{"product_id":"biotabs-pk-5-8","title":"BioTabs PK 5-8","description":"\u003ch2\u003eAn organic top-booster built for the last stretch of flower\u003c\/h2\u003e\u003cp\u003eBioTabs PK 5-8 is an organic liquid flowering accelerator with an NPK of 2-5-8, formulated around seaweed, vitamins A, B1, B2, B3 and B12, auxins and other phytohormones, plus calcium, molasses and humic acid. It's dosed from the second week of flowering right through to a week before harvest, at 1-3ml per litre with every watering, or as a heavier weekly feed of 10ml per plant, diluted in at least a litre of water, across weeks 3 to 6 of bloom.\u003c\/p\u003e\u003cp\u003eIt's built for soil and coco growers running potted or in-ground plants, and — like most organic liquid feeds with a bit of body to them — BioTabs specifically advise against running it through drip irrigation or AutoPot-style systems, since it can block fine pipework; hand watering is the recommended route, with automated watering systems switched off for 24 hours either side of application. That makes it a good fit for hand-fed soil or coco grows looking for an organic route to bigger, denser, more fragrant flowers without reaching for a synthetic PK booster.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurpose-built for late flower\u003c\/strong\u003e — dosed from week two of bloom through to a week before harvest.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoaded with bloom-support extras\u003c\/strong\u003e — seaweed, vitamins A\/B1\/B2\/B3\/B12, auxins and phytohormones alongside the core NPK.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrganic route to bigger buds\u003c\/strong\u003e — phosphorus, potassium and calcium aimed at flower size, density and fragrance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo dosing options\u003c\/strong\u003e — a steady 1-3ml\/L every watering, or a heavier 10ml-per-plant feed across weeks 3-6.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuits soil and coco\u003c\/strong\u003e — for potted or in-ground plants, hand-watered rather than fed through driplines.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eNPK: 2-5-8 + calcium (2.5%), seaweed, molasses, humic acid, vitamins A\/B1\/B2\/B3\/B12\u003c\/li\u003e\n\u003cli\u003eDose: 1-3ml per litre every watering (week 2 of flower to 1 week pre-harvest), or 10ml per plant in at least 1L water (weeks 3-6)\u003c\/li\u003e\n\u003cli\u003eApplication: hand watering only — not recommended through drip or AutoPot systems\u003c\/li\u003e\n\u003cli\u003eGrowing medium: soil, coco — potted or in-ground\u003c\/li\u003e\n\u003c\/ul\u003e\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;\"\u003eBioTabs PK 5-8 · soil and coco, hand watered\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;\"\u003eWeek 2 of flower to a week before harvest, every watering\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;font-weight:600;\"\u003e1–3 ml\u003c\/td\u003e\n\u003ctd style=\"padding:12px 20px;border-top:1px solid #ededed;text-align:right;white-space:nowrap;color:#6b6b6b;\"\u003e10–30 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 — BioTabs also publish a heavier alternative measured per plant rather than per litre: 10 ml per plant, diluted in at least a litre of water, once a week across flowering weeks 3 to 6.
