Atami B'cuzz Bio Growmix - Lightly pre-fertilized substrate for an explosive start

Atami Bio Growmix is a premium, lightly pre-fertilized organic substrate from the B'cuzz line, designed for growers who want full control over their plants’ nutrition from the very start. It provides ideal conditions for rooting seedlings and cuttings and ensures they have enough nutrients for the first, most critical week of life.

Key features and benefits of Atami Bio Growmix

• Light pre-fertilization: Essential nutrients for the first week give plants a strong start and give you full control over further fertilization.
• Airy and light structure: Ensures an optimal air-to-water ratio, promoting vigorous root development and preventing waterlogging.
• Contains worm castings: A natural ingredient rich in microorganisms and nutrients that improves plant vitality and their ability to absorb nutrients.
• Stable pH and low EC: Predictable pH values (5.5–6.5) and low EC (1.25–1.50) provide the perfect foundation for your own fertilization plans.
• RHP quality certification: A guarantee that the substrate is clean, free of pests, pathogens, and impurities, and meets the strictest quality standards.

Detailed Composition and Structure

The foundation of Bio Growmix is a carefully selected blend of the highest-quality peat types. This combination ensures the substrate’s lightness and ability to retain sufficient moisture without causing unwanted waterlogging.

The key component is earthworm humus (vermicompost), which enriches the substrate with beneficial microorganisms and naturally available nutrients. Thanks to this unique structure, an ideal air-to-water ratio is ensured, which is essential for the healthy and rapid development of strong roots—the foundation of a thriving plant.

Nutrient Profile and Fertilization Recommendations

Bio Growmix is intentionally only lightly pre-fertilized to provide you with maximum flexibility. An initial dose of fertilizer with an NPK ratio of 12-14-24 will cover all the plant’s nutritional needs for approximately the first week of growth. After this period, you can begin your own fertilization program tailored precisely to the needs of your specific variety and stage of development.

The low EC value (1.25–1.50) confirms that the substrate is not over-fertilized, giving you confidence when applying additional fertilizers. A stable pH in the range of 5.5–6.5 ensures optimal availability of all nutrients to the plant roots.

RHP Guarantee of Highest Quality

Atami Bio Growmix boasts the prestigious RHP (Regeling Handels Potgronden) certification. This quality certificate guarantees growers that the substrate has undergone rigorous testing and is completely safe. It guarantees the absence of heavy metals, pathogens, weed seeds, and other contaminants.

With the RHP certification, you can be sure that you are investing in a clean and consistent growing medium that will give your plants the best possible start.

Ideal Use

This substrate is the perfect choice for germinating seeds and rooting cuttings. It is ideal for all growers who want to control the nutrient regimen themselves from the start and tailor it to the specific needs of their plants.

It is great for growing a wide range of annuals, herbs, chili peppers, tomatoes, and other fruiting vegetables, where precise control over nutrients is key to a bountiful and high-quality harvest.
