What’re the key benefits of using Nutrient Film Technique hydroponics? Well, did you know that NFT can grow plants up to 30% faster than traditional soil-based methods? 

This is because the roots of the plants are constantly exposed to water and nutrients, allowing them to absorb what they need quickly and efficiently. (1)

Additionally, since there’s no soil involved, there’s less risk of pests and diseases affecting your crops.

Another benefit of NFT hydroponics is that it allows for a more controlled environment for your plants.

With traditional gardening methods, factors such as weather and soil quality can greatly affect the growth of your crops.

However, with NFT hydroponics, you have greater control over variables such as temperature, pH levels, and nutrient concentrations.

This means that you can create an ideal growing environment for your specific crop needs.

Lastly, NFT hydroponic systems are highly efficient in their use of water and nutrients.

Because the system recirculates water through a closed loop system rather than watering plants from above like traditional methods do (which can result in excess runoff), less water is needed overall.

Additionally, since nutrients are delivered directly to the roots rather than being dispersed throughout soil or other mediums where they may not be fully absorbed by plants, less fertilizer is needed as well.

Ready to start growing with NFT hydroponics? The first step in choosing the right plants for your system is to consider which ones will thrive in this type of setup.
