What’s Included in the 50 Cell Seed Starter Kit

• 50 Cell Tray – 1¾" square inches of growing space per cell, 2¼" deep for stronger root development and easy bottom watering.

• Clear 6" Humidity Dome – 5½" interior height with two adjustable vents to control airflow and humidity.

• 1020 Propagation Flat Seed Tray (no holes) – heavy-duty polypropylene plastic built to last a lifetime.

Built to Last Longer Than Standard Seed Trays
