The Mr. Pen Seed Starter Tray Kit is designed to make seed starting approachable and efficient. With a total of 350 cells spread across five sturdy trays, this set helps you plan and monitor multiple plant varieties side by side. Built from durable, reusable plastic, the trays resist warping and stay ready for season after season. The included humidity domes are topped with adjustable vents, offering a practical way to balance warmth and moisture as seeds begin to sprout. The transparent lids create a gentle greenhouse effect, helping young roots and shoots establish themselves in a stable, inviting microclimate.
