Grodan Mini Blocks 1.5" 45 blocks per pack

Mini-Blocks sit in a tray (flat) without support for easy starting of seeds and cuttings. These Mini-Blocks are individually wrapped in white plastic to minimize algae growth. Remove wrapping and transplant into any loose media such as Grow-Cubes or coconut fiber or leave wrapping on and set on top of a larger Gro-Block. Packed in easy tear-away strips, labeled with instructions.
