🌱 Royal Dutch Complete Professional Nutrient Soil A and B — Guide and Product Information

Product Overview

Royal Dutch Complete Professional Nutrient Soil A and B is a complete two-part base nutrient developed for fast growing plants cultivated in soil. Designed to support strong overall plant performance, this formulation is intended for growers looking for a reliable soil nutrient programme that promotes healthy development and productive growth.

As a dedicated soil nutrient, this A and B combination is suited to growers who want a straightforward feeding base for soil-based cultivation, whether in pots, containers or indoor grow spaces using quality compost or soil mixes.

Key Benefits for Soil Growing

This nutrient has been specifically developed for use in soil, where balanced feeding is important for steady root zone performance and strong above-ground growth. Used correctly, a two-part nutrient helps maintain a more controlled nutrient profile than one-part feeds, giving growers flexibility and consistency across different stages of growth.

• ✔ Developed specifically for soil cultivation
• ✔ Complete A and B nutrient system for routine feeding
• ✔ Supports superior plant growth in soil-based setups
• ✔ Suitable for growers aiming to improve overall crop performance

📦 Available Options and Sizes

Royal Dutch Complete Professional Nutrient Soil A and B is available in three size options, making it suitable for hobby growers and larger cultivation spaces alike.

• ✔ 1L
• ✔ 5L
• ✔ 10L

The 1L option is ideal for smaller grows, trial use or growers with only a few plants. The 5L size suits regular grow room use, while the 10L option is practical for larger setups or growers who prefer to keep a larger feeding stock on hand.

Suitable Applications

This product is intended for plants grown in soil and soil-based media. It can be used in hand-watered pots, indoor grow tents, greenhouse containers and similar soil cultivation setups where a dedicated base nutrient is required.

Setup and Usage Tips

Always use Soil A and Soil B as directed and avoid mixing the concentrates together in their undiluted form. Add each part separately to water and mix thoroughly before application. Start with a cautious feeding approach if you are working with lightly fed plants, young plants or nutrient-rich soil.

Check the condition of your plants regularly and adjust feeding strength according to plant stage, media condition and watering frequency. In soil systems, allowing a sensible wet and dry cycle can also help support healthy root performance. Keep your grow room environment stable, as lighting, temperature and airflow all influence how effectively plants use nutrients.
