Size:1800 Blocks Starter Mini-Blocks can sit in a tray (flat) without support for easy starting of seeds and cuttings. They are individually wrapped to minimize algae growth. For best results put them on the flat side of the Gro-Smart Tray to ensure good airflow around the cubes. Remove wrapping and transplant into any loose media such as Grow-cubes or Grow-Chunks, or leave wrapping on and set on top of a larger Gro-Block. These cubes are popular for production of aquatic plants. The advantage Mini-Blocks have over A-OK Starter Plugs and Macro Plugs is that Mini-Blocks can sit in a tray without support.
