Compo Hakaphos Grün 20-5-10 – High-Nitrogen Growth Accelerator for Lush Green Foliage
The foundation of a successful growing season is rapid, vigorous structural development. When your crops need to build leaf mass, strong stems, and healthy root systems, they require a nitrogen-dominant nutrient profile. Compo Hakaphos Grün 20-5-10 is the industry-standard mineral fertilizer engineered for the vegetative stage. Whether you are starting seedlings, maintaining leafy greens, or kickstarting perennials after winter, this nitrogen-rich formulation delivers immediate results. Available in sizes ranging from the 1 kg bag for small-scale projects to the 25 kg sack for large-scale operations.
🌱 When to choose Hakaphos Grün?
This formula serves one primary purpose: Scaling biomass and chlorophyll production. Use it to fuel high-speed growth during the initial stages of your plant's lifecycle.
-
Seedling & Cutting Start: Ideal for young plants establishing their structure after transplanting.
-
Leafy Crops: The perfect choice for heavy-feeding vegetables that require continuous vegetative growth.
-
Spring Regeneration: Use it as a seasonal "wake-up" call for shrubs and perennials that need to recover from the dormant period.
Note: Switch to a bloom-focused formula as soon as the transition to the generative (flowering) phase begins to avoid inhibiting fruit or flower development.
Why high nitrogen matters for your growth phase
Nitrogen is the primary component of chlorophyll, the pigment that allows plants to convert light into energy. With its 20% nitrogen content (20-5-10), Hakaphos Grün acts as a potent engine for foliage development. It is formulated to be highly bioavailable, allowing plants to recover from stunted growth or pale, yellowing leaves in record time.
By prioritizing nitrogen during the early growth stages, you ensure that the plant develops the "solar panel" capacity (leaf area) necessary to support heavy yields later in the season. The result is a compact, vibrant, and structurally sound plant ready to handle the demands of the flowering stage.
Key Benefits for Vegetative Success:
- 🚀 Rapid Growth Kick: High-efficiency nitrate and ammonium sources provide both immediate and sustained nitrogen availability.
- 🍋 Hard Water Compatibility: Contains a specialized acid-buffering complex that keeps the solution stable even when using hard or alkaline tap water.
- 🔬 Fully Chelated Micronutrients: Essential iron, manganese, and zinc are fully protected, ensuring they remain available to the roots rather than locking out in the soil.
Practical Application Guidelines
Hakaphos Grün is a professional-grade concentrate. Because it is highly potent, it is designed for efficient, low-dose application.
Vegetable & Seedling Care
Apply 0.5 to 1.0 gram per liter of water (approx. 5–10 grams per 10 liters). Use once every 1–2 weeks during the active growth phase, adjusting frequency based on crop requirements.
Container & Ornamental Care
For established container plants waking up from winter, use 1.5 to 2.0 grams per liter to encourage robust new canopy growth after pruning.

Frequently Asked Questions (FAQ)
-
Can this be used for lawn care?
Yes. Due to its high nitrogen content, it serves as an excellent liquid spring fertilizer for lawns. It promotes rapid greening and assists in filling in patches after scarifying (20–30g per 10L water per 10m²).
-
Why are leaves still yellowing despite application?
Check your water quality. If leaves remain pale despite fertilization, iron chlorosis caused by high pH/calcified water might be the issue. While Hakaphos Grün includes chelated iron, you may need to monitor your water's pH if using very hard local tap water.
