DutchPro Soil Grow A/B is a professional, two-part base fertilizer for plants in the growth phase, specially formulated for soil-based cultivation. The system consists of two parts— Grow A and Grow B —which, when used together, provide plants with a comprehensive set of essential macro- and micronutrients.
The Soil Grow A/B formula is designed to promote intensive vegetative growth. The carefully balanced nutrients support the development of roots, leaves, stems, and new shoots, preparing the plant for the next stages of its life cycle.
DutchPro Soil Grow A/B can serve as the foundation of a fertilization program throughout the entire growth phase. This fertilizer is intended for use in soil-based growing media and can be combined with appropriate DutchPro additives.
The vegetative growth phase is crucial for the plant’s subsequent development. It is during this phase that the root system develops intensively, the leaf area increases, and new shoots and stems form.
DutchPro Soil Grow A/B provides the carefully selected nutrients needed for these processes to proceed properly. The formula is based on a set of essential elements that support metabolism, photosynthesis, and the formation of new plant tissues.
Dividing the fertilizer into two parts helps maintain high nutrient concentrations and their stability during storage. Certain mineral compounds in highly concentrated forms can react with one another, which is why they have been separated between Soil Grow A and Soil Grow B.
Both parts are essential and should be used in equal amounts.
Important: Do not mix concentrate A directly with concentrate B. First, add part A to the water, mix thoroughly, and then add part B.
Both components should be used in equal amounts. The exact dosage should be adjusted according to the plant’s stage of development, water quality, and target EC value.
| ComponentDosage MethodApplication | |||
|---|---|---|---|
| Soil Grow A | Same amount as Part B – adjust dosage to EC | Growth phase |
| Soil Grow B | Same amount as Part A – adjust dosage to EC | Growth phase |
In practice, the dosage should be increased gradually as the plants develop, while monitoring the EC of the prepared nutrient solution. DutchPro recommends that A and B always be used in equal proportions.
Preparing the nutrient solution is simple, but the correct order of adding the ingredients is very important:
Do not pour Concentrate A directly into Concentrate B. Both parts should be diluted in water separately.
The DutchPro Soil Grow A/B formula was developed specifically for soil-based growing media. Choosing the right base fertilizer for the type of growing medium is important because soil, coconut coir, and hydroponic systems differ in how they store and release minerals to plants.
Therefore, the Soil version should be used for soil-based cultivation, while the DutchPro Hydro/Coco line is designed for coconut coir and hydroponics.
DutchPro Soil Grow A/B is designed for the vegetative growth stage. When a plant enters the flowering phase, its nutrient requirements change.
At that point, the Grow fertilizer is replaced with the appropriate DutchPro Soil Bloom A/B formula, whose nutrient ratios have been adjusted to meet the plants’ needs during flowering.
