How does Atami Cocos Substrate work?

This substrate has an open, airy structure, which promotes rapid and robust root systems. It comes pre-washed and steamed to free it from any salts and pathogens.

It contains a light fertiliser and is unique in this. This internal fertiliser contributes to the plants’ accelerated growth in the first week. The product is pre-buffered, so you have much greater control over the pH.

This product works well with seeds and cuttings because cocos are an excellent retainer of nutritious water, which your plant’s root system can readily absorb. The substrate will also remain light, causing the plant’s roots to get much more oxygen. Because of this, your plants will grow healthy and robust root systems and continue to thrive.

This product has RHP certification, which is the Dutch horticultural quality mark and your guarantee and assurance that this product always contains nothing but top-quality ingredients and that they carry a low risk of pests and disease.

How do I use this substrate?

This substrate is a top-quality compost product made mainly of coco (coconut) fibre; it’s 100% natural, and you can use it immediately because it’s pre-washed, steamed and buffered.

If you use this with manual water dispensing, do it daily and in combination with enriched water.

For an automatic process, set this to happen between 1 and 8 times every day, again in combination with enriched water.

The dosage is to work to a proportion of between 1 and 5 litres of nutrient solution per square metre of substrate per day for your adult plants.

Monitor your plants during their growth process to check that they’re healthy and to adjust the dosage accordingly.
