The 3-part format (Grow, Bloom, Micro) gives you full control over NPK ratios: heavy on Grow during veg, shift toward Bloom in flower, with Micro providing the essential trace elements throughout. Works across all media — soil, coco, hydro, rockwool. Available from 1L home bottles to 23L commercial drums.\u003c\/p\u003e\n\n\u003ch3\u003eWhy growers choose GP3:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum ratio control\u003c\/strong\u003e — 3-part system lets you fine-tune NPK at every stage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVegetative-growth focus\u003c\/strong\u003e — GP3: Grow delivers the nitrogen-heavy profile veg demands\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWorks across all growing media\u003c\/strong\u003e — soil, coco, hydro, rockwool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProven Green Planet quality\u003c\/strong\u003e — lab-tested, consistent batch to batch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScales from hobby to commercial\u003c\/strong\u003e — 1L through 23L sizing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePairs with the full Green Planet additive range\u003c\/strong\u003e — Pro-Cal, Rezin, Bud Booster, Dense\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWho it's not for:\u003c\/h3\u003e\n\u003cp\u003eGP3: Grow must be used alongside GP3: Bloom and GP3: Micro — it's one-third of a complete system, not a standalone nutrient. If three bottles feels like too much complexity, Green Planet's Medi-One is a simpler 1-part alternative, or Dual Fuel offers a 2-part middle ground. Never mix concentrated GP3 parts together before diluting; always add each to your reservoir separately. For hydro-specific formulation, the Hydro Fuel range is specifically tuned for recirculating systems.\u003c\/p\u003e\n\n\u003cp\u003eIn stock now — ships same working day from our Staffordshire warehouse with free UK delivery over £100.
