Green Planet GP3: Grow — 10Ltr

Green Planet GP3: Grow — 10Ltr

GP3: Grow is the vegetative-growth component of Green Planet's flagship 3-part nutrient system — the most precise way to feed plants at every stage. 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.

Why growers choose GP3:

• Maximum ratio control — 3-part system lets you fine-tune NPK at every stage
• Vegetative-growth focus — GP3: Grow delivers the nitrogen-heavy profile veg demands
• Works across all growing media — soil, coco, hydro, rockwool
• Proven Green Planet quality — lab-tested, consistent batch to batch
• Scales from hobby to commercial — 1L through 23L sizing
• Pairs with the full Green Planet additive range — Pro-Cal, Rezin, Bud Booster, Dense

Who it's not for:

GP3: 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.
