Grow1 Premium 50-Cell Seedling Plug Tray - 10" x 20"

A 50-cell tray provides larger individual cells, which means more soil volume per plant. This is crucial for crops like tomatoes and peppers that grow rapidly and need more space for roots to develop before they become root-bound compared to seedlings in a 72-cell plug tray.

This specific model is designed to fit INSIDE a standard 1020 propagation tray. This allows you to bottom-water your seedlings by filling the base tray, encouraging roots to grow downward toward the moisture.

Because these cells are square and the plugs are round, they provide a very snug, secure fit. About 1/8" of the plug will remain exposed above the surface of the tray, making it easy to grab and move the plugs when it's time to transplant.

Yes, these trays are made from high-quality horticultural plastic designed for seed starting and plant propagation, ensuring they are safe for vegetables, herbs, and other edible crops.

Because these trays are made from a premium pliable plastic rather than thin, brittle polystyrene, they are designed for multi-season use. With careful handling during transplanting and proper storage away from direct UV light when not in use, these trays can easily last for 3 to 5 years or more.

To prevent the spread of soil-borne pathogens like Pythium (damping off), we recommend washing the trays in warm soapy water to remove debris, followed by a soak in a 10% bleach solution or a specialized horticultural sanitizer. The pliable plastic holds up well to standard cleaning agents without becoming brittle.

You can use both! These trays are excellent for loose soilless seedling mixes. If you prefer a pre-loaded media option, the cell dimensions are perfectly compatible with the Speedy Root 50-Cell starter tray, which includes high-quality propagation media.

The pliable nature of the plastic is a major advantage here. You can gently squeeze the bottom of the cell to "pop" the root ball upward. Alternatively, because these trays fit inside a heavy-duty 1020 flat, you can use a finger to push through the drainage hole at the bottom to slide the seedling out cleanly once the roots have fully knit the media together.
