Grow1 USA Premium 50 Cell Seedling Plug Tray (10" x 20")
The Grow1 USA Premium 50 Cell Seedling Plug Tray is a heavy-duty solution for growers who need more than just a single-season tray. Proudly made in the USA from a thicker, higher-grade plastic, these trays are significantly more sturdy than standard propagation inserts. Designed to flex without cracking, they withstand the rigors of repeated handling and transplant cycles while maintaining their structural integrity.
Featuring 50 deep square cells, this tray is specifically engineered for crops that benefit from a stronger head start. With a 2.5-inch depth, it provides ample vertical space for aggressive root development—making it the ideal choice for starting tomatoes, peppers, and larger ornamentals. For growers requiring higher density, the
Grow1 USA Premium X-Deep 72-Cell Seedling Plug Tray offers the same heavy-duty construction with more planting sites.
This premium insert is sized to fit perfectly inside
USA Made propagation trays. While it provides a snug fit for most square media, it also accommodates round plugs like Cultiwool Macro Plugs with a secure, tight fit that leaves a small portion of the plug exposed for easy grasping during transplanting. Each cell includes built-in drainage to ensure high oxygen levels and prevent waterlogged roots.
