High Porosity Cocos


High Porosity Cocos (HPC) combines the properties of ATAMI’s Cocos Substrate with perlite for increased substrate airiness. The coco of Atami is known to be very clean and low in detrimental salts, while also containing a balanced fertilizations. To achieve this, the coco is ripened, washed, buffered and lightly fertilized.

Perlite is volcanic rock that has been formed during volcanic eruptions. It is treated with a high temperature to make it expand. You can compare it to popcorn. When we heat a corn grain, it pops into an airy treat. The same can happen to perlite, which pops into a porous structure of about twenty times its original size. By mixing this perlite through your substrate, the airiness of your substrate is greatly increased.

Due to the addition of perlite to the coco, the product reaches an air-percentage of about 30%. The availability of air is essential for the development of roots. Plants require oxygen to ‘burn’ sugars and use them up for their energy. Through the use of this energy, the root system expands and develops further.

• Airy structure
• Great water management
• Optimal root development

Cocos Substrate


Cocos Substrate is a high quality compost comprised of coco fibres extracted from the mesocarp of the coconut. It is a 100% natural product and designed so that it can be used immediately.

Cocos Substrate is produced under controlled conditions, which is an assurance of quality and offers the ability to use it over and over again after each growing cycle. It can absorb plenty of water in a short period of time and can also deliver water rapidly and abundantly.

The roots also have plenty of available oxygen, which keeps them active. Despite the absence of residual water, there is always enough humidity for the plant.

• Airy structure
• High quality coco
• Optimal root development

Hydro Rokz Cocos 60-40


Cultivation on a coco substrate and hydroponic growing are popular cultivation methods. Every grower has his own preference and every substrate has its own characteristics! Why wouldn’t you combine best of both worlds?!

With this in mind Atami has developed Hydro Rokz Cocos 60-40!

The substrate is a well-balanced blend of clay pebbles and top quality coco peat.

Hydro Rokz Cocos 60-40 offers many benefits of growing hydroponically. The clay pebbles provide excellent drainage as they retain nearly no water!
This decreases the risk of over-watering. When the water is drained, fresh air enters the root zone and gives this substrate a high air ratio, for optimal root development!

Adding coco increases the water retention of the substrate. Coco offers a buffer between watering times, as makes sure moisture levels near the roots stay stable. And, it holds on to some nutrients as well!

Hydro Rokz Cocos 8-16


Hydro Rokz are made of pure and salt-free baked clay. They contain a very low concentration of elements and this makes them ideal as a substrate for hydroculture. The quality of the clay pebbles is largely determined by the pH value.

Clay pebbles are used for various growing methods. Sometimes they are placed at the bottom of the flowerpot when growing on a soil substrate like soil. The Hydro Rokz are also used as an additional drainage.

Hydro Rokz can be mixed with the substrate to make the growing medium airier, so the roots can also branch off better. Another method that is widely used, is growing the plants directly on Hydro Rokz. This is often done in combination with an oxygen pump. This way the roots at the bottom of the pot are constantly immersed in water with liquid fertilisers mixed in, and the oxygen pump provides enough oxygen for the roots.

Growing hydroponically with Hydro Rokz is very successful, because the clay pebbles and the flowing water nutrient solution are a golden duo when it comes to a lavish supply of oxygen. The plants both get oxygen from the top and from below. The flowing water contains many times more oxygen than ordinary still water.

• Easy to use
• Airy structure
• Strong, healthy roots

Wilma Large 4 Complete 11L / 18L


Wilma Large 4 Complete is a nursing tray with four 11 litres pots. This way the plants have sufficient space to develop optimally.
The Wilma growing system is like a pot with a personal assistant which feeds the plants little and often.

This way the plants get the nutrients and water for optimum growth. The plants are able to take up more water and nutrients and they are never over or underfed or watered, which makes the Wilma system producing bigger yields compared with regular pots.

The growing system is light in weight and easy to move. It’s very stable in the nursing area, allowing the plants to stay neatly upright, even when they have grown large.

The pots are filled with your chosen growing medium and a pump delivers the nutrient solution through the drippers into the pots. Perfect if you want the familiarity of pots and the increased yields produced by plants fed little and often.

Wilma Large 4 Complete has been especially designed for the enthusiastic grower who wants to grow at home!
