Plan your growing setup

The wide, low-profile block format provides an alternative to upright coco bags. Match substrate volume, plant spacing, and irrigation capacity to your crop and production duration. Place the bag on a suitable support surface and provide a route for irrigation runoff.

Hydration and fertigation

The block ships compressed. Hydrate it according to the manufacturer's current instructions and allow full expansion before planting. Actual hydration time depends on water application and conditions; confirm the block is evenly moistened rather than relying on a fixed expansion time.

Use a nutrient program appropriate for coco-based production and your source-water quality. Monitor root-zone moisture, EC, and pH as plants develop, adjusting irrigation to crop demand and the block's substrate volume.
