An essential component for serious propagators and growers, this square gravel tray from Stewart Plastics supports the critical early stages of seed development and plant establishment. The sturdy, durable construction withstands repeated use throughout the growing season. Fill with gravel to create an effective moisture reservoir, then position plant pots on top for controlled watering directly into the base layer. This method minimises water splashing whilst maintaining consistent moisture levels around developing root systems. The 54cm dimensions provide ample space for multiple specimens, making it indispensable for anyone committed to raising healthy, vigorous plants from seed through to growing-on stages.
