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.
- Made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs
- Has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth
- Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums
