It also helps prevent the build-up of nutrient deposits at the root zone itself, addressing blockages at both ends of the irrigation system rather than just the hardware.\u003c\/p\u003e\u003cp\u003eRestrictive feed outlets like drippers are especially prone to blocking with salt build-up, dirt, algae, root growth and growing medium debris, and once a blockage starts it tends to compound — a partially blocked dripper feeds unevenly, which stresses the plant and encourages roots to grow toward the outlet, making the blockage worse. StopBloc is compatible with any type of nutrient, fertiliser, system or substrate, and is used through both vegetative and flowering stages as ongoing protection rather than a one-off fix, alongside good practice such as maintaining pH below 6.5 and routine reservoir flushing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eResists nutrient deposit build-up\u003c\/strong\u003e in feed-lines, drippers, pumps and filters\u003c\/li\u003e\n\u003cli\u003eAlso protects against \u003cstrong\u003eroot-zone deposit build-up\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible with any nutrient, system or substrate\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eUsed continuously through \u003cstrong\u003evegetative and flowering\u003c\/strong\u003e stages\u003c\/li\u003e\n\u003cli\u003eComplements good irrigation hygiene rather than replacing it\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDose rate: 0.5ml\/L\u003c\/li\u003e\n\u003cli\u003eWhen to use: seed to harvest, veg and bloom\u003c\/li\u003e\n\u003cli\u003eSuitable media: hydroponics, coco, soil\u003c\/li\u003e\n\u003cli\u003eCompatible with all nutrient brands and irrigation systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"hcs-dosing\" style=\"margin:32px 0 0;border:1px solid #e6e6e6;border-radius:12px;overflow:hidden;font-family:Montserrat,-apple-system,'Segoe UI',sans-serif;\"\u003e\n\u003cdiv style=\"background:#101010;padding:16px 20px;border-bottom:3px solid #efc04c;\"\u003e\n\u003cdiv style=\"color:#ffffff;font-size:17px;font-weight:600;letter-spacing:.06em;text-transform:uppercase;\"\u003eFeed Chart\u003c\/div\u003e\n\u003cdiv style=\"margin-top:6px;color:#b8b8b8;font-size:12px;line-height:1.5;\"\u003eFlairform StopBloc · hydroponics, coco and soil\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;color:#2b2b2b;background:#fff;\"\u003e\n\u003ctr style=\"background:#f4f4f4;\"\u003e\n\u003cth style=\"text-align:left;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;\"\u003eStage\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 14px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 1 L\u003c\/th\u003e\n\u003cth style=\"text-align:right;padding:10px 20px;font-size:11px;letter-spacing:.08em;text-transform:uppercase;color:#6b6b6b;font-weight:600;white-space:nowrap;\"\u003ePer 10 L\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eEvery stage, on both the soft-water and hard-water charts\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e0.5 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e5 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"background:#101010;padding:12px 20px;font-size:12px;color:#b8b8b8;line-height:1.6;\"\u003e\n\u003cspan style=\"color:#efc04c;font-weight:600;\"\u003eNote\u003c\/span\u003e — The rate does not change across the chart. Flairform's separate 0.2 ml\/L figure belongs to Pythoff, not to StopBloc. Fill the reservoir with water then add each product, stirring thoroughly after each addition. Never add chlorine, peroxide or pre-mix products in concentrated form. Check pH is between 5.0 and 6.3 immediately — on hard water the nutrient is more stable if brought quickly to 5.0–5.5. Flairform: “This dose chart serves as a guide only.” Check pH and EC after mixing.\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Flairform","offers":[{"title":"500ml","offer_id":53500724707594,"sku":"NUT-FLAI-006-01","price":9.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/stopbloc-500x500.jpg?v=1786377661","url":"https:\/\/hydrocropshop.co.uk\/products\/flairform-stopbloc","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
