Grow-bag dimensions are only the beginning. Crop duration, plant density, coir particle blend, initial EC, expansion consistency and drainage layout determine whether a cocopeat slab will support a stable root zone through the production cycle.
Strawberry and tomato need different root zones
Strawberry systems commonly use narrower bags on elevated gutters with closely spaced plants. Long-cycle tomato crops generally require more substrate volume per plant and a root zone that preserves air capacity through repeated irrigation. Select bag size from crop, plant count and irrigation strategy—not from bench dimensions alone.
- Expanded volume per plant
- Bag dimensions and gutter fit
- Number and position of drippers
- Drain-hole position and collection
Check the coir specification
Request the pith, fibre and chip blend, expansion volume, moisture, pH, EC test method and buffering status. Washed and buffered are different claims: buffering replaces naturally held sodium and potassium with calcium, while washing primarily lowers soluble salts. Confirm the delivered batch before planting.
Commission irrigation with measurements
Hydrate slabs uniformly, form drainage openings only after full expansion and verify dripper discharge. During production, adjust irrigation using radiation, substrate moisture, crop stage and measured drain volume and EC. A fixed timer without feedback cannot respond well to changing UAE conditions.
