Floragard Plug & Germination Soil Mix

Floragard Plug & Germination Soil Mix is a professional-grade soilless cultivation medium engineered for the propagation of vegetable and ornamental seedlings. Formulated as Sakata Plug & Germination (PG), recipe 119845, this substrate meets the stringent quality parameters established by the German Gütegemeinschaft Substrate für Pflanzenbau e.V. (German Quality Assurance Association for Growing Media). The composition is optimized to provide a stable physical structure and a precisely balanced nutrient charge that supports uniform germination and vigorous early root development in plug trays and propagation systems.

Core Constituents and Functional Properties
Each component in the mix serves a specific structural or nutritional purpose, creating an integrated environment for seedling success. The primary constituent is slightly decomposed raised-bog peat, known as white peat. This material provides high air capacity and structural stability, ensuring adequate oxygen reaches developing roots. The inclusion of expanded perlite further increases the total pore volume and enhances air capacity, promoting a well-aerated root zone that resists compaction. To precisely manage the chemical environment, calcium carbonate (lime) is added to adjust and stabilize the pH value to meet the specific requirements of the target plant species.

Integrated Nutrient System for Propagation
The substrate incorporates a multi-stage nutrient supply designed to support seedlings from germination through the initial growth phase. A top-quality compound fertilizer provides an immediate supply of all essential macro and micronutrients upon first watering. This is supplemented by a dedicated micronutrient fertilizer that delivers key elements: magnesium (Mg), boron (B), copper (Cu), manganese (Mn), molybdenum (Mo), iron (Fe), and zinc (Zn). A critical component is a slow-release nitrogenous fertilizer, which provides a sustained, controlled supply of nitrogen over time, preventing nutrient leaching and ensuring consistent growth without the risk of salt burn from excessive soluble salts.

Handling and Application Specifications
A high-performance wetting agent, Instant Plus, is integrated into the formulation. This agent dramatically improves the water uptake of the substrate, particularly when the material is dry, ensuring rapid and uniform initial saturation—a critical factor for consistent seed germination. For optimal performance, the product must be stored in a dry, cool place and protected from direct sunlight. While it is advised to use the product promptly, if stored for an extended period, a pre-use analysis is recommended to verify nutrient status and pH. The substrate is available in two primary formats: a standard Plug & Germination mix and a variant with additional perlite for even greater aeration and drainage. Both are supplied in commercial volumes of 3.8 cubic feet and large-scale 110 cubic feet units.
