50 Cell Seed Starting Tray Inserts

Deep Cells for Stronger Seedlings

Durable plug tray inserts designed to give seedlings more room to grow before transplanting.

The 50-Cell Seed Starting Tray Inserts are ideal for starting vegetables, flowers, and herbs that benefit from deeper cells and additional root space. Each cell extends fully to the bottom of a standard 1020 tray, making these inserts especially well suited for bottom watering and consistent moisture delivery.

Made from extra-strong, BPA-free, food-safe plastic, these trays are built for repeated use and reliable performance season after season.
