Exploring Seed Trays: With or Without Drainage Holes?

When contemplating seed trays, the crucial question arises: should they have drainage holes or not? The answer is multifaceted and varies based on the gardening needs and plant types.

Differences in Seed Tray Design

All seed trays are designed to hold soil for growing seedlings; however, their configurations differ significantly. The choice between trays with drainage holes and those without can critically affect plant health.

The Impact of Drainage Holes

Trays equipped with drainage holes facilitate excess moisture to escape, preventing waterlogging which can cause root rot. They suit plants that thrive in standard watering conditions. Conversely, trays without holes retain moisture for a longer time, benefiting plants that prefer high humidity. Understanding your plants' water requirements is essential for proper selection.

Why Cell Size Matters in Seed Trays

When selecting seed trays, consider cell size and count. Smaller cells may save space but can restrict root growth, leading to seedlings becoming root-bound. Conversely, larger cells provide necessary room for healthy root development.
