The deep flow technique (DFT) is one of the numerous hydroponic systems available, and it has a lot of advantages for producing small water-loving crops like lettuce!
You’ll learn about the advantages of deep flow technique hydroponic systems in this article, but first, let’s go over the basics of how it works.
To stimulate growth, some hydroponic systems actively provide nutrient water to the plant roots.
Other systems rely on the plant roots just being in the nutrient water indefinitely.
DFT hydroponic systems combine the best of both worlds.
Aerated nutrient water from a reservoir is pumped up to flood one side of a tray.
With the help of a floating board, the plants perch on top of the tray, their roots hanging within.
The water rotates as it is pushed in, supplying nutrients to the plants’ roots.
A drain, on the other hand, returns the used water to the reservoir.
Now we’ll look at the advantages of this system.
DFT Systems’ Advantages Reliable
You won’t have to be concerned about your plants in the event of a power loss or equipment failure.
If there is a problem with the water pump, DFT systems can hold enough water at one time to keep water in the trays.
This allows you to fix the problem while keeping your plants alive!
Maintains a constant temperature
The rafts, or floating planks, that keep the plants on the water’s surface are frequently insulated.
Furthermore, when there is a large volume of liquid compared to the container’s surface area, less heat is lost.
When compared to the surface area of the trays, there is a lot of water in a DFT system.
DFT systems are one of the most temperature stable hydroponic systems due to the insulation of the rafts and the volume to surface area ratio.
Vertical farming is simple.
Because of their weight or size, certain hydroponic systems aren’t suitable for vertical farming.
DFT systems, on the other hand, are just deep enough to hold enough water for the crops without becoming too heavy or tall.
This saves space and makes vertical farming easier by allowing the trays to be stacked on racks.
Water is pumped out of a reservoir, into the system, and then drained back into the reservoir in DFT systems.
A recirculating hydroponic system is what this is termed.
It uses substantially less water than systems that use fresh water every time since it can capture and reuse it.
Setup is simple.
Deep flow technique systems are simple to construct since they use common parts.
This makes them simple for newcomers or farmers looking for a low-cost system to get started with.
DFT systems clearly have a lot of advantages!
