Complete Vegetative Nutrition with Grow A + B
Nutri+ Nutrient Grow B is designed to work together with Grow A as a complete two-part nutrient system for vegetative growth.
Grow B provides an NPK analysis of 1-5-8, while Grow A provides 4-0-2. When used together in equal quantities, the two formulas deliver a balanced nutrient profile intended for plants during active vegetative development.
The complete Nutri+ Grow A+B system provides a combination of:
- Nitrogen
- Phosphorus
- Potassium
- Calcium
- Magnesium
- Trace elements
This combination provides primary and secondary nutrients along with micronutrients as part of a complete vegetative feeding program.
Phosphorus & Potassium for Vegetative Development
With its 1-5-8 NPK ratio, Nutri+ Nutrient Grow B provides an important source of phosphorus and potassium within the Grow A+B system.
Phosphorus plays an important role in plant energy transfer and root development, while potassium supports overall plant function, water regulation, and plant strength.
Used together with Grow A, Grow B helps create a balanced nutrient profile for plants developing roots, stems, branches and foliage during the vegetative stage.
Calcium & Magnesium as Part of the Grow System
An important feature of the Nutri+ Grow A+B system is its calcium and magnesium content.
Calcium contributes to healthy root development and plant structure, while magnesium is an essential component of chlorophyll and plays a central role in photosynthesis. The Grow formulation is specifically described as rich in calcium and magnesium.
This makes Grow B an important companion to Grow A rather than a fertilizer designed to be used by itself.
High-Quality Mineral Nutrient Formula
Nutri+ Nutrient Grow B is manufactured using high-quality mineral salts dissolved in reverse-osmosis purified water.
The formula is also produced without chlorine, providing growers with a consistent, concentrated nutrient base for hydroponic and substrate-based growing programs.
Its concentrated formulation lets growers accurately measure small amounts when preparing irrigation or hydroponic nutrient solutions.
Ideal for Hydroponics, Soil, Coco & Soilless Media
Nutri+ Nutrient Grow A+B can be used across several common growing methods, including:
- Hydroponic systems
- Recirculating systems
- Drain-to-waste irrigation
- Potting soils
- Soilless growing media
- Coconut coir
- Container gardening
This versatility allows growers to maintain the same basic two-part vegetative nutrient system across different growing media.
Simple Two-Part A+B Feeding System
Nutri+ Nutrient Grow uses a straightforward two-part A+B feeding program.
The recommended dosage is:
Nutri+ Grow A: 2 ml per litre of water
Nutri+ Grow B: 2 ml per litre of water
Use both components during the vegetative growth period to create the complete nutrient solution.
Because the formulas are highly concentrated, you need only small, measured quantities, making the system practical for both small gardens and larger horticultural applications.
How to Use Nutri+ Nutrient Grow B
Shake Before Use:
Shake the container thoroughly before measuring.
Grow A Application Rate:
Add 2 ml of Nutri+ Nutrient Grow A per litre of water.
Grow B Application Rate:
Add 2 ml of Nutri+ Nutrient Grow B per litre of water.
When to Apply:
Use throughout the vegetative growth period.
Transition to Flowering:
When plants enter the flowering stage, discontinue the Grow A+B formula and switch to the appropriate Nutri+ Bloom Part A & Part B nutrient program.
Important:
Grow A and Grow B are designed to work together. Add each concentrate separately to the water, rather than mixing concentrated Grow A and Grow B directly.
Why Choose Nutri+ Nutrient Grow B?
Nutri+ Nutrient Grow B (1-5-8) is an excellent choice for growers looking for a concentrated mineral fertilizer designed specifically for vegetative plant development.
Combined with Nutri+ Nutrient Grow A (4-0-2), it creates a complete A+B feeding program containing nitrogen, phosphorus, potassium, calcium, magnesium and trace elements to support plants throughout vegetative growth.
Its compatibility with hydroponics, soil, coconut coir and soilless media makes it highly versatile, while the straightforward 2 ml/L Grow A + 2 ml/L Grow B application rate makes nutrient preparation simple and consistent.
