Why You Need House & Garden Coco A&B
Coco coir is an excellent growing medium — but it naturally binds certain nutrients, especially calcium and magnesium. House & Garden Coco A&B is specially formulated to overcome this challenge by supplying a precise balance of macro and micronutrients tailored for coco-based cultivation. This ensures your plants get exactly what they need at every stage of growth, preventing deficiencies and promoting vigorous, even development.
With its highly refined composition, this formula supports consistent nutrient uptake, leading to strong roots, thick stems, and heavy yields. Whether you’re a first-time coco grower or managing a large-scale setup, Coco A&B delivers proven Dutch performance you can rely on.
How House & Garden Coco A&B Works
This two-part nutrient system provides a complete nutritional foundation for your plants. Part A delivers nitrogen, calcium, and essential trace elements that fuel vegetative growth and structural integrity, while Part B contains phosphorus, potassium, and other flowering essentials that promote dense buds and healthy fruit formation.
Together, these nutrients form a balanced, pH-stable solution that ensures optimal nutrient availability and absorption across all growth stages. The formulation also includes chelated micronutrients, which improve stability and efficiency under varying pH levels — keeping your plants well-fed and resilient from start to finish.
How to Use House & Garden Coco A&B
- Prepare your water: Fill your reservoir or mixing container with clean, filtered water.
- Add Coco A & B: Add equal parts of Part A and Part B one at a time, stirring thoroughly between each addition. Never mix concentrates together undiluted.
- Check strength: Use an EC or PPM meter (such as the Bluelab Truncheon) to ensure nutrient strength is within the target range of 1.2–2.0 EC.
- Adjust pH: Use a reliable pH meter (like the Essentials pH Meter) to set your solution to pH 5.5–6.2 (optimum 5.8).
- Add boosters: Mix in any other House & Garden additives (e.g. Roots Excelurator, Multi Zyme, or Bud-XL), stirring between each one.
- Feed your plants: Use as part of your regular feeding schedule from rooted cutting through to late flower.
