The nutrient film technique (NFT) offers a number of advantages that make it popular with both commercial and home growers.
This method offers a lot of advantages when it comes to growing leafy greens!
We’ll go over the advantages of nutrient film technique hydroponic systems in this article, but first, let’s go over the foundations of how it works.
Crops are planted in small gaps on top of an enclosed tube in an NFT system.Pumps transport nutrient-rich water from a reservoir to the channels.Because the channels are angled, gravity pulls the water down the channel and through the roots of the plants.The water flows out once it reaches the other side of the channel.The water is then returned to the reservoir, ready to be used again.
Only a small amount of water is discharged at a time through the trays.Otherwise, the plants may drown or have their roots rot.Because only a small amount of water flows through the plant roots at a time, it resembles a film of nutrients rather than flowing water.
Let’s look at the advantages of nutrition film technology systems now.
Water is saved in NFT systems because only a small amount of water goes through the plant roots at a time.
Furthermore, because it is a recirculating system, the water pumped out of the reservoir is caught and reused.
It uses a lot less water than systems that utilise fresh water every time since it can collect and reuse it.
Vertical farming is simple.
Because of their weight or size, certain hydroponic systems aren’t suitable for vertical farming.
Fortunately, NFT systems are deep enough to hold plant roots and water while being thin enough to be easily expanded upward.
As a result, an NFT system makes it simple to save space and grow more per square foot.
Prevents the accumulation of salt
Because the majority of nutrition solutions contain salt-based minerals, any nutrients that the plants do not receive will be left behind and accumulate over time.
As the salt builds up, it might cause problems for your plants by interfering with the nutrient solution.
However, because NFT systems constantly circulate water, salt cannot build up in any one area for an extended period of time.
Utilizes fewer resources
To sustain the plant’s stem and roots, most hydroponic systems require the use of a growing media.
However, most NFT systems do not use a growth medium. So that’s one less thing you’ll have to spend money on to keep your hydroponic system running.
Plus, because the NFT system uses so little water at a time, you’ll use up your nutritional solution less quickly, saving you money!
