Fuente: WIPO "tomato" One embodiment includes a coir substrate assembly that includes a compressed coir plank. A non-woven fabric (NWF) mesh liner is wrapped around at least a bottom and partial side portions of the coir plank. The NWF mesh liner is sized to extend with a height of the coir plank after expansion and is permeable to water while trapping coir particles and absorbing tannin to reduce effluents in leachate.
