Jiffy Grow Block 5 × 5cm

Jiffy Grow Blocks are a reliable and efficient solution for propagating a wide variety of plants, including vegetables, flowers, and ornamental species. Made from 100% RHP Certified coco substrate, each block is supplied as a compact dry plate enclosed in biodegradable netting, making storage and transport highly efficient.
