Understanding the water\u2013air curve is crucial. Easily available water is that which the substrate releases between 10 and 50 cm tension; the buffer capacity between 50 and 100 cm cushions demand peaks; and the point where water volume equals air volume indicates whether the medium breathes while hydrating. With more fine pith, the reserve increases, but usable air decreases; with coarser fractions, air increases, but irrigation must be more frequent to maintain hydration during the plant\u2019s peak activity hours. In strawberries, this balance is critical, as oxygenated roots and stable water determine fruit quality and firmness (Durand et al., 2023).<\/p>\n

Designing Coco-Only Mixes<\/strong><\/p>\n Working solely with coco allows modulation of air and water by combining fine pith with coarser coco fractions. The choice depends on climate and the irrigation system:<\/p>\n Container shape also influences outcomes: the shorter the substrate column, the lower the total aeration. Deeper pots allow better root oxygenation, translating technical adjustments into uniform growth and consistent fruit (Rivera-del R\u00edo et al., 2015; Palencia et al., 2016).<\/p>\n Water, Salts, and Structural Stability<\/strong><\/p>\n Some coco batches contain residual Na\u207a and K\u207a, requiring washing with fresh water and sometimes buffering with calcium nitrate before starting the crop. The advantage of coco over other media like peat is its excellent rehydration and water retention capacity with high lignin content, ensuring structural stability throughout the cycle. In practice, shrinkage >5% should be avoided, as it can affect roots and complicate daily management.<\/p>\n Controlling drainage, EC, and pH is not bureaucracy; it is the tool that allows correction of salt accumulation before it impacts vigor and yield. Thus, strawberries in coco achieve irrigation patterns that synchronize water, air, and nutrients, ensuring firm fruit and continuous harvests (Durand et al., 2023; Konduru et al., 1999).<\/p>\n Practical Observations<\/strong><\/p>\n Studies in protected structures show that the substrate explains much of the variation in biomass, crowns, and leaf area. The success of working with \u201ccoco-only\u201d mixes lies in selecting the correct particle size and coordinating it with irrigation: coarser fractions require more pulses and shorter pauses; finer fractions need longer pauses to reoxygenate the substrate and prevent hidden water accumulation. This approach ensures that roots receive constant oxygen and stable water, regaining control over daily crop management.<\/p>\n References<\/strong><\/p>\n Strawberries perform best when the roots can breathe and the root ball doesn\u2019t change \u201cmood\u201d every hour. In substrate cultivation, this is achieved with a medium that combines sufficient air pores and easily available water. Coco can fulfill this role if properly formulated and carefully managed.
