It's a properly formulated 14:15 ratio with added iron and micronutrients — not just a quick phosphorus dump. Run it for a short window mid-flower, keep it measured, and it'll support bud weight and firmness without turning your feeds harsh. One we recommend regularly for growers who want results without guessing.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eIonic PK Boost is a \u003cstrong\u003econcentrated phosphorus and potassium flowering additive\u003c\/strong\u003e designed to support heavier yields and stronger bud development during the final weeks before harvest. Manufactured by Growth Technology Ltd, it delivers a balanced 14:15 PK ratio alongside iron and micronutrients — the kind of thinking you don't always get in a simple booster. Use it as a targeted push in mid to late flower, not as an everyday bottle, and it'll work across soil, coco, and hydroponics without fuss.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eIonic PK Boost sits firmly in the \u003cstrong\u003epremium formulated booster\u003c\/strong\u003e category.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBalanced 14:15 ratio with added iron and micronutrients — more evolved than basic PK products\u003c\/li\u003e\n\u003cli\u003eHigher concentration than earlier Ionic formulas, so you dose weekly rather than every watering\u003c\/li\u003e\n\u003cli\u003eDesigned to avoid mineral accumulation in reservoirs, which matters if you're running hydro or recycling water\u003c\/li\u003e\n\u003cli\u003eSignificantly more affordable than branded premium alternatives without cutting corners on formulation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn simple terms: proper booster thinking at a sensible price.\u003c\/p\u003e\n\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSoil and coco growers (hand-fed)\u003c\/strong\u003e\u003cbr\u003e\nAdd 1ml per litre of feed water once per week during mid to late flowering. Make up your base feed first using Ionic Bloom or any decent quality bloom nutrient, then add the PK Boost and stir in properly. Aim for an EC of 1.5 (CF 15). Adjust pH if needed.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHydroponic growers\u003c\/strong\u003e\u003cbr\u003e\nMix your base nutrient as normal, then add Ionic PK Boost at 1ml per litre. Bring your EC up to 2.0 (CF 20). Change your reservoir weekly — this is when PK boosters work best.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhen to start and stop\u003c\/strong\u003e\u003cbr\u003e\nIntroduce Ionic PK Boost around mid-flower when bud set is underway. Run it for 3-4 weeks, then drop it in the final week before harvest. Don't extend it or increase dosage — this is a short, sharp tool, not an everyday bottle.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCritical point\u003c\/strong\u003e\u003cbr\u003e\nNever use Ionic PK Boost alongside other PK boosters, and never exceed the recommended rate. Overdoing phosphorus and potassium causes nutrient lockout and salt buildup faster than almost anything else. Sensible dosing works. Hammering it doesn't.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMixing note\u003c\/strong\u003e\u003cbr\u003e\nNever mix nutrients together in concentrate form. Add each one to your water in turn, stir properly, then add the next. This applies especially to boosters — they need space in solution to break down properly.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNPK Ratio:\u003c\/strong\u003e PK 14:15 (14% phosphorus, 15% potassium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional nutrients:\u003c\/strong\u003e Extra iron and micronutrients for enhanced firmness and flower density\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage rate:\u003c\/strong\u003e 1ml per litre of feed water (weekly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget EC soil\/coco:\u003c\/strong\u003e 1.5 (CF 15)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget EC hydroponics:\u003c\/strong\u003e 2.0 (CF 20)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable sizes:\u003c\/strong\u003e 300ml, 1 litre, 5 litres, 20 litres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentration:\u003c\/strong\u003e Highly concentrated — higher than previous Ionic Boost formula\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Works with soil, coco, and all hydroponic systems; use only with bloom-range base nutrients\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Growth Technology Ltd (UK-based)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMid-level growers running soil, coco, or hydro who want to push yields without complexity\u003c\/li\u003e\n\u003cli\u003eGrowers already using Ionic base nutrients (Bloom, Grow) who want a matched booster that actually works with the system\u003c\/li\u003e\n\u003cli\u003eAnyone running hand-fed setups where a weekly dose schedule fits naturally into feeding routine\u003c\/li\u003e\n\u003cli\u003eHydroponic growers wanting to maximise bud weight and density without mineral salt accumulation\u003c\/li\u003e\n\u003cli\u003eGrowers who've tried other PK boosters and found them too aggressive or chemically simple\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly well suited to anyone who values \u003cstrong\u003ereliable, measured results\u003c\/strong\u003e over flashy promises.

It's properly formulated, it's made in the UK by a company that actually understands nutrient chemistry, and it sits at a price point that makes sense for everyday growers. The 14:15 ratio with added iron and micronutrients means you're getting genuine thought in the bottle, not just phosphorus and potassium thrown together.\u003c\/p\u003e\n\n\u003cp\u003eUse it right — measured doses for a short window mid-flower — and you'll see measurable improvements in bud weight and firmness. Misuse it, and you'll learn some expensive lessons about nutrient lockout. The difference is respect for the tool and your plants.\u003c\/p\u003e\n\n\u003cp\u003eIf you're running Ionic base nutrients or looking for a booster that works across multiple systems without faffing about, worth picking up while stock lasts. Does exactly what it should, week in, week out.\u003c\/p\u003e\n\n\u003c\/section\u003e\n```","brand":"IONIC","offers":[{"title":"1 Litre","offer_id":47916579258538,"sku":"89107","price":14.99,"currency_code":"GBP","in_stock":false},{"title":"5 Litre","offer_id":47916579291306,"sku":"89109","price":54.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/89107_-_1_litre_1_5017285b-61c6-4efb-aba8-bbe12514481f.jpg?v=1769196535","url":"https:\/\/growershouse.co.uk\/products\/ionic-pk-boost-pk-1415-1-litre-m25916","provider":"Growers House ","version":"1.0","type":"link"}
