Mr. Pen Seed Starter Tray Kit - 5 Pack, 350 Cells, Humidity Dome Germination Trays

Effortless seed starting with a robust 5-pack tray kit

The Mr. Pen Seed Starter Tray Kit helps you organize and streamline seed starting. The set includes five trays that total 350 cells, providing ample space to test multiple varieties at once. The sturdy, reusable plastic stands up to repeated use season after season, resisting warping and deformation that can disrupt germination.

Each tray works with humidity domes designed to keep air evenly moist and for warmth. The domes feature adjustable vents that let you dial in temperature and moisture as your seedlings grow. When you snap on the transparent lids, you create a mini greenhouse effect on your countertop or worktable, helping young plants stay cozy and thriving even in cooler rooms.
