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.
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?
