{"product_id":"grotek-final-flush","title":"Grotek Final Flush","description":"\u003ch2\u003eA Fast, Thorough Pre-Harvest Salt Strip\u003c\/h2\u003e\u003cp\u003eRepeated feeding leaves fertiliser salts behind in the growing medium and, over time, absorbed into plant tissue itself. That build-up shows up as a white, powdery residue on the surface of the medium, and left unaddressed it can leave a bitter edge in the finished harvest. Final Flush is a dedicated flushing agent designed specifically to correct that over-feeding and clear the medium during the final stages of the grow, rather than relying on plain water alone.\u003c\/p\u003e\u003cp\u003eThe difference from a straight water flush is that plain water only shifts salts that are already dissolved in the medium. Final Flush contains solubilizers that actively liquify salts that have precipitated out and bonded to the growing medium, pulling them into solution so they can be flushed away along with the dissolved fraction. That distinction matters most in coco and peat-based substrates, where salts bind more readily than they do in an inert hydro medium.\u003c\/p\u003e\u003cp\u003eIt's flexible enough to use as routine maintenance mid-grow when salt build-up is suspected, to correct an overfeeding mistake, or as a dedicated pre-harvest step to clear the plant's system and let its natural aroma and flavour come through in the final product.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDissolves precipitated salts\u003c\/strong\u003e - goes further than plain water by liquifying bonded salt deposits, not just dissolved ones\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrects over-feeding\u003c\/strong\u003e - brings an over-fertilised crop back into balance quickly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproves natural aroma and flavour\u003c\/strong\u003e - clears residual fertiliser taste ahead of harvest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe mid-cycle or pre-harvest\u003c\/strong\u003e - can be used as routine maintenance or as a dedicated finishing step\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks across grow systems\u003c\/strong\u003e - suited to hydroponics, coco and soil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple mix-and-run application\u003c\/strong\u003e - no complex dosing schedule required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cp\u003eApplication rate: 10ml per 5 litres of water (2ml per litre).\u003cbr\u003eHydroponics: add to pure water in the reservoir and circulate through the system for approximately one hour.\u003cbr\u003eSoil\/coco: apply liberally to the top of the container, allow excess to drain, repeat if needed, then rest one week before resuming a regular feed programme.\u003cbr\u003ePre-harvest use: apply 7-10 days before harvest.\u003c\/p\u003e","brand":"Grotek","offers":[{"title":"Blueberry","offer_id":53500729950474,"sku":"GRTK-FF-BLUE-1L","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"Grapefruit","offer_id":53500729983242,"sku":"GRTK-FF-GRPF-1L","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"Green Apple","offer_id":53500730016010,"sku":"GRTK-FF-GAPL-1L","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"Piña Colada","offer_id":53500730048778,"sku":"GRTK-FF-PICO-1L","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"Regular","offer_id":53500730081546,"sku":"GRTK-FF-REG-1L","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"Strawberry","offer_id":53500730114314,"sku":"GRTK-FF-STRW-1L","price":12.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/Grotek_Final_Flush_Blueberry_1_liter_main_image_1050_x_1050.jpg?v=1786377741","url":"https:\/\/hydrocropshop.co.uk\/products\/grotek-final-flush","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
