Run early, in the first week of flower, it triggers a faster and more even switch into bloom. Run again late, in the final couple of weeks before harvest, the same additive hardens up bud structure, adding density and weight to flowers that would otherwise finish looser and lighter.\u003c\/p\u003e\u003cp\u003eIt works as a foliar and root-zone stimulant rather than a feed — there's no NPK claim behind it, and growers dose it on top of an existing nutrient programme at the two windows where it has the most effect, rather than running it continuously through the whole cycle.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriggers rapid flower onset\u003c\/strong\u003e when used in week one of bloom\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardens and densifies buds\u003c\/strong\u003e when used in the final ripening weeks\u003c\/li\u003e\n\u003cli\u003eWorks alongside any existing base nutrient programme\u003c\/li\u003e\n\u003cli\u003eSuited to soil, coco and recirculating hydroponic systems\u003c\/li\u003e\n\u003cli\u003eTwo-window dosing keeps use targeted rather than constant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarly trigger:\u003c\/strong\u003e 1–2ml per litre with every feed for the first 7 days of flower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLate hardening:\u003c\/strong\u003e 1–2ml per litre with every feed during weeks 6–7\u003c\/li\u003e\n\u003cli\u003eIn run-to-waste systems, aim for 20–30% runoff on each feed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003cp\u003e\u003cstrong\u003eFormula type:\u003c\/strong\u003e Flowering stimulant, no published NPK\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication rate:\u003c\/strong\u003e 1–2ml\/L, every feed for 7 days (early), repeated weeks 6–7 (late)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrow phase:\u003c\/strong\u003e Early flower and late ripening\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible systems:\u003c\/strong\u003e Soil, coco, recirculating hydroponics\u003c\/p\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;\"\u003eDiamond Density · soil, coco and recirculating hydroponics\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;\"\u003eEarly trigger, every feed for the first 7 days of flower\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e1–2 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e10–20 ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fcfaf4;\"\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;\"\u003eLate hardening, every feed in weeks 6 and 7\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e1–2 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e10–20 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 — Dosed on top of an existing nutrient programme at two windows only, not continuously.
