Blueberry Farming without Soil – Coco Peat / Coco Coir


Golden Grow Blueberry
Easyplanter Premium 27l Bag


High-quality coconut fibre in ready-to-use individual packaging. Composed of our Golden Grow Hydroponics Premium coconut blend. Thanks to this composition, it is ideal for blueberry cultivation due to its high aeration capacity, avoiding stress caused by root asphyxiation, and at the same time, providing the plant with a reserve of water for critical moments of stress caused by to high temperatures. Facilitates crop management, pH control and electrical conductivity. It comes either in 800 gauge plastic bags with a 5-year warranty and high number of drainage points to facilitate moisture control and washing of salts or without the plastic liner, allowing it to be placed in pots with the same dimensions.

Golden Grow Premium
Blueberry 5kg Blocks


This growing media comes from the mesocarp of the coconut and is intended for hydroponics and/or substrate. Homogeneous product that enables higher yield (expanded kilograms per liter) with a guaranteed quality. This product is available in blocks and briquettes.

Coco peat finest particles are used for propagation: seed, nurseries, tree pots nurseries, seed bed, forestry snd more. It can be used in their pure form or blended with other substrate. Its high water holding capacity and porosity results on top germination rates and a very good root system development. Its light weight makes it ideal to reduce transport cost.

Coco peat has a high water holding capacity (eight times its weight) combined with high porosity (95%) allows an excellent root aeration – oxygenation, producing more functional roots therefore improving plant nutrition and healthier plants.

Excellent re-wetting

Light weight, easy handling

Homogenous and stable structure; long lasting, superior to peat

Totally organic, 100% natural, renewable source

pH slightly acid: 5,5-6,5, suitable for most plants species

Lightweight material ideal for reducing transport costs

Projar Professional Blueberry Mixes for Pots

Projar Sustraberry Blueberry Premium


Substrate based on a mixture of fine blonde peat, black peat, Cocopeat® coconut fibre and perlite. It is a substrate that has great physical stability when transported. In addition, the mixture of black peat and coconut fibre provides a perfect balance for drainage. The proportion of special blonde SOD peat provides nutrients to the substrate, which allow roots to be established properly. The perlite also provides the necessary aeration of the growth medium. This substrate is, therefore, perfect for plants that, like the blueberry plant, require an acidic pH soil level. The optimum range is between 4.5 and 5.5.



pH: 4.5 – 5.5 

Granulometry: 10-40 mm 

Additives: Calcium dolomite 

Size: 120 litre bag / 130 litre bag / maxibale



Durability: 8 years

High drainage capacity

High aeration capacity

No clogging

Sustraberry Blueberry Excellence


Substrate with a coarse structure based on the mixture of selected blonde peat with a proportion of SOD peat, with coconut fibre with a special structure, coarse and with short fibres, and perlite. Thanks to its high proportion of coconut, it is a long lasting substrate, since the coconut degrades less than peat, providing physical stability. In addition, the coconut fibre avoids compaction and, therefore, facilitates proper drainage. The proportion of blonde peat included provides nutrients to the substrate to aid in the proper establishment of roots. The perlite also contributes to the durability and provides the growth medium with the necessary aeration. This substrate is, therefore, perfect for plants such as the blueberry plant, which requires an acidic pH soil level. The optimum range is between 4.5 and 5.5.



pH: 5.5-6.5

Granulometry: 10-40 mm 

Additives: Dolomite lime: 1-3 kg/m3
