Atami ATA Coco Max A&B 1L is a professional two-part mineral base nutrient developed specifically for plants grown in coco and coco-based substrates. Used throughout growth and flowering, it provides balanced primary nutrition together with calcium and essential trace elements for consistent crop development.

Coco combines excellent water retention with an open, oxygen-rich root structure, but its nutritional behaviour differs significantly from conventional soil and peat-based growing media. ATA Coco Max is formulated specifically around these characteristics rather than being a general-purpose fertiliser adapted for coco.

The nutrient is supplied as two complementary concentrates. Coco Max A has an NK analysis of 4-0-1 W/W and contains calcium, while Coco Max B has an NPK analysis of 1-4-5 W/W. Together they provide the balanced mineral nutrition required by coco-grown plants.

ATA Coco Max is designed for use throughout the crop cycle, allowing growers to use the same A&B base nutrient through vegetative development, flowering and ripening rather than changing between separate grow and bloom base feeds.

The general application rate is 1-4ml/L of Coco Max A plus 1-4ml/L of Coco Max B. This 1L set contains 1L of Part A and 1L of Part B, providing 2L of concentrate in total.

Base nutrition formulated specifically for coco

Coco coir is widely used as a professional growing medium because it combines strong water-holding capacity with a naturally airy structure around the root system.

Its chemical behaviour, however, differs from conventional soil. Coco has cation exchange properties that can influence the availability of nutrients including calcium, magnesium and potassium.

A dedicated coco nutrient is therefore preferable to simply applying a standard soil fertiliser. ATA Coco Max is formulated specifically for coco cultivation, providing a nutrient profile designed around plants growing in this type of root environment.

Coco Max A includes calcium as part of its formulation, while Coco Max B supplies complementary phosphorus, potassium and other mineral nutrition required for continued crop development.

Why is ATA Coco Max supplied as A & B?

ATA Coco Max is supplied as two concentrated components because certain mineral nutrients can react with one another when stored together at high concentration.

Separating these nutrients into Coco Max A and Coco Max B keeps the concentrates stable until they are diluted into irrigation water.

The two bottles are complementary components of one nutrient system. Part A is not a grow feed and Part B is not a bloom feed. Both are required together.

Never mix concentrated Coco Max A directly with concentrated Coco Max B. Add Part A to the water first and mix thoroughly. Then add Part B and mix again.

ATA Coco Max A & B nutrient analysis

ATA Coco Max A has an NK 4-0-1 W/W analysis and supplies nitrogen, potassium and calcium as part of the two-part feeding system.

ATA Coco Max B has an NPK 1-4-5 W/W analysis, providing complementary nitrogen together with phosphorus and a higher proportion of potassium.

The complete formulation also supplies essential trace elements required by plants in much smaller quantities but still necessary for normal metabolism and development.

Both components should be used together at equal dosage. Using only one part will not provide the balanced mineral nutrition for which Coco Max is designed.

Calcium nutrition for coco-grown plants

Calcium management is particularly relevant in coco because the substrate's natural cation exchange characteristics can influence calcium availability within the root zone.

ATA Coco Max A contains calcium as part of its mineral formulation, helping provide this essential element within the normal base nutrient.

Calcium contributes to important structural and physiological processes within the plant, including the formation and development of new plant tissues.

This does not mean every crop automatically requires an additional calcium or magnesium supplement. Source-water mineral content, coco preparation, crop demand and the wider feeding programme should be considered before adding further supplements.

One coco base nutrient for growth & flowering

ATA Coco Max is designed to provide the base mineral nutrition required throughout the complete crop cycle.

The same A&B nutrient can remain in use as plants progress from established vegetative growth through flowering and ripening.

Rather than replacing the base nutrient as the crop changes stage, growers can adjust its concentration and introduce appropriate specialist additives according to changing plant requirements.

This provides a straightforward coco feeding system while retaining the flexibility needed for accurate crop management.

How to use Atami ATA Coco Max A&B

Atami's general application rate is 1-4ml/L of Coco Max A plus 1-4ml/L of Coco Max B.

At this dosage, a 10L reservoir requires 10-40ml of A plus 10-40ml of B, a 50L reservoir requires 50-200ml of each, and a 100L reservoir requires 100-400ml of each component.

Add the required amount of Coco Max A to the water first and mix thoroughly. Add the same quantity of Coco Max B afterwards and mix again.

Never combine the concentrated A and B liquids directly.

Adjust final nutrient strength according to crop stage, plant condition, source water, irrigation frequency, environmental conditions and any additional products being used.

Suitable for hand watering & automatic coco irrigation

Coco is particularly well suited to regular irrigation, and commercial crops are often grown using drip systems that apply relatively small amounts of nutrient solution several times during an irrigation period.

ATA Coco Max is a mineral nutrient and can be used with both manual and automatic irrigation systems.

Growers using automatic systems should maintain good reservoir and irrigation-line hygiene and regularly monitor the condition of the nutrient solution.

In intensively irrigated coco systems, irrigation frequency, drainage and root-zone EC should be considered alongside the strength of the incoming nutrient solution.

Managing nutrient strength in coco

Coco performs particularly well when nutrient delivery is consistent and matched to crop demand.

Because ATA Coco Max is a concentrated mineral fertiliser, increasing its application rate increases the EC of the final nutrient solution.

Monitor nutrient strength when changing Coco Max dosage or adding other mineral products, particularly concentrated phosphorus and potassium supplements during flowering.

The correct concentration depends on factors including plant species, crop stage, source water, irrigation strategy, environmental conditions and light intensity.

Using Coco Max with the Atami ATA programme

ATA Coco Max A&B provides the base mineral nutrition around which a wider Atami feeding programme can be built.

A dedicated root stimulator can be used during establishment. ATA-XL can then provide additional growth and flowering support, while Atazyme performs its enzyme-based root-zone and substrate-conditioning role.

As flowering develops, ATA PK 13-14 can be introduced where additional phosphorus and potassium are appropriate for the crop.

These products perform different functions. Coco Max remains the base nutrient while specialist additives are selected according to crop stage and requirements.

ATA Coco Max vs B'cuzz Coco A&B

ATA Coco Max and B'cuzz Coco A&B are both two-part mineral base nutrients developed specifically for coco cultivation, but they belong to different Atami feeding programmes.

ATA Coco Max A&B belongs to the ATA range and provides straightforward complete coco base nutrition through growth and flowering.

B'cuzz Coco A&B forms the base of Atami's wider B'cuzz Coco programme and is designed to integrate with corresponding B'cuzz stimulators and boosters.

Both are dedicated coco nutrients. The choice between them will generally depend on the wider Atami feeding programme being followed.

ATA Coco Max vs a standard soil nutrient

Coco should not be treated exactly like conventional soil or compost because its physical and chemical properties are different.

Soil nutrients are formulated around the buffering capacity and existing fertility normally associated with soil and peat-based substrates.

ATA Coco Max is specifically formulated for coco-based root zones, including calcium within its two-part mineral feeding system.

Growers using coco as their principal substrate should therefore use a nutrient designed specifically for coco rather than assuming a standard soil feed will provide the same nutritional balance.

1L A & 1L B coco nutrient set

This pack contains 1L of Coco Max A and 1L of Coco Max B, providing 2L of concentrated base nutrient in total.

At the recommended 1-4ml/L dosage of each component, the set provides enough A and B to prepare approximately 250-1,000 litres of nutrient solution.

At 1ml/L of each component, the 1L set treats approximately 1,000L. At 2ml/L it treats approximately 500L, and at 4ml/L it treats approximately 250L.

This makes the 1L format particularly suitable for smaller reservoirs, hobby growers, propagation and trial areas, or growers wanting to introduce the ATA coco programme before moving to larger pack sizes.
