Professor’s Nutrients - Ultra Flush – Advanced Mineral Flush & Lockout Treatment
The Professor’s Ultra Flush is the ultimate solution for growers facing the challenges of salt accumulation and nutrient lockout. In high-performance hydroponic systems, the rapid delivery of mineral salts can often lead to a "choked" root zone, where excess ions bond to the substrate and prevent the plant from absorbing essential nutrition. Ultra Flush is specifically engineered to break these chemical bonds, dissolving stubborn salt build-up and restoring the osmotic balance of the rhizosphere. By clearing these nutrient pathways, Ultra Flush not only saves crops from deficiency-induced stalls but also acts as a premium finishing agent. Using it during the final stage of flowering ensures the removal of chemical residues, resulting in a cleaner, smoother, and higher-quality harvest with superior flavour and aroma.
Best For: Correcting nutrient lockout, removing toxic salt accumulations from all growing media, restoring root zone health mid-cycle, and flushing plant tissues prior to harvest for improved quality.
Key Features
- Fast-Acting Lockout Correction: Rapidly dissolves the mineral "crust" that forms on root surfaces and within substrates, immediately restoring the plant's ability to uptake water and nutrients.
- Optimised Root Environment: Reduces EC (Electrical Conductivity) levels in the medium, creating a balanced, low-stress environment that encourages healthy, white root growth.
- Enhanced Harvest Purity: When used as a final flush, it forces the plant to process its internal nutrient reserves, eliminating the harsh "metallic" taste often associated with synthetic fertilisers.
- Vascular Cleansing: Helps clear the plant's internal transport systems of excess minerals, ensuring that the final produce burns cleaner and maintains its natural terpene profile.
- Safe & Effective: A gentle yet powerful formula that effectively leaches minerals without causing the osmotic shock often associated with using plain water for flushing.

Ideal For (Uses)
- Emergency Nutrient Reset: The go-to treatment for plants showing signs of "burnt" tips or stalled growth due to over-fertilisation or salt-choked media.
- Connoisseur Quality Finishing: Essential for the final stage of flowering to ensure the smoothest possible experience and the most authentic expression of the plant's flavour.
- Substrate Rejuvenation: Excellent for periodic maintenance in long-term vegetative plants to prevent the gradual build-up of unabsorbed mineral salts.

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.
