LEGUA CARDENAS, José Antonio et al. Optimization of nutrient film thickness of the NFT hydroponic system on radish yield. Rev. Inv. Cs. Agro. y Vet. [online]. 2025, vol.9, n.27, pp.214-224.  Epub 10-Set-2025. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v9i27.408.

Greenhouse hydroponics represents a key and sustainable alternative within organic agriculture, as it contributes significantly to water conservation and promotes the production of healthy vegetables. In this context, the Nutrient Film Technique (NFT) stands out as a hydroponic system designed to optimize water and nutrient consumption, consolidating itself as a valuable tool for sustainable agriculture and healthy food production. Nutrient supply in NFT hydroponic systems seeks to simplify management for farmers to keep nutrient amounts adjusted to plant needs, promoting a rational use of resources. Although Nutrient Film Technique (NFT) systems vary in size, complexity and composition, they offer an excellent avenue to grow crops in a sustainable and environmentally friendly manner. To validate this, a study used 12 PVC tubes, assigning three tubes to each level of nutrient solution film thickness. Seven seedlings were transplanted into each tube, resulting in a total of 84 seedlings in the hydroponic module. It was observed that crops harvested in the pyramidal hydroponic module, under greenhouse conditions, exhibited superior physical characteristics, including height, fruit weight and root development, specifically in the P4 group. Foliar analysis confirmed a positive trend in macro and micronutrient levels in the P3 and P4 trials, indicating that the ideal thickness of the nutrient solution sheet is between the ranges evaluated in these trials. Consequently, greenhouse hydroponics represents an efficient production method that conserves water, dispenses with soil and eliminates the use of pesticides.
