GRODAN® Stonewool Delta Starter Mini-Blocks

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.
