Abstract
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.
Claims20
A coir substrate assembly, comprising:
- a compressed coir plank;
- and
- a non-woven fabric (NWF) mesh liner wrapped around at least a bottom and partial side portions of the coir plank;
- wherein 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.
1 more element
A grow bag system for hydroponic cultivation with reduced leachate effluents, comprising:
- a non-permeable grow bag configured for one or more plant holes on a top surface and one or more drain holes along bottom side margins;
- a compressed coir plank disposed within the grow bag;
- and
- a non-woven fabric (NWF) mesh liner wrapped around at least a bottom and side portions of the coir plank,
- wherein the NWF mesh liner is permeable to water and configured to trap coir and solid particles and reduce tannin in drainage passing through the drain holes.
2 more elements
A method for preparing a coir-based substrate with reduced leachate effluents, comprising:
- providing a compressed dry coir plank;
- positioning a non-woven fabric (NWF) mesh liner underneath the compressed coir plank;
- and
- wrapping the compressed coir plank with the NWF mesh liner so as to cover at least a bottom surface and side portions of the plank;
- wherein, upon hydration and expansion of the coir plank, the NWF mesh liner permits drainage flow without waterlogging, and filters the drainage to reduce particle outflow and tannin emission in leachate.
