What the 128-cell grid supports

The Bootstrap Farmer 128 Cell Seed Starting Trays give a 1020 shelf a fine plug grid. That layout helps gardeners start a broad group of seedlings, cuttings, or propagation pieces in one tray footprint.

The tray works well when labels, notes, and watering checks stay close to the shelf.

The cells need careful filling

Each cell is 1 inch square and 2.25 inches deep. A light seed-starting mix, a gentle fill, and clear labels help the tray feel easy to manage.

The drainage holes let water move through the grid into a base tray during watering.

A five-pack supports staged sowing

Several trays make it easier to keep rounds separated by date, crop, or shelf position. A simple note card beside the tray can keep the whole plan readable.
