CANNA Coco Flex 3,8L (1 gal) – compressed coco substrate

CANNA Coco Flex 3,8L (1 gal) – a convenient and innovative coco substrate in compressed blocks

CANNA Coco Flex is a modern, compressed coco substrate designed for professional cultivation where space saving, easy transport, and maximum control over fertilization are essential. The product streamlines cultivation logistics, reduces manual labor, and increases the efficiency of the entire growing system.

Thanks to its compact form and rapid expansion after watering, CANNA Coco Flex is ideal for both indoor growing and advanced commercial installations.

What is CANNA Coco Flex?

CANNA Coco Flex is a 100% natural substrate made from thoroughly washed coconut fiber (coco coir), compressed into blocks and packed in durable, UV-stabilized plastic bags that are recyclable.
The substrate is characterized by:
• uniform particle structure,
• low EC level (<1.0 mS/cm),
• stable pH range of 5.5–7.0,
• complete sterility and consistent quality.
Each CANNA Coco Flex block undergoes strict quality control and is fully traceable, including a quality certificate.

Key advantages of CANNA Coco Flex

• 100% natural coconut fiber – carefully washed and free of contaminants
• Balanced pH: 5.5 – 7.0
• Low EC: below 1.0 mS/cm (1:1.5)
• Uniform particle structure – stable conditions for root development
• No pre-added nutrients – full control over plant nutrition
• Compressed form – saves storage space and reduces transport costs
• Bags with high edges to prevent overflow
• 2 pre-made holes for drip emitters
• Drainage holes at the bottom of the bag for even substrate drying
• UV-resistant, recyclable plastic packaging

Available formats

Expanded volume:

3.8 liters (1 gallon)
• Dimensions before expansion: 13 × 14 × 4 cm
• Dimensions after expansion: 15 × 15 × 15 cm

8 liters (2 gallons)
• Dimensions before expansion: 23 × 18 × 4 cm
• Dimensions after expansion: 25 × 20 × 16 cm

Composition

100% washed coconut fiber (coco coir).
The product is not pre-fertilized and requires the use of suitable coco nutrients such as CANNA Coco A & B.

How to use CANNA Coco Flex?

1. Move CANNA Coco Flex bags directly into the growing area or clean room to simplify logistics and maintain hygiene.

2. After opening the bag, place drip emitters into the prepared holes. Manual watering is also possible.

3. It is recommended to place containers under the bags to collect runoff water.

4. Begin the expansion process using several short irrigation cycles with CANNA Coco A & B nutrient solution.

5. For full expansion, use approximately:
   • 3–4 L of nutrient solution for the 4 L version
   • 6–7 L of nutrient solution for the 8 L version

6. Once the substrate has fully expanded, rooted seedlings or clones can be transplanted.

7. If drip emitters are not used, water gradually from the top in several stages to minimize nutrient loss through the drainage holes.

Applications

• Professional and commercial cultivation
• Indoor growing and clean room environments
• Automated irrigation systems
• Clone and seedling production
• Alternative to traditional coco grow bags and mineral wool

Grower tips

• Use only fertilizers designed for coco cultivation (CANNA Coco A & B).
• Monitor pH and EC of the nutrient solution during the first irrigation cycles.
• Store blocks in a cool, dry place.
• The product is ideal for standardized, repeatable cultivation systems.

CANNA Coco Flex is an innovative, sterile, and extremely user-friendly coco substrate that saves time and space while providing full control over fertilization. An excellent choice for professional growers who value quality, consistency, and production efficiency.
