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","brand":"IONIC","offers":[{"title":"1 Litre","offer_id":47916579258538,"sku":"89107","price":14.99,"currency_code":"GBP","in_stock":true},{"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\/collections\/ionic-nutrients.oembed","provider":"Growers House ","version":"1.0","type":"link"}
