BAC Coco Bloom A/B 2 x 1l

BAC Coco Bloom A/B 2x1 litre is a concentrated two-component mineral bloom nutrient engineered for the flowering phase on coco substrates. Component A (NPK 10-0-2) and component B (NPK 3-2-3) are dosed in equal parts, maintaining chemical separation of calcium and phosphorus for maximum nutrient stability in solution. Featuring premium red chelate iron for reliable trace element uptake on coco, this undiluted formula delivers complete bloom nutrition at 30–50 ml total per 10 litres with progressive EC targeting from 1.8 to 2.2. Compatible with coco slabs and pots. The direct successor to BAC Coco Grow A/B in the BAC feeding schedule. Power your coco bloom with proven Dutch formulation.

BAC Coco Bloom A/B 2x1 litre – two-component mineral bloom nutrition for coco

Flowering on coco substrates requires bloom nutrition that accounts for the unique chemical dynamics of inert media. BAC Coco Bloom A/B delivers precisely that: a concentrated two-component mineral formula with component A (NPK 10-0-2) and component B (NPK 3-2-3), manufactured by BAC in the Netherlands. The A&B architecture ensures that calcium and phosphorus remain fully soluble until dilution, while red chelate iron provides trace element stability across the wider pH fluctuations characteristic of coco cultivation.

NPK profile optimised for generative coco cultivation

The bloom-phase NPK profile of BAC Coco Bloom A/B is specifically calibrated for the generative demands of flowering plants on inert coco substrates. Component A maintains a substantial nitrogen and calcium supply to keep the canopy photosynthetically active throughout bloom — an approach that differs from formulas that strip nitrogen during flowering. Component B concentrates the phosphorus, potassium, and magnesium that drive flower formation, cell expansion, and fruit maturation. Together, the two components deliver a balanced nutritional package that supports both flower quality and overall plant health simultaneously.

  • Component A (NPK 10-0-2): nitrogen and calcium for sustained canopy health and photosynthetic capacity during bloom.
  • Component B (NPK 3-2-3): phosphorus, potassium, and magnesium for flower development and maturation.
  • Red chelate iron: premium trace element form maintaining bioavailability across coco's typical pH range of 5.5–6.5.

Progressive EC management on coco

Dose BAC Coco Bloom A/B at 30 to 50 ml total per 10 litres (equal parts A and B), with EC targeting that ramps from 1.8 in early bloom to 2.2 during peak flowering. Always add component A to water first, mix completely, then add component B. On coco substrates, maintain pH between 5.5 and 6.5 for optimal nutrient availability. The progressive EC approach ensures plants receive appropriately scaled nutrition at every flowering stage, preventing both underfeeding during critical flower set and excessive salt accumulation from early overfeeding.

Building the complete BAC coco bloom stack

BAC Coco Bloom A/B is the flowering-phase anchor of a complete BAC coco programme. It follows directly from BAC Coco Grow A/B in the vegetative phase, maintaining A&B system consistency throughout the grow cycle. During peak bloom, integrate the BAC F1 Extreme Booster for supplemental PK delivery that pushes flower density and mass. To refine flower quality and stimulate additional bloom sites, the BAC Bloom Stimulator works synergistically with the base A&B nutrition. All BAC mineral products are Vegan certified and formulated without dilution for maximum nutrient density per millilitre.

What is the dosing rate for BAC Coco Bloom A/B?

Dose 30 to 50 ml total per 10 litres of water using equal parts component A and component B. Start at 30 ml in early bloom and increase progressively toward 50 ml during peak flowering. Target EC ranges from 1.8 to 2.2 depending on the bloom stage. Always add A first, mix, then add B.

How does BAC Coco Bloom A/B differ from BAC Coco Grow A/B?

Both products use the same A&B two-component system, but the NPK ratios differ. Coco Grow A/B (A: NPK 12-0-1, B: NPK 4-3-4) is nitrogen-heavy for vegetative development. Coco Bloom A/B (A: NPK 10-0-2, B: NPK 3-2-3) shifts the balance toward phosphorus and potassium for flowering. The dosing protocol is identical.

Can I use BAC Coco Bloom A/B with nutrients from other brands?

BAC Coco Bloom A/B is designed as a complete base nutrient and works optimally within the BAC product ecosystem. While the F1 Extreme Booster is compatible with any nutrient brand, for best results with the base A&B nutrition, BAC recommends staying within the BAC mineral line to ensure formulation synergy and consistent results.

What happens if I mix components A and B without diluting first?

Mixing concentrates A and B directly causes calcium-phosphate precipitation — the formation of insoluble particles that lock nutrients out of solution. This renders essential elements unavailable to your plants. Always dilute component A in water first, mix thoroughly, then add component B to the already-diluted solution.
