Nutrient Film Technique – Welcome to Useful Insight 2023, where we explore the latest and most effective techniques in agriculture and horticulture.
In this blog, we will be delving into the Nutrient Film Technique, a hydroponic system that has gained popularity in recent years due to its efficiency and versatility. With a focus on providing the necessary nutrients to plants in a controlled environment, the Nutrient Film Technique allows for optimal growth and yield, making it an attractive option for both commercial and personal use. Join us as we take a closer look at this innovative technique and discover how it can revolutionize the way we approach farming and gardening.
You might wonder nutrient film technique. Here is the explanation.
Nutrient Film Technique
Techniques for creating nutrient films
The roots of plants grown using the nutrient film method (NFT) are dangled above a constant flow of nutrient solution. The grow tray’s channels are slanted so water may run down the length of the tray and into a reservoir below. After that, an air stone is used to oxygenate the water in the reservoir. Nutrient-rich water is pumped out of the reservoir and up the channel by a submersible pump. The nutrient film method is a type of hydroponics in which the water is recycled.
The plant roots in an NFT system are not submerged in water, as they would be in a deep water culture hydroponics setup. On the contrary, the stream (or “film”) only runs over the tips of their roots. The plant’s exposed root system will absorb the water through its tips while receiving plenty of oxygen. The shallow film may easily slide over the root tips thanks to the grooved bottoms of the channels. Also, this stops water from collecting around the plants’ bases and causing problems.
Although water is continually being recycled in nutritional film method systems, it is nevertheless recommended to drain the reservoir and restock the nutrient solution once per week or so. This will guarantee that your plants receive a enough amount of food. A gentle incline is required for NFT channels. There won’t be enough time for the water to slow down and nourish the plants if the canal is too steep. Oversaturation can occur if the channel is being overloaded with water, which can lead to plant death.
As Nutrient Film Technique hydroponics can sustain several plants in a single channel and are simple to mass produce, they are in high demand in the commercial sector. Light plants like mustard greens, kale, lettuce, spinach, and even fruits like strawberries are ideal for nutrient film technology systems. Trellises are needed to support the weight of heavier fruiting plants like tomatoes and cucumbers.
The benefits of a system based on the nutrition film technology are discussed.
Using little energy: Due to the fact that NFT hydroponics recycle the water, they do not need copious amounts of either water or fertilizers to thrive. Maintaining a steady flow also hinders salt buildup on plant roots. Furthermore, nutrient film method systems don’t need growth media, so you won’t have to buy any or deal with the inconvenience of always needing to replace it.
Due to its modular architecture, systems based on the nutrient film technology are ideal for industrial and commercial applications. It’s simple to add more channels when you’ve already got one up and running. Your greenhouse may be packed to capacity with a wide variety of plant channels. Having an individual reservoir for each channel is recommended. In this way, you can keep your business afloat in the event of a catastrophic event, such as a pump breakdown or the outbreak of a waterborne illness.
To what extent do the drawbacks of the nutrition film technology system manifest themselves?
Inoperative pump: It is possible for your plants to dry up if the pump stops working and the nutrient film stops being circulated in the channel. Without water, your entire harvest might expire in a matter of hours. Constant monitoring is required while tending to an Nutrient Film Technique hydroponic system. If you want your pump to work well, you need to keep a close eye on it.
When plants are too closely spaced or when root development is excessive, the channel might get plugged. Your plants will perish if water cannot reach them because their roots are clogging up the passage. The plants growing at the bottom of the canal are a perfect example of this. If the plants at the very end of the channel are consistently underperforming in comparison to the remainder of the channel, you may want to reduce their number or replace them with a smaller unit.
