Jiffy Grow Block 8 × 8cm

Jiffy Grow Blocks are an efficient and reliable solution for propagating vegetables, flowers, and ornamental plants. Made from 100% RHP Certified coco substrate, each block is supplied as a compact dry plate enclosed in biodegradable netting, allowing for easy storage and cost-effective transportation.

Once water is added, the plate expands into a ready-to-use grow block, providing a clean and stable growing environment. The surrounding netting keeps the substrate intact, supports root development, and helps maintain a tidy greenhouse or propagation area.
