Agril BioBoost Coco Chips — Trichoderma-Enriched 10–20mm Coconut Husk for Orchids and Aroids
Price range: රු499.00 through රු699.00
BioBoost Coco Chips combine the macroporous drainage structure of 10–20mm coconut husk chunks with supplier-blended enrichments: a Trichoderma-based biological fungicide, plant-derived rooting hormone, and a balanced starter fertiliser — giving roots both the physical space to expand and the biological environment to establish faster.
Chip size 10–20mm. pH 5.5–6.8. Low EC. Sterile base. No additional fungicide treatment required for the first 6–8 weeks. Purpose-built for orchids, aroids, and epiphyte mixes where establishment speed and root health matter.
Chunky structure. Biological protection. In one substrate.
BioBoost Coco Chips start with the same 10–20mm coconut husk chunks that make standard coco chips a reliable macroporous substrate component. The difference is what’s blended in: a living Trichoderma culture that colonises root surfaces and suppresses fungal pathogens from day one, a plant-derived rooting hormone that promotes lateral root branching in the open-structure environment chips create, and a starter fertiliser that provides early nutrition without requiring a separate feed at transplant.
For orchids, aroids, and epiphytes — where root health is directly visible and rot is a constant risk — the combination of physical structure and biological protection makes a meaningful difference in establishment outcomes.
What’s in the pack
- BioBoost Coco Chips — 10–20mm coconut husk chunks, pH 5.5–6.8, low EC, enriched with Trichoderma, rooting hormone, and starter fertiliser. Volume: 2.5L/5L.
- Condition — dry packed; rinse lightly before use to remove loose fibre without flushing enrichments.
What the three enrichments do in a chunky substrate
- Trichoderma biological fungicide — in the high-airflow, fast-drying environment that coco chips create, Trichoderma thrives particularly well. It colonises root surfaces, outcompetes Pythium and Fusarium, and remains active as long as conditions are favourable. This is especially valuable for orchids, which are prone to root rot if moisture lingers.
- Rooting hormone (plant-derived) — promotes lateral root initiation in the macropore spaces between chips, encouraging the dense, wide-spreading root systems that orchids and aroids develop naturally in epiphytic conditions.
- Starter fertiliser — provides accessible early nutrition in a substrate that is otherwise nutritionally inert, removing the need to begin a fertiliser programme immediately after potting.
What you can use it for
- Orchid repotting — use at 60–70% with orchid bark; Trichoderma protection is particularly effective in the high-moisture-risk orchid root zone.
- Aroid substrate blends — blend at 30–50% with BioBoost or standard coco peat and perlite for a biologically active, open-structure tropical mix.
- Epiphyte mounting — pack around mounted Hoyas, Anthuriums, and other epiphytes where Trichoderma protection reduces damping off at attachment points.
- Premium propagation medium — use as the structural component in propagation setups where biological protection and rooting hormone are both needed.
Preparing BioBoost Coco Chips
- Rinse briefly in a colander under running water — 20–30 seconds is sufficient. This removes loose fibre and surface dust without washing away the biological enrichments embedded in the chip structure.
- Do not soak for extended periods. Unlike standard coco chips where a 30–60 minute soak is recommended, BioBoost chips should only be briefly rinsed to preserve Trichoderma viability on the chip surface. A 5-minute light soak is acceptable if needed for pre-saturation.
- Drain and use immediately. BioBoost Coco Chips are most effective when planted fresh after rinsing — Trichoderma begins colonising root surfaces fastest in the first 24–48 hours after potting.
Using in an orchid or aroid mix
- Measure components — for orchids: BioBoost Coco Chips 60%, orchid bark 30%, perlite 10%. For aroids: BioBoost Coco Chips 35%, coco peat 35%, perlite 20%, worm castings 10%.
- Combine gently in a mixing tray. Fold the components together — avoid vigorous stirring that might break the chips.
- Pot immediately after mixing — fill loosely, settle by tapping the pot sides, and do not compress.
- Water lightly after potting and allow to drain fully. Do not fertilise for 4 weeks — the starter fertiliser in the chips provides early nutrition.
Tips for best results
- Do not use chemical fungicide drenches for the first 6–8 weeks — they will suppress the Trichoderma colony.
- Hold off on extra fertiliser for 4 weeks — the starter fertiliser in the chips is sufficient for establishment.
- Use within 6 months of purchase for full biological effectiveness — Trichoderma viability declines over time even in sealed storage.
- Store in a cool, shaded location — heat above 30°C in storage reduces Trichoderma shelf life.
Why should I choose BioBoost Coco Chips over standard Coco Chips?
If you're repotting or propagating plants where root rot is a risk — orchids, newly rooted aroids, plants with compromised root systems — the Trichoderma protection in BioBoost chips provides a meaningful biological safety net. For healthy, established plants in open, well-draining conditions, standard chips may be sufficient. BioBoost is the higher-value option for higher-risk potting situations.
Can I use BioBoost Coco Chips with my usual orchid fertiliser?
Yes, but wait 4 weeks. The starter fertiliser in the chips provides early nutrition — adding additional fertiliser in the first 4 weeks risks overfeed stress on newly potted roots. After week 4, resume your normal fertiliser programme. Avoid using fertilisers that contain synthetic fungicide components, as these may suppress the Trichoderma colony.
I usually soak coco chips for an hour before potting — should I do the same with BioBoost?
No. A brief rinse (30 seconds to 5 minutes maximum) is recommended for BioBoost Coco Chips. Extended soaking washes away the biological enrichments from the chip surface before Trichoderma has had the chance to establish in the root zone. The brief rinse removes loose fibre and dust without compromising the active inputs.
I see white fuzzy growth on my chips after potting — is that mould?
It's most likely Trichoderma mycelium — the visible thread-like growth of the fungal culture as it activates and spreads through the substrate. Trichoderma mycelium is white to pale green and appears as fine, web-like growth between the chips. It is beneficial and harmless. If the growth is grey, black, or has a foul odour, that is a different fungal species — in that case, contact us within 7 days of delivery.
How long does the Trichoderma remain effective in the pot?
Once established in the root zone, Trichoderma continues to colonise and self-propagate as long as the conditions are suitable (moisture, organic matter, temperature 15–35°C). A healthy Trichoderma colony can remain active for the life of the substrate — typically 18–24 months. If you use chemical fungicide drenches, the colony will be suppressed and effectiveness reduced.
Can I mix BioBoost Coco Chips with standard Coco Peat, or does it have to be BioBoost Coco Peat?
You can mix with standard Agril Coco Peat — there is no chemical incompatibility. The Trichoderma in the chips will colonise the root zone regardless of whether the peat component is enriched. Using BioBoost Coco Peat alongside BioBoost Chips simply increases the overall Trichoderma inoculation density, which can improve establishment speed in high-risk situations but is not a requirement for normal use.

Sphagnum Moss — Long-Fibre Horticultural Grade, Air-Dried, High Water Retention
Sphagnum moss is a long-fibre, naturally acidic growing medium harvested and air-dried for horticultural use. Its hollow capillary fibre structure holds water at up to 20× its dry weight while maintaining sufficient airflow around roots — a balance very few substrates achieve. Slightly acidic pH (4.0–5.0) makes it well-suited for moisture-loving, acid-preferring plants.
Long-fibre horticultural grade. pH 4.0–5.0. Air-dried. Ideal for Monsteras, Anthuriums, Hoyas, terrariums, moss poles, and orchid mounting. Soak for 5–10 minutes before use.
Horticultural Charcoal — Sustainably Sourced Selected Hardwood, Toxin Adsorption, Terrarium Grade
Agril Horticultural Charcoal is produced by slow-burning selected hardwoods chosen specifically for their low resin content and clean burn profile — resulting in a pure, mineral-rich carbon amendment free from resinous contaminants. The porous carbon structure adsorbs excess salts, organic waste compounds, and volatile impurities that accumulate in closed or low-drainage container environments, helping maintain substrate freshness over time.
pH approximately 7.0–8.5. Sustainably sourced hardwood. Use at 5–10% in terrariums, closed systems, and any substrate where long-term hygiene and toxin control are priorities. Not a substitute for activated carbon in aquatic systems.
Agril Horticultural Grade Perlite (3–6mm) — Zip-lock Pouch
Most plant roots drown long before they dry out. Perlite is the simplest way to add instant drainage and essential air pockets to heavy potting soils, keeping your tropicals and succulents breathing comfortably.
These lightweight volcanic glass pearls prevent soil compaction while holding onto nutrients for slow release. It sits at a neutral pH, making it completely safe for sensitive roots. Just remember to dampen it before mixing—dry perlite dust isn't something you want to breathe in.
Clay Pellets (LECA) — Lightweight Expanded Clay Aggregate, Reusable, pH Neutral
Clay pellets — also known as LECA (Lightweight Expanded Clay Aggregate) — are kiln-fired clay spheres with a porous internal structure and a hard, stable outer shell. pH neutral, chemically inert, and reusable indefinitely with proper cleaning, they create excellent drainage channels, prevent substrate compaction, and work as a standalone semi-hydroponic medium or a structural drainage layer beneath finer media.
Particle size 8–16mm. pH neutral. Sterile. Suitable for semi-hydroponic growing, passive hydroponics, drainage layers, and open-structure aroid substrate blends.

Burned Rice Husk — Carbonised Rice Hull Biochar, Permanent Drainage Amendment, Sterile
Burned rice husk is fully carbonised rice hull — a black, lightweight biochar material produced by controlled high-temperature combustion of paddy husks. Its porous carbon matrix improves drainage, increases aeration, and provides long-lasting physical structure in any substrate blend. Unlike organic amendments, carbonised rice hull does not decompose and contributes stable, permanent porosity to the mix.
pH approximately 7.0–8.5 (slightly alkaline). Sterile. Weed-free. Long-lasting structural amendment. Use at 10–20% by volume in mixed substrates. Pair with worm castings or fertiliser for nutrition — carbonised husk is not a nutrient source.
Worm Castings — Pure Vermicompost, Slow-Release Organic Nutrition, Odour-Neutral
Worm castings are the finished vermicompost output of earthworms processing organic matter — a dense, nutrient-rich amendment that feeds soil biology, improves structure, and provides gentle slow-release nutrition without burn risk at recommended ratios. Unlike synthetic fertilisers, castings simultaneously improve microbial activity, water retention, and nutrient availability.
NPK approximately 1–0.7–1.1 with a rich micronutrient and humic acid profile. Odour-neutral. Safe for all plants including seedlings. Use at 10–20% by volume in any substrate blend or as a top-dress amendment.
