Main advantages of NFT systems
1. Greatly reduce the consumption of water and nutrient solution.
2. Eliminates substrate related supply, handling and cost issues.
3. Relatively easy to sanitize roots and devices compared to other system types.
4. Since no substrate is used, it is easy to check the roots for signs of disease, adequate nutrition, etc.
5. Regular supply of nutrients (and related flushing) can prevent the accumulation of local inorganic salts in the root zone, and maintain the pH and EC of the root zone unchanged.
6. Environmentally friendly, reducing sewage pollution.
