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.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast-Acting Lockout Correction:\u003c\/strong\u003e Rapidly dissolves the mineral \"crust\" that forms on root surfaces and within substrates, immediately restoring the plant's ability to uptake water and nutrients.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimised Root Environment:\u003c\/strong\u003e Reduces EC (Electrical Conductivity) levels in the medium, creating a balanced, low-stress environment that encourages healthy, white root growth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Harvest Purity:\u003c\/strong\u003e 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.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVascular Cleansing:\u003c\/strong\u003e Helps clear the plant's internal transport systems of excess minerals, ensuring that the final produce burns cleaner and maintains its natural terpene profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe \u0026amp; Effective:\u003c\/strong\u003e A gentle yet powerful formula that effectively leaches minerals without causing the osmotic shock often associated with using plain water for flushing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e The Professor’s Nutrients\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Mineral Leaching Agent \u0026amp; Substrate Conditioner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication Phase:\u003c\/strong\u003e Mid-cycle (for lockout) or Final Flush (last 7-10 days of Bloom)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media:\u003c\/strong\u003e Hydroponics, Coco Coir, Rockwool, and Soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable Sizes:\u003c\/strong\u003e 1 Litre and 5 Litre\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmergency Nutrient Reset:\u003c\/strong\u003e The go-to treatment for plants showing signs of \"burnt\" tips or stalled growth due to over-fertilisation or salt-choked media.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnoisseur Quality Finishing:\u003c\/strong\u003e Essential for the final stage of flowering to ensure the smoothest possible experience and the most authentic expression of the plant's flavour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate Rejuvenation:\u003c\/strong\u003e Excellent for periodic maintenance in long-term vegetative plants to prevent the gradual build-up of unabsorbed mineral salts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"1L","offer_id":48389359861860,"sku":"4315","price":18.9,"currency_code":"AUD","in_stock":true},{"title":"5L","offer_id":48389359894628,"sku":"4316","price":71.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/PN-Ultra-Flush-1L.jpg?v=1778250657","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/the-professor-s-nutrients-ultra-flush-advanced-mineral-flush-lockout-treatment","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
