Professor's Nutrients - Starter Soak – Ready-to-Use Nutrient & Rooting Formula

Professor's Nutrients - Starter Soak - Ready-to-Use Propagation Formula

Professor’s Starter Soak is a scientifically designed, professional-grade nutrient formula engineered to encourage young plants, cuttings, and seedlings to establish roots rapidly. Pre-mixed and ready to use straight from the bottle, this specialised soak features a perfectly balanced pH and a precise, ultra-low electrical conductivity (0.5 EC) tailored specifically for highly sensitive young root zones. It provides the ideal bridge between plain water and full-strength vegetative fertilisers.

By delivering a gentle yet complete profile of high-grade chelated micro and macro trace elements, Starter Soak ensures optimal nutrient absorption without the risk of salt burn. It is the ultimate plug, cube, and media conditioner for growers looking to accelerate early root and shoot development during the most fragile stage of the crop cycle. Using Starter Soak eliminates the guesswork, ensuring your clones and seedlings have the perfect nutritional start every time.

Best For: Pre-soaking starter plugs, rockwool cubes, and propagation media, accelerating root strike in fresh cuttings, preventing nutrient burn in delicate seedlings, and driving rapid early growth.

Key Features:

• Perfect 0.5 EC Balance: Precision-blended to a gentle 0.5 EC, offering the perfect low-strength nutritional foundation for young, vulnerable root systems.
• High-Grade Chelated Minerals: Packed with premium chelated macro and micro trace elements that are easily absorbed by young tissues, maximising nutrient mobility.
• Ready-to-Use Convenience: No measuring, mixing, or diluting required; pre-mixed at the optimum concentration and balanced pH to save valuable time in the propagation room.
• Accelerated Development: Actively stimulates early root branching while feeding tender young shoots to ensure strong, uniform early growth across your entire batch.
• Zero Salt Burn Risk: Formulated to eliminate the risk of overfeeding, ensuring fragile root hairs stay healthy, bright white, and fully functional.

Specifications:

Ideal For:

• Media Pre-Soaking: Soak your rockwool cubes or coco plugs directly in Starter Soak before inserting cuttings to establish an ideal, nutrient-rich environment.
• Early Stage Feeding: Use as the primary watering solution for newly rooted clones during their first week of development before transitioning to vegetative nutrients.
• Cloning Tray Maintenance: Apply to propagation trays to keep young root zones consistently moist, fed, and protected against early-stage deficiencies.

Usage Tip: For the best results, ensure your propagation media is allowed to drain slightly after soaking so it is moist but not waterlogged. This maintains the perfect air-to-water ratio, allowing the 0.5 EC nutrients and oxygen to work together for explosive root initiation.

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.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

• Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
• Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
