“…The engineering of durable substrates which can be reused over multiple crop cycles for hydroponic production has also gained attention recently [76][77][78]. Recycled plastic planks which are typically marketed as drainage materials show potential as a hydroponic substrate and for incorporation into green roofs [79,80].…”

Conventional soilless growing media, such as perlite, are mined from nonrenewable resources and can only be disposed of in landfills after limited use. There is a need to investigate novel, sustainable growing media adapted from waste or engineered to be reused over multiple cycles. This study investigated waste almond shells and a recycled plastic drainage plank as hydroponic growing media alternatives. Physiochemical properties were evaluated, and a germination and greenhouse growth trial was conducted to understand the effect these media have on production and nutritional quality of lettuce (Lactuca sativa L. cv. Catalogna Verde). Drought testing was carried out to understand how the media affected the lettuce’s response to water stress. In comparison to perlite, yields under regular irrigation were reduced by 52% in almond shells and 72% in plastic planks, although lettuce grown in almond shells still obtained commercially relevant yields. Reduced yields in almond shells were likely caused by the shell’s high salinity. Lettuce growth in plastic planks was limited by impeded root growth and low water-holding capacity. In conclusion, with minor alterations, almond shells could be used as a sustainable growing media alternative to perlite in hydroponic lettuce production. More research is needed to manufacture the planks to be conducive to plant growth.

“…En los últimos años, los investigadores informaron que los hidrogeles naturales a base de celulosa pueden servir como medios de cultivo para conservar el agua y los nutrientes, por lo tanto, tienen un gran potencial en el cultivo sin suelo para el crecimiento de las Revista de Ciencias Tecnológicas (RECIT). Volumen 6 (3): e256 hortalizas [13][14][15], debido a su propiedad de retención de agua, los hidrogeles tienen la capacidad de mejorar la soltura y la porosidad del suelo, mejorar la capacidad de acumulación de humedad y promover la capacidad de los sistemas de raíces de las plantas, la germinación de semillas y la supervivencia de las plantas [15]. La Microtomografía Computarizada (Micro-CT) es una técnica de imágenes en 3D que utiliza rayos X para ver el interior de un objeto, corte por corte.…”

El cultivo sin suelo es una técnica de la agricultura que permite un mayor rendimiento en los cultivos, mostrando varias ventajas sobre la agricultura tradicional, esta técnica requiere de mejoras en los sustratos utilizados para obtener mayor producción y calidad. Los hidrogeles derivados de celulosa prometen ser una buena alternativa como sustrato por sus propiedades hidrofílicas sin embargo carecen de una buena aireación. Se propone utilizar la celulosa como materia prima para la síntesis de hidrogeles a base de celulosa asistido por la microtomografía computarizada para generar un modelo con una porosidad de 15-30% y reproducirlo mediante impresión 3D por procesamiento de luz digital (DLP). Por lo tanto, se busca obtener un sustrato de hidrogel de celulosa con mejores propiedades que los sustratos comerciales, e implementar la impresión 3D en la agricultura.
