Green Planet GP3 Grow | 3-Part Hydroponic Base Nutrient | 1L, 5L, 20L

Feed Your Plants the Best — Green Planet GP3 Grow

Give your plants the foundation they need to explode into lush, vigorous growth. Green Planet GP3 Grow is the vegetative-stage component of the industry-leading GP3 3-part nutrient system — trusted by hydroponic growers across Australia for delivering consistent, high-quality results.

Why GP3 Grow?

• ✅ Complete vegetative nutrition — delivers all primary, secondary, and micronutrients your plants need during the grow phase
• ✅ No synthetic dyes — only ethically sourced, premium-grade ingredients
• ✅ Nitrogen-rich formula — fuels photosynthesis, chlorophyll production, and explosive leafy growth
• ✅ Soluble potash (K2O) — strengthens disease resistance and primes plants for a seamless transition to bloom
• ✅ Builds a powerhouse root system — sets the stage for heavy flowering sites in the bloom stage

How It Works

During the vegetative stage, your plants are building the structure they'll rely on for the rest of their life cycle. GP3 Grow delivers the precise nitrogen and potassium ratios needed to develop dense, green foliage and a robust root network — so when bloom time comes, your plants are ready to perform.

Used as part of the complete GP3 system (Grow + Micro + Bloom), your plants receive a perfectly balanced diet of macro, micro, and secondary nutrients at every stage of growth.

How to Use

• Mix 3mL per 1L of water
• Always add each GP3 component separately into your reservoir — never combine undiluted
• Check and adjust PPM and pH after mixing
• Follow the GP3 Feed Program for stage-by-stage application rates

⚠️ Caution: Combining GP3 components in undiluted form may cause nutrient lockout. Always dilute individually into your reservoir.
