Seed Tray Sizing and Potting On: Plan for the Plants, Not Just the Cells
Choose seed containers by crop, growing time, drainage, and shelf space, then recognize when seedlings need more room.

Burpee SuperSeed 36-cell seed-starting tray
The Burpee SuperSeed 36-cell tray is a reusable loose-mix system built around flexible food-grade silicone cells. Instead of pulling a seedling out by its stem, the design allows the cell to be pushed from below to help release the plug. Corner drainage slots work with a separate watering base that has side handles for moving the tray and pouring off excess water. Alphanumeric row labels and the included Plant-o-Gram offer a practical way to track several varieties in one sowing. Burpee lists top-shelf dishwasher cleaning, which may suit a repeat-use routine. Choose this format when you want to select your own starting medium and reuse the cells, while planning enough light, growing space, and later transplant capacity for the seedlings.

Tradeoffs & verification notes
Cells and a watering base do not supply growing medium, seeds, appropriate light, or crop-specific temperature control.
Thirty-six starting positions do not establish how long each crop can remain in its cell; plan later potting or transplanting.
Drainage channels do not make accumulated tray water self-managing; inspect moisture and remove excess as needed.
Dishwasher compatibility is specified for the top shelf, not every cleaning temperature or placement.
