CANNA Coco Flex Case - 4L(~1 Gal) (40/Case)

CANNA COCOflex 4L coco grow bags combine compressed, 100% coco coir with an open-top, recyclable plastic bag for efficient garden setup. This case of 40 offers a uniform growing medium for large-scale facilities, with consistent particle size and two irrigation-dripper holes in each block.

Made from high-quality coconut fiber pith sourced from coconut processing in India, COCOflex is carefully washed and quality-controlled for a homogeneous structure. The compact, expandable format reduces labor and storage needs while helping standardize your grow.

Hydration and nutrient application

Suitable for all plant material. COCOflex is not pre-fertilized: expand it with a suitable coco-based fertilizer, such as CANNA Coco A&B or CANNA Coco HC A&B. Apply nutrient solution slowly until the block is fully expanded and runoff appears.

• 4L COCOflex: approximately 3–4 L of nutrient solution for full expansion.
• 8L COCOflex: approximately 6–7 L of nutrient solution for full expansion (reference for the larger size; this listing is the 4L case).
