Agril Coco Chips – Horticultural Grade 10–20mm Chunky Coconut Husk for Orchids and Aroids
Price range: රු499.00 through රු599.00
Coco chips are coarse, chunky pieces of coconut husk that create large air pockets and fast-draining structure in any substrate blend. Unlike fine coco peat, chips provide macroporosity — the open channels roots need to breathe in container growing — while retaining enough moisture for healthy hydration between waterings.
Chip size 10–20mm. pH range 5.5–6.8. Low EC. Suitable for orchids, aroids, and any plant that demands an open-structure, chunky mix. Use at 30–50% by volume.
The airspace problem that fine media can’t solve
Fine growing media — coco peat, peat, potting soil — pack tightly around roots. Over time the small pore spaces fill with water, and roots sitting in saturated media begin to suffocate. Coco chips solve this by creating macropores — large, stable air gaps that water drains through quickly and that refill with oxygen between waterings. The chunks don’t compact, don’t decompose quickly, and create the root environment that epiphytes and aroids evolved in: fast-draining, air-rich, and intermittently moist.
What’s in the pack
- Coco chips — 10–20mm chunky coconut husk pieces, low EC, pH 5.5–6.8. Volume: 2.5L/5L.
- Condition — dry packed; no significant compression. Rinsing recommended before first use.
What you can use it for
- Orchid substrate — use at 50–70% as the primary component in orchid mixes, replacing or reducing bark to lower cost without sacrificing drainage.
- Aroid substrate component — blend at 30–50% with coco peat and perlite for chunky, well-draining tropical houseplant mixes.
- Semi-hydroponic medium — use as a standalone medium in deep pots with passive hydroponics (wick or reservoir system).
- Drainage layer — place a 3–5cm layer of chips at the base of large containers before adding finer substrate to prevent compaction at the drain hole.
- Terrarium substrate layer — use as an aeration layer between drainage stone and growing medium in bioactive terrarium setups.
Preparing coco chips before use
- Rinse thoroughly in a colander or mesh bag under running water. This removes loose fibre, dust, and initial EC from the surface of the chips. Continue until water runs mostly clear.
- Soak for 30–60 minutes in clean water to pre-saturate the chip structure. This reduces the initial rapid drying cycle after potting and helps stabilise the moisture environment for new roots.
- Drain fully before using. Shake out excess water — chips should feel damp, not dripping. They are now ready to use as a standalone medium or blending component.
Mixing into an aroid or tropical substrate
- Measure your components — a standard chunky aroid mix: coco chips 30%, coco peat 30%, perlite 25%, worm castings 10%, orchid bark 5%.
- Combine in a large tray and mix evenly. The chips are bulky — fold rather than stir to distribute without breaking the chunks.
- Pot your plant — fill the pot loosely without pressing down. The irregular chip shapes create natural air gaps; compacting the mix defeats the purpose.
- Water thoroughly after potting to settle the substrate and initiate root contact. Allow to drain fully before placing on a saucer.
Using as a standalone orchid medium
- Rinse and soak as above. For orchids, use chips at 60–70% combined with orchid bark at 20–30% and perlite at 10%.
- Pot the orchid with roots spread naturally — do not force roots into the mix. Fill around roots with chips and bark, tap the pot to settle.
- Water when chips are mostly dry — lift the pot to judge weight. Orchids in chip-based mixes dry faster than bark-only mixes; check every 5–7 days.
Tips for best results
- Always rinse before use — skipping this step leaves fine fibre and surface EC in the mix, which can stress roots initially.
- Don't crush or break chips during mixing — the chunk size is what creates macroporosity; broken pieces behave like fine media.
- Repot when chips compact — check substrate structure every 12 months; when the mix no longer drains as quickly as when first potted, it's time to refresh.
What's the difference between coco chips and coco peat — can I use them interchangeably?
No. Both come from coconut husk but behave very differently. Coco peat is fine-fibred with high moisture retention — it's a base medium. Coco chips are 10–20mm chunks with high macroporosity and faster drainage — they're a structural component. They work best in combination: coco peat provides moisture retention, chips provide airspace. Neither fully replaces the other.
Can I use coco chips as the only medium — without mixing?
For epiphytic orchids and some aroids with thick aerial roots, yes — chips alone in a deep pot with adequate watering frequency can work well. For most tropical houseplants, a pure chip substrate dries too fast between waterings. A 50–70% chip blend with coco peat or bark is more forgiving for everyday growing.
How long do coco chips last before breaking down?
Coco chips are slower to decompose than fine coco peat, but they do break down — typically 18–24 months in a container before the chunk structure begins to compact noticeably. When drainage slows and the mix feels denser than when first potted, it's time to repot with fresh chips. Unlike LECA pellets, coco chips are not reusable — compost the spent medium.
Are coco chips suitable for Phalaenopsis orchids?
Yes, coco chips work well for Phalaenopsis and most other epiphytic orchids. Use at 60–70% combined with orchid bark for best results. Coco chips dry slightly faster than bark alone, so check your watering frequency after switching. If your Phalaenopsis is used to bark-based mixes, give it 2–3 watering cycles to adjust to the new drying pattern.
Why do I need to rinse coco chips before use?
Fresh coco chips carry surface EC from residual natural salts in the coconut husk and loose fibre particles from processing. Rinsing removes both — it reduces the initial EC spike that can stress newly potted roots, and it flushes out fine particles that would otherwise compact between the chunks and reduce macroporosity.
Can coco chips replace LECA pellets in semi-hydroponic setups?
Partially. Coco chips can be used in passive hydroponic setups with a reservoir, and they work well for this. The key difference is longevity — LECA pellets are inert, reusable, and last indefinitely; coco chips decompose over 18–24 months and will need replacing. If you plan to maintain a long-term semi-hydroponic setup, LECA is more practical. Coco chips are a good lower-cost alternative for medium-term use.
My coco chips look very fibrous with lots of loose strands — is that normal?
Yes. Coco chips are cut from the fibrous outer husk, and some loose strands are a normal part of the product. They don't affect performance. If you want a cleaner mix, rinse and shake the chips in a mesh bag before use to remove excess loose fibre. The chunks themselves should be firm and hold their shape when squeezed.
