Green Planet GP3 Grow

GP3 Grow is the vegetative-phase nutrient base of Green Planet’s professional GP3 3-part system. Formulated to deliver the essential building blocks for rapid growth, it supplies nitrogen, phosphorus, potassium, and a complete suite of chelated micronutrients that fuel strong stems, lush foliage, and resilient root systems. By focusing on the nutrients that matter most during veg, GP3 Grow creates the foundation for healthier, higher-yielding crops in bloom.

With a 2-1-6 NPK ratio, GP3 Grow promotes vigorous leaf development, structural strength, and root vitality. Like the rest of the GP3 line, it is formulated with ultra-clean, fully water-soluble ingredients and contains no synthetic dyes or carbonates. This ensures a low salt/residue profile, preventing build-up in reservoirs and irrigation systems while keeping solutions stable and efficient. Its clean formulation makes it ideal for recirculating hydro setups, coco programs, and soil-based gardens alike.

Micronutrients are fully chelated for maximum bioavailability, and GP3 Grow features three distinct iron sources to ensure steady uptake across a wide pH range. This guarantees plants maintain consistent access to key elements even when conditions fluctuate. When paired with GP3 Micro and GP3 Bloom, growers can fine-tune nutrient ratios to suit cultivar needs, environmental factors, and growth targets.

The result is vigorous, healthy vegetative growth that supports dense branching and robust structures, giving plants the strength and vitality they need to carry heavy flowers later in their cycle.
