Nutrient film technique - Commercial hydroponics farm in India

 

NFT stands for Nutrient Film Technique.

In the world of Hydroponics, Nutrient Film Technique is quite popular. NFT is a method of growing plants in nutrient rich solution. What makes it stand out? Let’s look further,

 

What is Nutrient Film Technique?

Nutrient Film Technique  is one of the methods of growing plants in hydroponics where a narrow stream of nutrient rich oxygenated water is circulated where it  just touches the roots of the plants. NFT Channels are usually made out of plastic which are food grade in nature. Most of the commercial hydroponics farms in India employ this technique for successful crop production.

The nutrient solution flows in a very thin film of about 1-2mm in height, hence the name nutrient film technique. The continuous flowing of nutrient film is very essential to keep the nutrient solution oxygenated.

Types of Nutrient Film Technique

Broadly, commercial hydroponic farms in India, use two different type of systems. NFT and DFT. DFT stands for Deep Flow Technique. The only difference between these tow systems is that the depth of the solution is much higher in DFT. 

DFT rose to popularity due to its resilience to power outages which are common in rural areas.

The channels that are used for commercial NFT farms are of two types. 

Open type – The channel is made of two parts here. One is the top and the other is the bottom channel. The top channel acts like a lid and helps maintain the channel between crops. 

Closed Type – This channel is made of one piece. Maintenance and cleaning is done via the slots made for the netpots.

Jokes aside, NFT system is better suited for plants that have a shorter time to harvest. Green vegetables and salad crops are the best plants for growing in an NFT sytem.  In all the commercial hydroponics farm setup by Hyperfarms, we suggest the following crops for planting in an NFT system

 Lettuces,  Spinach, Kale, Bok Choi, Tatsoi, Coriander, Parsley, Basil, Chives etc. 

These crops have shown high yield in a short period of time when grown using NFT.

NFT System Components

Whether it is an Indoor Hydroponic NFT system or a commercial hydroponics NFT system, the components required to build a successful NFT is more or less the same.

 Let us have a look on what you need to build an NFT system:

  1. NFT Channels or gullies. 
  2. Pump for recirculation of nutrient solution.
  3. Net pots to contain the plants.
  4. Growing media to start seedlings
  5. A reservoir/tank to contain nutrient solution.
  6. Tubes to distribute the water from nutrient tank to NFT channels.
  7. Return system to carry the used nutrient water back to the nutrient tank.
  8. Filters/Controllers for larger commercial NFT installation
  9. Last but not the least, the nutrient solution that will help grow plants.

Now that we know the components of an NFT system, let us also know what the NFT system requires for successful operation. The main and important dependency of a NFT system is its need for continous power.  

 

Advantages of  Nutrient Film Technique

  1. NFT compared to other growing methods of hydroponics, helps in mass production of plants on a commercial scale.
  2. Uniformity of the produce across the farm. This is one of the main advantages of NFT.
  3. You can easily inspect the growing roots for any symptoms of diseases etc.
  4. Very minimal water used as the water is recycled. Upto 85% of water savings compared a conventional way of production.
  5. The nutrient solution is not drained to the ground, thereby avoiding ground water contamination.
  6. No Soil borne pests to the crop as there is no contact with soil.
  7. No problem of weeds. No weeding results in reduced manpower input.

 Disadvantages of Nutrient Film Technique

There is always 2 sides for a coin. Likewise, the diasadvantages of NFT system are:

  1. The major disadvantage is the need for continuous electricity. If the flow of nutrition stops, plants get stressed and dry out very quickly.
  2. Not suitable to grow long term plants and also crops whose roots are consumed. E.g Potato.
  3. Equipment failure, if unnoticed, can quickly results in crop loss.
  4. Infections can spread easily if not contained at the right time ( as with any system), since the reservoir is shared for all the plants.,
  5. Performs very well in colder weather conditions or a climate controlled greenhouse.
