A premium 100% washed and buffered coco coir growing medium with no added fertiliser and an exceptionally low EC below 0.3 mS/cm, giving growers complete control over crop nutrition from the very beginning.
Atami Washed & Buffered Cocos is a high-quality coco fibre substrate designed for growers who want to start with a clean, low-EC growing medium and manage their own nutrient programme from the outset. Unlike Atami's standard Cocos Substrate, Washed & Buffered Cocos contains no added fertiliser.
The coco fibres are thoroughly washed to help remove unwanted salts and then buffered to condition the natural exchange sites within the coco. This processing creates a stable, grow-ready substrate and helps prevent the coco from interfering unnecessarily with the calcium and magnesium supplied through the nutrient solution.
With an EC below 0.3 mS/cm, Washed & Buffered Cocos provides an excellent blank canvas for growers who want precise control over nutrient strength and composition. Because there is no starter fertiliser within the substrate, a suitable coco nutrient programme should be introduced from the beginning.
Coco fibre naturally combines excellent moisture retention with a light and airy structure. This creates a highly effective balance between water availability and oxygen around the root zone, making Atami Washed & Buffered Cocos suitable for propagation, young plants and established crops.
Why choose Atami Washed & Buffered Cocos?
- 100% premium coco fibre – a high-quality coco coir substrate without added peat or pre-fertilisation.
- Washed coco – processed to help remove naturally occurring salts and residues that can increase substrate EC.
- Properly buffered – conditioned to help manage the natural interaction between coco fibre, calcium, magnesium, potassium and sodium.
- Exceptionally low EC – Atami specifies an EC below 0.3 mS/cm.
- No added fertiliser – gives the grower control over nutrition from the beginning of cultivation.
- Ideal for seedlings & cuttings – the low initial nutrient content makes it particularly suitable for young plants and propagation.
- Excellent moisture retention – coco holds a useful reserve of water around the root zone.
- Light & airy structure – maintains oxygen around developing roots while retaining moisture.
- Suitable throughout the crop cycle – can be used from propagation and early growth through to mature crops.
- Excellent for controlled feeding – particularly useful where growers want to manage nutrient concentration and EC themselves.
What is Atami Washed & Buffered Cocos suitable for?
Atami Washed & Buffered Cocos is particularly well suited to growers who want to control crop nutrition from the very beginning rather than relying on fertiliser incorporated into the growing medium.
Its very low initial EC and lack of added fertiliser make it an excellent choice for seedlings, rooted cuttings and young plants, where precise control over nutrient strength can be particularly useful.
It can also be used as the primary growing medium throughout the complete crop cycle. As plants establish and their nutritional requirements increase, the nutrient programme can be adjusted according to crop type, development stage and environmental conditions.
Coco is widely suited to hand watering and automated irrigation systems. Its combination of moisture retention, drainage and root-zone aeration makes it particularly useful for intensive container cultivation and drip-irrigated crops.
How to use Atami Washed & Buffered Cocos
Atami Washed & Buffered Cocos is supplied ready for use. Fill the required pots or containers with the substrate and introduce an appropriate coco-specific nutrient programme from the beginning of cultivation.
Because the substrate contains no added fertiliser, plants depend on the nutrient solution for their nutritional requirements. Feed strength should therefore be appropriate for the crop and its stage of development rather than applying one fixed EC throughout the entire crop cycle.
Atami recommends monitoring both pH and EC when cultivating in coco. Their coco-growing guidance recommends maintaining the nutrient solution at approximately pH 5.5–6.2, while EC should be adjusted according to crop requirements and development stage.
Calcium and magnesium availability is particularly important in coco cultivation. Atami recommends a coco-specific feeding programme and identifies CalMag supplementation as useful where additional calcium and magnesium are required.
When watering, allow the coco to dry slightly between irrigations but do not allow the substrate to dry out completely. Irrigation frequency should be adjusted according to plant size, root development, temperature, humidity, container size and the rate at which the substrate is using water.
What does washed and buffered coco mean?
Raw coco fibre naturally contains soluble salts and has exchange sites that can interact strongly with nutrients. High-quality horticultural coco therefore requires more processing than simply drying and bagging coconut fibre.
Washing helps remove salts and residues from the coco, reducing its starting electrical conductivity and creating a cleaner growing medium.
Buffering conditions the coco's exchange sites before cultivation. During the buffering process, calcium and magnesium are used to displace naturally occurring sodium and potassium from these sites. This helps prevent untreated coco from tying up calcium and magnesium when nutrient solution is subsequently applied.
The result is a cleaner and more predictable coco substrate that is ready to receive a controlled nutrient programme.

Atami Washed & Buffered Cocos 50L FAQs
What is Atami Washed & Buffered Cocos?
Atami Washed & Buffered Cocos is a 100% coco fibre growing medium that has been washed and buffered before use. It contains no added fertiliser and has a very low EC, allowing growers to control nutrition from the beginning.
Does Atami Washed & Buffered Cocos contain nutrients?
No. Atami specifically produces this substrate without added fertiliser. A suitable coco-specific nutrient programme should therefore be introduced from the beginning of cultivation.
What is the EC of Atami Washed & Buffered Cocos?
Atami specifies an EC below 0.3 mS/cm. This exceptionally low starting EC gives growers considerable control over the nutrient concentration supplied to the crop.
What does washed coco mean?
Washing coco helps remove naturally occurring salts and residues from the fibre. This helps reduce the starting EC and produces a cleaner growing medium for horticultural use.
What does buffered coco mean?
Buffering conditions the natural exchange sites within coco fibre. Calcium and magnesium are used during processing to displace sodium and potassium from these sites, helping to create a more stable substrate before the crop's nutrient solution is introduced.
Why is buffered coco better than untreated coco?
Proper buffering helps prevent coco from binding excessive calcium and magnesium when plants are subsequently fed. This gives growers a more predictable root-zone environment and greater control over crop nutrition.
Is Atami Washed & Buffered Cocos ready to use?
Yes. The coco has already been washed and buffered by Atami and is supplied ready for cultivation. Because it contains no added fertiliser, begin an appropriate nutrient programme when planting.
Is Atami Washed & Buffered Cocos suitable for seedlings?
Yes. Atami specifically identifies Washed & Buffered Cocos as ideal for seedlings. Its lack of added fertiliser allows the grower to control nutrient strength during early development.
Can I use Atami Washed & Buffered Cocos for cuttings?
Yes. The low-EC, non-fertilised substrate is particularly suitable for cuttings and young plants where careful control over nutrition is desirable.
Can Atami Washed & Buffered Cocos be used for the full crop cycle?
Yes. Although particularly useful for propagation and young plants, the substrate can be used throughout the complete crop cycle when paired with an appropriate coco nutrient programme.
Do I need to feed from the start when using Atami Washed & Buffered Cocos?
Yes. There is no added fertiliser in the substrate, so Atami recommends introducing the chosen nutrition from the beginning of cultivation.
Do I need CalMag with Atami Washed & Buffered Cocos?
The coco is already buffered, so it does not need to be re-buffered before use. However, calcium and magnesium remain important nutrients when growing in coco. Atami recommends monitoring crop requirements and using a suitable CalMag supplement where additional calcium and magnesium are needed.
What pH should I use with Atami coco?
Atami's coco cultivation guidance recommends keeping the nutrient solution within approximately pH 5.5–6.2. Regular monitoring is advisable because coco has less pH buffering capacity than peat-based growing media.
How often should Atami Washed & Buffered Cocos be watered?
There is no single irrigation schedule suitable for every crop. Atami recommends allowing the coco to dry slightly before watering again while never allowing it to dry out completely. Irrigation frequency should be adjusted according to crop size, container size and environmental conditions.
Should coco coir be allowed to dry out completely?
No. Atami advises against allowing coco to dry out completely. Its moisture level should be managed so that the substrate dries slightly between irrigations while maintaining moisture around the root zone.
Can Atami Washed & Buffered Cocos be used with drip irrigation?
Yes. Coco coir is particularly well suited to drip irrigation and other controlled irrigation systems because of its combination of moisture retention, drainage and root-zone aeration.
What is the difference between Atami Washed & Buffered Cocos and Atami Cocos Substrate?
The main difference is pre-fertilisation. Washed & Buffered Cocos contains no added fertiliser and has an EC below 0.3 mS/cm. Atami Cocos Substrate is lightly fertilised and has a higher specified EC, providing some initial nutrition before the grower takes over the feeding programme.
Does Atami Washed & Buffered Cocos contain peat?
No. Atami describes the substrate as being composed of 100% coco fibre.
Is Atami Washed & Buffered Cocos good for professional growers?
Yes. Its low starting EC and absence of added fertiliser make it particularly useful where precise control over irrigation and crop nutrition is required, including intensive and professional growing programmes.
How large is a bag of Atami Washed & Buffered Cocos?
Each bag contains 50 litres of washed and buffered coco coir growing medium.
How many bags of Atami Washed & Buffered Cocos are on a pallet?
A full pallet contains 75 x 50L bags. Individual 50L bags can still be ordered separately.

Atami High Porosity Cocos 50L is a premium 70/30 coco and perlite growing medium combining aged, washed and buffered coco fibre with 30% perlite for increased drainage, aeration and oxygen availability throughout the root zone.
Designed for growers who want the benefits of high-quality coco with an even more open and free-draining structure, Atami High Porosity Cocos combines 70% coco with 30% perlite. The additional perlite increases air-filled porosity and drainage, creating an excellent environment for intensive root development.
The coco used by Atami is carefully aged, washed and buffered before use. Washing helps remove excess salts and residues, while buffering stabilises the coco's nutrient exchange characteristics before plants are introduced.
Unlike Atami Washed & Buffered Cocos, which contains no added fertiliser, High Porosity Cocos is pre-fertilised. This makes it a ready-to-use coco growing medium while still allowing growers to manage crop nutrition through a suitable coco feeding programme as the crop develops.
The 70/30 coco-perlite combination is particularly suited to growers using frequent irrigation, drip systems and intensive container cultivation where rapid drainage and high root-zone oxygen availability are desirable.
Why choose Atami High Porosity Cocos?
- 70/30 coco & perlite blend – combines 70% high-quality coco with 30% perlite for increased porosity.
- Excellent root-zone aeration – the open structure helps maintain a continuous supply of air around developing roots.
- Increased drainage – added perlite allows irrigation water to move efficiently through the growing medium.
- Supports intensive root development – high oxygen availability helps create favourable conditions for root expansion and root-hair development.
- Aged coco fibre – Atami carefully ages its coco as part of the preparation process.
- Washed coco – washing removes unwanted salts and residues that could otherwise influence substrate EC.
- Buffered coco – the coco is buffered before use to provide a more stable and balanced growing medium.
- Pre-fertilised – supplied with an initial nutrient charge rather than being completely unfertilised.
- Suitable for frequent irrigation – the high drainage capacity makes it particularly useful in intensively managed irrigation programmes.
- Ready-to-use 50L format – suitable for individual pots, larger containers and professional growing applications.
What is Atami High Porosity Cocos suitable for?
High Porosity Cocos is designed for crops grown using coco-based cultivation where growers want greater drainage and root-zone aeration than conventional pure coco provides.
The 30% perlite content makes the substrate particularly useful for growers using frequent irrigation or automated drip systems. The increased drainage allows irrigation events to replenish the root zone while maintaining a high proportion of air-filled pore space.
It can be used in individual pots and containers as well as larger professional growing systems. The physical characteristics make it particularly relevant to intensive cultivation where irrigation, nutrient strength and runoff are actively managed.
Growers moving from conventional coco should account for the increased drainage. Atami specifically recommends increasing watering to match the greater drainage capacity of High Porosity Cocos.
How to use Atami High Porosity Cocos
High Porosity Cocos is supplied ready for use. Fill the required pots or containers with the substrate while avoiding excessive compression, as maintaining the open structure is important to its aeration and drainage characteristics.
Transplant into the substrate and irrigate according to crop size, container volume and environmental conditions. Because the medium contains 30% perlite, it drains more rapidly than conventional coco and irrigation frequency may need to be increased accordingly.
Atami specifically advises growers to increase watering to match the increased drainage of High Porosity Cocos. This does not simply mean applying excessive water at each irrigation. The irrigation strategy should be adjusted to the crop and growing environment, with frequency and volume managed to maintain the desired moisture and air balance.
High Porosity Cocos is pre-fertilised, so its existing nutrient content should be considered when establishing the initial feeding programme. As plants develop, use an appropriate coco nutrient and monitor nutrient solution strength according to crop requirements.
As with other coco-based growing systems, monitoring irrigation, EC and crop response provides greater control than relying on a fixed watering or feeding schedule.
Why does high porosity matter?
Healthy roots require both water and oxygen. When a growing medium remains excessively saturated or compacted, the amount of air available around the roots can decrease.
Atami adds 30% perlite to High Porosity Cocos specifically to increase air availability and drainage. Perlite creates additional pore space within the coco, helping the root zone retain an open physical structure following irrigation.
Atami explains that oxygen is required by roots to process sugars into usable energy. This energy supports root expansion and the plant's ability to actively supply nutrients throughout the crop.
The combination of coco's useful moisture-holding characteristics with the increased air space provided by perlite creates a substrate suited to growers looking for a high air-to-water ratio and rapid drainage.
Why are the coco fibres washed and buffered?
Quality coco requires preparation before it becomes a reliable growing substrate. Atami ages, washes and buffers its coco to produce a cleaner and more stable root-zone environment.
Washing helps remove salts and residues that can increase the electrical conductivity of untreated coco. Buffering is a separate process that conditions the natural exchange sites within coco and helps balance elements such as calcium and magnesium before cultivation begins.
This preparation means growers receive a professionally processed coco substrate rather than untreated raw coir. High Porosity Cocos then adds 30% perlite to this prepared coco to further increase aeration and drainage.
High Porosity Cocos vs standard Atami coco
Atami High Porosity Cocos is designed for growers who specifically want additional aeration and drainage. The addition of 30% perlite gives it a more open structure than Atami's standard Cocos Substrate.
It also differs from Atami Washed & Buffered Cocos. Washed & Buffered Cocos is a 100% coco product with no added fertiliser and an exceptionally low EC, giving experienced growers a blank canvas for their own nutrition programme.
High Porosity Cocos is instead a pre-fertilised 70/30 coco-perlite medium, designed to combine processed coco with increased air space and faster drainage.

Is Atami High Porosity Cocos pre-fertilised?
Yes. High Porosity Cocos is pre-fertilised. This is an important difference from Atami Washed & Buffered Cocos, which contains no added fertiliser.
What is the EC of Atami High Porosity Cocos?
Atami specifies an EC of less than 1.5 for High Porosity Cocos.
Why is perlite added to coco?
Perlite creates additional air-filled pore space within the substrate. In High Porosity Cocos, the 30% perlite content increases drainage and helps maintain oxygen availability around the root system.
Does High Porosity Cocos need more frequent watering?
Potentially, yes. Atami specifically advises increasing watering to match the increased drainage of High Porosity Cocos. The actual irrigation frequency should be adjusted according to crop size, container volume and environmental conditions.
Is Atami High Porosity Cocos suitable for drip irrigation?
Yes. Its high drainage and aeration make it particularly well suited to controlled and frequent irrigation strategies, including drip-irrigated coco cultivation.
Do I need to add extra perlite?
No additional perlite is normally required. High Porosity Cocos already contains 30% perlite and has been specifically formulated to provide a high level of aeration and drainage.
What is the difference between High Porosity Cocos and Atami Cocos Substrate?
Both use processed, pre-fertilised Atami coco, but High Porosity Cocos contains 30% perlite. This gives it increased aeration and drainage compared with the standard Cocos Substrate.
What is the difference between High Porosity Cocos and Washed & Buffered Cocos?
High Porosity Cocos is a pre-fertilised 70/30 coco-perlite growing medium. Washed & Buffered Cocos is 100% coco with no added fertiliser and an EC below 0.3, making it more suitable for growers wanting complete control of nutrition from the start.
Why is oxygen important in a coco root zone?
Roots require oxygen for respiration and energy production. Maintaining an airy root zone supports root expansion and the development of root hairs involved in water and nutrient uptake.
Can High Porosity Cocos be used for professional growing?
Yes. The combination of controlled drainage, high porosity and processed coco makes it particularly useful for professional and intensive coco cultivation where irrigation and crop nutrition are actively managed.
Is Atami High Porosity Cocos ready to use?
Yes. The coco has already been aged, washed, buffered and pre-fertilised, and the perlite is incorporated into the mix. It can therefore be used directly from the bag.
How many bags of Atami High Porosity Cocos are on a pallet?
A full pallet contains 70 x 50L bags of Atami High Porosity Cocos.
