shallow beds, and a nutrient solution is constantly flowed over and around the root zones of the plants. The system is ideal for plants without deep root systems, and plants that have quick grow cycles.

As the nutrient solution flows away from the plant roots for short periods of time, deep flow technique is more suitable for plants that tolerate or benefit from slightly drying out between waterings.

Deep flow technique is commonly used in aquatic crops to ensure that aquatic crops receive the adequate nutrients. Often used in flooded, wet, warm environments, the deep flow technique has been shown to be particularly beneficial to watercress, rice, and water chestnut plants. This technique is also used in regions where it is impossible or difficult to grow fresh and leafy vegetables.

Deep flow technique allows planters to grow plants without soil. This technique relies mainly on aerated and fertilized water, which ensures that the plants receive proper oxygen and nutrition. Deep flow techniques also aids in maintaining the adequate temperature for the plants to thrive in and develop. In some cases, PVC pipe tubes are used to build this system.

In a deep flow technique system, most growers choose to go for around 2-3 inches of nutrient solution, which they circulate around the plant’s roots using either a pump or gravitational pull.

Delicate herbs like basil and cilantro are commonly grown using deep flow technique since this method has been shown to be particularly handy in distributing essential nutrients such as calcium and potassium.

The deep flow technique of hydroponics is a variation of the ebb and flow system, as well as deep water culture. In deep water culture, the plant roots are constantly submerged in the nutrient solution. The solution never flowers away from the roots.
