Atami ATA Coco Max A&B 5L is a professional two-part mineral base nutrient developed specifically for plants grown in coco and coco-based substrates. Designed for use throughout the crop cycle, it provides balanced mineral nutrition to support strong growth, flowering and fruit development in coco.

Coco combines excellent water retention with a naturally open and well-aerated root environment, but its nutritional behaviour differs from conventional soil. ATA Coco Max is formulated specifically for coco cultivation rather than being a general-purpose fertiliser adapted for use in coco.

The nutrient is supplied as two complementary concentrates, Coco Max A and Coco Max B. The two parts work together to provide the primary and secondary nutrients required by plants while allowing the concentrated mineral components to remain stable during storage.

ATA Coco Max can remain the base nutrient as plants move from rooting and vegetative development through early bloom, full flowering and ripening. Atami's current coco feeding programme varies the concentration according to crop stage, with lower rates during establishment and stronger feeding during active growth and flowering.

This 5L set contains 5L of Coco Max A and 5L of Coco Max B, giving 10L of concentrated two-part coco nutrition in total.

Professional base nutrition for coco cultivation

Coco coir is widely used by professional and hobby growers because it combines excellent moisture retention with an open structure that allows oxygen to remain available around the root system.

Unlike conventional compost or soil, however, coco provides very little complete nutrition of its own. Successful coco cultivation therefore relies heavily on the nutrient solution supplied by the grower.

ATA Coco Max is designed specifically to provide this nutritional foundation. Rather than trying to adapt a soil fertiliser to a different growing medium, growers can use a dedicated coco base nutrient formulated around the requirements of coco-grown plants.

This makes nutrient management more predictable and allows the grower to build a complete crop-stage programme around a consistent base feed.

Why does ATA Coco Max come in two parts?

Some mineral nutrients react with one another when stored together at high concentration. These reactions can create compounds that are no longer readily available to plants.

ATA Coco Max therefore separates its concentrated mineral nutrition into Part A and Part B. The components remain separate until they are diluted into water.

Coco Max A and Coco Max B are complementary parts of the same nutrient. They are not separate grow and bloom fertilisers, and both should be used together.

Never mix the concentrated A and B liquids directly together. Add Part A to the reservoir water and mix thoroughly before adding Part B.

One coco base nutrient throughout the crop cycle

One of the main advantages of ATA Coco Max is that the same two-part base nutrient can remain in use throughout the crop cycle.

Instead of replacing the base fertiliser as the plant changes developmental stage, growers adjust the concentration of Coco Max A&B and introduce specialist additives where required.

Atami's current Coco Max grow programme uses lower concentrations during the rooting phase, followed by stronger feeding through growth, early bloom, bloom and ripening.

This allows the nutrient programme to follow the changing demand of the crop while retaining the same nutritional foundation.

How to use Atami ATA Coco Max A&B

Coco Max A and B should always be used in equal concentrations. Atami's current coco programme typically uses approximately 1-2ml/L of each component during rooting and 3-4ml/L of each during established growth and flowering.

For a 100L reservoir, 1-4ml/L corresponds to 100-400ml of Coco Max A plus 100-400ml of Coco Max B. For 500L, this equals 500ml-2L of each component. For 1,000L, use 1-4L of each component.

Add the required amount of Coco Max A to the water first and mix thoroughly. Then add the same concentration of Coco Max B and mix again.

Never combine the concentrated A and B components before dilution.

Atami's grow guides are general guidelines. Final concentration should be adapted to crop species, plant size, development stage, source water, irrigation frequency, environmental conditions and the other products included in the nutrient programme.

Ideal for regularly irrigated coco crops

Coco is particularly well suited to frequent irrigation because its physical structure can retain moisture while maintaining oxygen around the roots.

ATA Coco Max is suitable for both hand watering and automatic irrigation, making it useful across everything from individual coco pots to larger drip-irrigated growing areas.

In intensive coco production, growers should consider irrigation frequency and drainage alongside the strength of the incoming nutrient solution.

Monitoring both feed and root-zone conditions can help identify nutrient accumulation and allows irrigation or nutrient strength to be adjusted before crop performance is affected.

Managing nutrient strength in coco

Because ATA Coco Max is a concentrated mineral nutrient, its application rate directly affects the EC of the final nutrient solution.

Young or recently rooted plants generally require a lower nutrient concentration than established plants under active growth or flowering conditions.

As crop demand increases, Coco Max concentration can be increased accordingly. If additional mineral products such as PK flowering additives or CalMag are introduced, their contribution to the total nutrient strength should also be considered.

Professional growers should base final feed strength on crop response, source-water EC, growing environment and measured root-zone conditions rather than relying solely on a fixed feeding schedule.

Using Coco Max with the Atami ATA programme

ATA Coco Max A&B provides the base mineral nutrition within Atami's ATA coco programme.

During initial establishment, a dedicated root stimulator such as Rootfast or Rootbastic can be incorporated according to the chosen programme.

Once active growth is established, Atazyme can be used for enzyme-based root-zone support, while specialist flowering additives can be introduced as the crop moves into bloom and ripening.

Atami's current Coco Max programmes include options incorporating products such as ATA PK 13-14, Bloombastic, Rokzbastic, CalMag and B'cuzz Silic Boost depending on the grower's chosen feeding strategy.

Coco Max remains the base nutrient while these additional products perform their more specialised roles.

Do coco plants always need additional CalMag?

Calcium and magnesium management can be particularly important in coco, but an additional CalMag product should not automatically be added at maximum strength to every nutrient solution.

The requirement depends on factors including source-water mineral content, the condition and preparation of the coco, crop species, plant demand and the complete nutrient programme.

Atami's current Coco Max feeding programmes include ATA CalMag as an optional part of complete feeding schedules, with the concentration adjusted according to crop and growing conditions.

Growers using soft or reverse-osmosis water may have different supplementation requirements from growers using harder source water containing appreciable calcium and magnesium.

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 designed specifically for coco cultivation, but they belong to different Atami feeding programmes.

ATA Coco Max A&B belongs to Atami's ATA range and provides the base nutrition for the ATA coco programme.

B'cuzz Coco A&B forms the base of the B'cuzz Coco programme and is designed to integrate with products such as Coco Booster Uni and Coco Bloom Stimulator.

Both are dedicated coco nutrients. The appropriate choice will normally depend on which wider Atami nutrient programme the grower intends to follow.

ATA Coco Max vs soil nutrients

Coco should not be treated exactly like conventional soil or potting compost because its nutrient-holding characteristics and inherent fertility are different.

Soil nutrients are formulated around the properties of soil or peat-based growing media, while ATA Coco Max is designed specifically for coco-based root zones.

Growers using coco as their principal growing medium should therefore use a dedicated coco nutrient rather than assuming a standard soil feed will provide the same nutritional balance.

5L A & 5L B for larger coco systems

This set contains 5L of Coco Max A and 5L of Coco Max B, providing 10L of concentrated two-part nutrient in total.

Across a 1-4ml/L application range, each 5L component is sufficient for approximately 1,250-5,000 litres of nutrient solution.

At 1ml/L of each component, the set treats approximately 5,000L. At 2ml/L it treats approximately 2,500L, at 3ml/L approximately 1,667L, and at 4ml/L approximately 1,250L.

The 5L format is particularly suitable for larger reservoirs, regular coco growers and commercial horticultural production where a consistent base nutrient is required throughout the crop cycle.
