RT Journal Article T1 Expanding the Level of Technological Readiness for a Low-Cost Vertical Hydroponic System A1 Borrero Sánchez, Juan Diego AB Climate and social changes are deeply affecting current agro-food systems. Unsustainableagricultural practices and the low profitability of small farmers are challenging the agriculturaldevelopment of rural areas. This study aims to develop a novel, modular and low-cost verticalhydroponic farm system through reviews of the patented literature, research literature and variantsof commercial products. After a detailed conceptualization process, a prototype was fabricated andtested at my university to validate its technology readiness level (TRL). The outcomes supportedthe usability and performance of the present utility model but highlighted several changes that arenecessary before it can pass to the next TRL. This study shows that the prototype has the potentialto not only solve food sovereignty but also to benefit society by advancing the innovations in foodproduction and improving quality of life PB MDPI SN 2411-5134 (electrónico YR 2021 FD 2021-10 LK http://hdl.handle.net/10272/21005 UL http://hdl.handle.net/10272/21005 LA eng NO Borrero, J.
