A+B Grow and A+B Bloom Soil Hard Water – Complete Base Nutrients for Soil

Complete base nutrition for optimal plant development!

A+B Grow and A+B Bloom Soil Hard Water provide a complete base nutrient solution specifically formulated for soil cultivation. Their two-part system supplies the essential macro and micronutrients plants need during vegetative growth and flowering.

With two specialised formulas, growers can adapt feeding to each stage of plant development: A+B Grow provides base nutrition for vegetative growth, while A+B Bloom is designed to meet the nutritional requirements of the flowering stage.

Their formulation is based on Liebig's Law of the Minimum, which states that plant development can be limited by the essential nutrient available in the shortest supply relative to the plant's requirements. These formulas therefore include all 17 essential elements to provide complete and balanced nutrition.

They are also specifically developed for use with hard water, making them suitable for water with a relatively high mineral content.

A+B Grow Soil Hard Water – Vegetative Growth

A+B Grow Soil is formulated to support the vegetative development of plants grown in soil.

Its NPK composition of 3-2-5 provides a nutrient profile adapted to this stage, supplying nutrients to support root, stem and leaf development and balanced plant growth.

Important: use Grow base nutrients only during the vegetative growth phase.

A+B Grow Dosage

Add the indicated amounts of components A and B per litre of water:

The final EC will depend on the source water and the prepared nutrient solution. Monitor electrical conductivity and adjust dosage according to the crop's requirements.

A+B Bloom Soil Hard Water – Flowering

A+B Bloom Soil is designed to provide base nutrition adapted to plant requirements during flowering.

Its NPK composition of 4-1-6 provides a nutrient profile suited to this stage, supplying essential macro and micronutrients to support flower development and balanced plant nutrition.

Important: use Bloom base nutrients only during the flowering phase.

A+B Bloom Dosage

Add the indicated amount of each component, A and B, per litre of water:

The feeding schedule covers flowering weeks 1, 2, 3, 4, 5, 6, 7 and onwards. Concentration should be adjusted according to plant development, source water quality and crop nutritional requirements.

Complete Nutrition for Soil Cultivation and Hard Water

A+B Grow and A+B Bloom Soil have been specifically developed for soil cultivation, taking into account the nutritional requirements of plants throughout their different stages of development.

Their two-part system allows growers to prepare a complete nutrient solution and adjust feeding according to the growing stage. The hard water formulation is designed for use with water that has a relatively high mineral content.

The inclusion of 17 essential elements helps provide the nutrients required for balanced plant nutrition. The availability of each element will also depend on growing medium characteristics, pH and cultivation conditions.

Frequently Asked Questions

What is the difference between A+B Grow Soil and A+B Bloom Soil?

Grow is formulated for the vegetative growth phase, while Bloom is intended for flowering. Each product has a specific NPK composition: 3-2-5 for Grow and 4-1-6 for Bloom.

Are these nutrients designed for hydroponics or coco?

No. This Soil version is specifically formulated for soil cultivation. For hydroponic systems and coco growing media, use the dedicated Hydro/Coco range.

What does hard water formulation mean?

It means the formulas are designed to work with water that contains a relatively high concentration of dissolved minerals.

How much nutrient should I add per litre?

The stated dosage range is 2.5–5 ml per litre. For Bloom, this amount applies to each component, A and B. Monitor the final EC and follow the manufacturer's instructions.

What EC should I maintain?

The recommended ranges are 1.5–2.0 for Grow and 1.8–2.3 for Bloom. The appropriate EC will depend on source water, growing medium and plant requirements.

What are the 17 essential elements?

They are the mineral and non-mineral elements plants need to complete their life cycle. Their balanced availability is fundamental to plant development.

Which sizes are available?

Both A+B Grow Soil and A+B Bloom Soil are available in 1, 5, 10 and 20-litre containers.
