Atami Cocos Substrate 100L – Coconut Substrate for Cultivation

Frequently asked questions

• What is Atami Cocos Substrate 100L?

  It's a professional 100% natural coco fibre substrate made by Atami, a Dutch brand that's a world reference in growing substrates. Its coco fibre is washed and steamed, so it arrives free of salts and pathogens, and it carries RHP certification, a guarantee of quality and sustainability.

• Do I need to fertilise from the first watering with this substrate?

  It's not essential, because the coco provides enough food for the first week of growing, which greatly simplifies the initial fertilising. Its pH 6.0 and EC of 0.80-1.00 mS/cm values are also ideal for starting the grow in a balanced way. From there you can continue with your usual nutrient programme.

• What's the composition of Atami Cocos Substrate?

  Its composition includes washed and steamed coco fibre, mineral lime and calcium nitrate. It contains over 85% organic matter by dry weight — a clean, light and highly efficient formula for developing healthy roots.

• What advantages does its structure offer for the roots?

  The structure of Atami's fibre allows for optimal storage of the nutrient solution and fast absorption by the roots. The substrate stays light and well oxygenated at all times, resulting in more vigorous plants, dense roots and a noticeable improvement in growth and final yield.

• What fertilisers can I combine this coco substrate with?

  It's the ideal choice to combine with the Atami B'Cuzz fertiliser line from the same brand. It also works perfectly with any other nutrient programme specifically designed for coco growing.

  The 100L bag is a practical size designed for growers who need a large volume of substrate. If you order it from our shop, shipping takes 24/72h and you get easy returns within 15 days.
