“…This research was conducted at the Centro Internacional de Producción Limpia Lope SENA located in eastern Pasto (N 01°12'48", W 0.77°15'12.9") at an elevation of 2630 m a.s.l., with a mean temperature of 12 o C and mean annual precipitation of 800 mm. The hydroponic strawberry system was established as described by Guerrero et al (2014), using two "A" structures with five 4-inch PVC tubes of 2 meters long placed on each side. The tubes were set at a 2% angle to allow irrigation and drainage.…”

“…Hydroponics is an innovative production alternative in Nariño for generating and obtaining healthy, contaminant-free (Jiménez, 2015) products that contribute to food security (Guerrero et al, 2014) and optimize the genetic potential of the plants (Arévalo, 2015). When clean production techniques are not used, strawberry can be affected by neurocysticersosis, caused by Cysticercus cellulosae and Cysticercus bovis, which contaminate the soil through pig feces or poorly decomposed organic amendments (Garcia et al, 2010) and a lack of sanitary control measures (Chaves and Alvarado, 2012).…”

This project is presented as an innovative and clean alternative that optimizes the use of small areas for strawberry (Fragaria ananassa Duch) production in the department of Nariño. This research was conducted at the Centro Internacional de Producción Limpia Lope -SENA- Regional Nariño, with the aim of evaluating physical and chemical variables of organic substrates such as coconut fiber, rice husk, and their mixtures for strawberry (Fragaria ananassa Duch) variety Albión production in a hydroponic system. Six treatments and four repetitions were performed; the treatments were 100% rice husk, 70% rice husk and 30% coconut fiber mixture, 50% of each of the substrates used, a mixture of 70% coconut fiber and 30% rice husk, 100% coconut fiber, and a control in soil with plastic cover. A comparative analysis was made between the average values obtained in the initial stage and the final stage of the experiment, evaluating physical and chemical properties such as bulk density, real density, gravimetric moisture, granulometry, pH, and electrical conductivity. The experiment showed that taking initial and final measurements of the substrates allows adequate monitoring for optimal crop development since a substrate with a high percentage of particles in the sieve <0.25, electrical conductivities greater than 2000 µS.cm-1, and an increase in bulk density can produce salinization and compaction, negatively impacting the crop.

In recent times, hydroponics has gained popularity as a viable solution to the challenges facing traditional agriculture, as it offers an environmentally friendly option with higher crop yields and improved quality, eliminating the need for soil. Despite these benefits, hydroponics still encounters significant difficulties, particularly in optimizing fertigation strategies. The literature contains several studies focusing on test benches for investigating technological recommendations related to fertigation strategies. However, there has been no proposed test bench capable of simultaneously exploring various types of fertigation strategies. In this work, HydroLab is introduced: a hydroponic module that allows for the simultaneous comparison of two types of fertigation strategies and enables remote monitoring and control through IoT functionality. Additionally, HydroLab’s potential to generate technological recommendations has been validated through a case study comparing time-based and solar radiation-based fertigation in lettuce cultivation. The case study successfully showcases the capability of HydroLab to investigate and compare different fertigation strategies. Given the global importance of food security challenges, this work is expected to contribute to the investigation of fertigation strategies in hydroponics.

“…Además, los resultados concuerdan con lo encontrado por Guerrero et al (2014) quienes hallaron diferencias significativas en los tratamientos de turba de coco mezclado con cascarilla de arroz en diferentes proporciones, así como también concuerdan con Astiz et al ( 2010) quienes mencionan que al variar las proporciones entre los sustratos varían también sus propiedades, tales como la capacidad de aireación y retención de agua y por ende el desarrollo de la planta. En cuanto al crecimiento, el modelo de crecimiento logístico sigmoideo fue el que presentó mayor ajuste similar a lo demostrado por Carranza et al (2009).…”

“…Los sustratos actúan como reserva de nutrientes (Guerrero et al, 2014); así, el crecimiento de las plantas en altura y el aumento de área foliar, es un indicador de que el medio proporcionó las cantidades necesarias y adecuadas de elementos minerales, lo que permitió el crecimiento vigoroso de las lechugas, al respecto, pudo suceder que el contenido nutricional presente en los sustratos estuvo tan homogeneizado que no generó Tabla 5. Parámetros del modelo de crecimiento logístico sigmoideo encontrados para los diferentes sustratos empleados en lechuga T1: turba negra 30% y turba de coco 70%, T2: turba negra 70% y turba de coco 30% y T3: turba negra 50% y turba de coco 50%.…”

La producción de hortalizas en sustratos se ha convertido en una gran alternativa. Por lo anterior, se evaluaron diferentes sustratos en un cultivo de lechuga en invernadero. Se utilizó un diseño en bloques completamente al azar (BCA) donde el factor de bloqueo fueron los sustratos y se establecieron tres tratamientos: T1: turba negra 30%, turba de coco 70%, T2: turba negra 70%, turba de coco 30% y T3: turba negra 50% y turba de coco 50%, para un total de 9 unidades experimentales, cada unidad experimental estuvo conformada por 10 plantas. Cada 8 días, durante 32 días, se determinó la altura de planta, masa fresca y seca de hojas y raíz, área foliar y cada 2 días, las unidades SPAD y la conductividad estomática (CE). Se presentaron diferencias significativas en las Unidades SPAD en el tiempo con un valor de 20,7. La CE presentó los mayores valores en T3 y T2 con valores de 354,2 y 366,2 mmol m-2 s–1, respectivamente. El T1 presentó el mayor valor de resistencia estomática (RE) con 7,5 m2 s mol–1. El área foliar y la altura no presentaron diferencias significativas. El T2 a los 15 días después de trasplante mostró los mayores valores de masa fresca de raíz (MFR), masa seca de raíz (MSR) y masa fresca de hojas (MFH) con 3,1 g, 0,106 g y 13,19 g, respectivamente. En la cosecha, el T3 mostró un 10% y 15% más de producción de MFH de lechuga, que los tratamientos T2 y T1, respectivamente.
