BAC Coco Grow A/B 2 x 1l
BAC Coco Grow A/B 2x1 litre is a highly concentrated two-component mineral base nutrient system designed for the vegetative growth phase on coco substrates. The A&B format separates calcium and phosphorus into two bottles dosed in equal parts, ensuring maximum nutrient stability and bioavailability in inert coco media. Featuring premium red chelate iron across both components, this formula delivers complete macro and micronutrient coverage at a dosing rate of 25–35 ml total per 10 litres at EC 1.6. Compatible with coco slabs and coco pots. Engineered by Dutch specialist BAC for precision coco cultivation. Experience the A&B advantage in your coco grow.
BAC Coco Grow A/B 2x1 litre – two-component mineral growth nutrition for coco
Coco substrates demand nutrient delivery systems engineered for inert media, and BAC Coco Grow A/B is purpose-built for that requirement. This two-component mineral formula from BAC separates chemically incompatible elements into component A (NPK 12-0-1) and component B (NPK 4-3-4), ensuring complete solubility and immediate root availability when dosed in equal parts. Featuring red chelate iron for superior trace element bioavailability on coco, this concentrated system provides everything needed for robust vegetative development on slabs and coco pots.
Understanding the A&B two-component system
The A&B architecture addresses a fundamental chemistry challenge in concentrated nutrient formulation. Calcium (concentrated in component A) and phosphorus (concentrated in component B) form insoluble precipitates when combined at high concentrations. By maintaining separation until dilution in the irrigation water, BAC ensures that every element remains plant-available in solution. This is non-negotiable for coco cultivation, where the substrate provides zero natural buffering capacity unlike soil. The practical implication for growers is maximum nutrient efficiency and zero waste from precipitation in the mixing tank.
- Component A (NPK 12-0-1): high nitrogen with calcium for cell wall construction and vigorous vegetative growth.
- Component B (NPK 4-3-4): phosphorus, potassium, and magnesium for energy metabolism and root architecture development.
- Equal-parts dosing: always add A first to water, mix thoroughly, then add B. Never combine concentrates directly.
Dosing protocol for coco substrates
Apply 25 to 35 ml total per 10 litres of water (equal parts A and B), targeting an EC of 1.6. Always add component A to the water first, mix completely, then add component B. Administer with every irrigation throughout the vegetative phase. On coco, maintain a pH between 5.5 and 6.5 for optimal nutrient uptake — this narrower pH window compared to soil makes calibrated monitoring equipment essential. To accelerate root establishment in the critical early weeks, pair this base nutrient with the BAC Root Stimulator for enhanced root mass development in the inert coco medium.
Red chelate iron in coco cultivation
BAC's exclusive use of red chelate iron is particularly advantageous in coco systems. Coco substrates are prone to more frequent pH fluctuations than soil, which can rapidly reduce the bioavailability of standard green DTPA iron chelates. Red chelate iron maintains its molecular stability across a wider pH spectrum, ensuring that trace elements remain consistently accessible to roots even when conditions shift between irrigations. When plants transition to flowering, switch to BAC Coco Bloom A/B for a PK-optimised bloom formula within the same two-component system. During peak bloom, the BAC F1 Extreme Booster adds concentrated phosphorus and potassium to maximise flower density and yield.

How do I dose BAC Coco Grow A/B correctly?
Use equal parts of component A and component B, totalling 25 to 35 ml per 10 litres of water. Always add A to the water first, mix thoroughly, then add B. Never combine the concentrates directly — this would cause precipitation. Target an EC of 1.6 and verify with a calibrated EC meter at every feed.
Why does BAC use an A&B system for coco instead of 1-component?
Coco is an inert substrate with no natural buffering capacity. The A&B system keeps calcium and phosphorus separated in concentrated form to prevent precipitation. Soil naturally buffers these elements, allowing a stable single-bottle formulation. The two-component approach ensures 100% nutrient availability in coco's challenging chemical environment.
What pH range should I maintain with BAC Coco Grow A/B?
For coco substrates, maintain a pH between 5.5 and 6.5 after mixing both components in your irrigation water. This range ensures optimal nutrient availability in inert coco media. Check pH at every feed using a calibrated pH meter and adjust with pH correction products as needed.
Can I use BAC Coco Grow A/B on soil or hydro systems?
BAC Coco Grow A/B is formulated specifically for coco substrates. For soil cultivation, BAC offers a 1-component Soil Grow formula, and for hydroponic systems, a dedicated Hydro Grow A/B. Each product is engineered for the specific buffering and nutrient delivery characteristics of its target substrate to ensure optimal plant performance.
