Description

Starter Mini-Blocks can sit in a tray (flat) without support for easy starting of seeds and cuttings. 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. Mini-Blocks can sit in a tray without support.
