Professor's Nutrients - Hydro Clay (50L) Pallet of 44 – Bulk 2200L Commercial Expanded Clay Aggregate (LECA)

Professor’s Nutrients - Hydro Clay (50L) – Bulk Commercial Pallet of 44 Bags (2,200L Total)

Engineered for high-performance commercial hydroponic systems, large-scale wholesale nurseries, and industrial agricultural facilities, this bulk pallet listing includes forty-four individual 50-Litre sacks (2,200 Litres total volume) of Professor’s Nutrients Hydro Clay. This premium Lightweight Expanded Clay Aggregate (LECA) is a high-performance substrate manufactured by firing premium natural clay in a rotary kiln at extreme temperatures. This process causes the clay to expand into highly porous, lightweight spheres with a varying diameter of 8–16mm. Featuring a rigid, sterile outer shell and a micro-porous internal core, Hydro Clay provides the ultimate structural foundation for rapid root zone aeration and instant drainage.

Purchasing this product in a full commercial pallet of 44 bags provides the most cost-effective bulk medium solution for large facilities. It is ideal for scaling up extensive recirculating commercial greenhouse systems or packing out vast industrial crop benches. Completely inert, chemically neutral, and structurally stable, Hydro Clay ensures it will not break down, compact, or alter your water reservoir’s nutrient balance over long, high-frequency crop cycles.

Best For: Large-scale Deep Water Culture (DWC) arrays, automated flood-and-drain (ebb and flow) tables, commercial top-feed drip systems, commercial aquaponics, industrial pot-lining drainage layers, and wholesale potting mix aeration amendments.

Key Features:

• Commercial Bulk Logistics: Supplied as a full freight-wrapped pallet of 44 heavy-duty 50L bags, delivering a massive 2,200 Litres of premium media to your loading dock for major commercial build-outs.
• Optimised 8–16mm Mixed Sizing: The varying diameter of the clay balls ensures they interlock cleanly within large net pots, crop baskets, and drainage channels, providing superior structural support for heavy plants while leaving massive macro-porous air gaps.
• Maximum Root Zone Aeration: By maintaining an open, uncompactable matrix, Hydro Clay ensures that fresh oxygen is constantly available to the rhizosphere, driving explosive lateral root development and protecting against root rot (Pythium).
• 100% Inert & pH Neutral: Unlike inferior clay resources that can cause aggressive pH spikes, Professor's Hydro Clay is pre-stabilised and completely neutral, giving you absolute control over your precision liquid nutrient feeding regime.
• Infinite Reusability & Asset Value: Highly durable and physically robust, these clay pebbles do not degrade or dissolve. They can be thoroughly washed, sterilised, and reused harvest after harvest, making this bulk pallet an incredibly cost-effective long-term infrastructure investment.
• Sterile & Pathogen-Free Base: The high-heat kiln manufacturing process ensures the medium is completely sterile upon packaging, entirely free from weeds, pests, harmful bacteria, and soil-borne diseases.
• Excellent Capillary Action: The porous internal core absorbs moisture and dissolved nutrients, drawing them upward to feed young roots while allowing excess surface water to drain away instantly.

Preparation & Hydroponic Management Tips:

• The Initial Bulk Rinse: Like all LECA products, Hydro Clay can develop a fine clay dust during transit. Before introducing it to your active system rows, rinse the pebbles thoroughly with fresh water until it runs completely clear.
• Pre-Soaking for Stability: For best results in recirculating hydroponic setups, soak your rinsed clay pebbles in a pH-adjusted water bath (5.5–5.8) for 24 hours prior to planting. This fully saturates the internal pores and locks in your target baseline.
• Deep Water Culture (DWC) Staging: When using Hydro Clay in net pots, drop your rooted starter plug or cube onto a solid base layer of pebbles, then carefully fill around the stem. This blocks out overhead light from reaching the lower water reservoir, preventing costly algae outbreaks.
• Sterilising Between Cycles: To reuse your Hydro Clay, strip out the old root mass, rinse the pebbles to remove organic debris, and soak them in a diluted hydrogen peroxide or commercial sanitising solution. Rinse once more with fresh water, and the media is ready for the next crop run.

Ideal For:

• Recirculating Hydroponics: The absolute gold standard medium for massive commercial flood-and-drain tables, top-feed drip rings, or large-scale DWC systems where fast, clean water movement is essential.
• Base Drainage Layer: Placing a uniform 2–3cm layer at the bottom of standard potting soil or coco coir containers to prevent pooling water and ensure flawless systemic drainage.
• Aroid & Indoor Potting Mixes: Blending into dense potting soils to lighten the overall weight of the commercial container lines and instantly introduce permanent aeration pockets for indoor tropicals like Monsteras and Alocasias.

Commercial Logistics Note: Pallet pricing is shown. Full commercial pallet shipments require a suitable forklift or loading dock facility on-site for delivery. Please contact our trade desk directly on 0418 438 774 for an accurate freight and shipping quote to your specific facility.

Oversized Item Delivery Options

Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.

Available options include:

✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)

Important Notes:

• Shipping costs vary by location and method
• Any carton or consignment over 25–30kg (or over 200cm) must be palletised
• Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
• Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
• Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions

Business Delivery:

• Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
• If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

See our Terms & Conditions (Article 8) for full freight and delivery rules.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.
