72 Cell Seed Starter Tray, 10 Pack Seed Trays with Drain Holes — 2.2 Inch Deep Seedling Plug Insert for Germination Propagation, 720 Cells, 21 x 11.5 Inches, Black

Starting seeds indoors can save weeks during a short growing season. These 72-cell seed starter trays give every plant its own growing space, with individual cells measuring 1.57 x 1.57 inches across and 2.2 inches deep. Each cell is separated by rigid walls that help prevent root entanglement between neighboring seedlings. When it is time to transplant, the separated root balls lift out more cleanly than they would from a shared open flat. The tray layout works for a range of spring and indoor starts: tomato, pepper, broccoli, kale, lettuce, basil, cilantro, marigold, zinnia, and most small-seeded vegetables, herbs, and flowers. Fill each cell with seed starting mix, press in one or two seeds, water gently or from below, and wait for germination. Growers who practice succession planting can start new batches of fast-growing herbs every few weeks using separate trays. Every cell has a drain hole at the base. Excess moisture drains downward rather than pooling around the roots. If you use a bottom-watering method, place the insert inside a drip tray or flat tray that can hold water beneath the cells. Each tray measures 21 x 11.5 x 2.2 inches overall. If you plan to place this insert inside an existing flat tray, please measure the internal dimensions of your flat before ordering to confirm fit. The insert also works placed directly on a tabletop, shelf, windowsill, or any waterproof surface. A 10-pack provides 720 cells total — enough to start a full home garden from seed, to sort different varieties across separate trays, or to dedicate an entire tray to a single crop. After the season, rinse the trays with water, allow them to dry, and stack them flat for storage.

• [Drain Hole in Every Cell] Each of the 72 cells has a drain hole at the bottom, allowing excess water to exit rather than pooling around roots. Works with bottom-watering setups when placed inside a compatible drip tray.
• [Plastic Construction] Made from plastic with structured cell walls that hold shape when filled with moist soil. After each growing cycle, rinse with water, dry fully, and stack flat for compact off-season storage.
• [Overall Tray: 21 x 11.5 x 2.2 Inches] Please measure your existing setup before ordering to confirm this insert fits your flat tray. Also works as a standalone tray on any waterproof surface such as a table, shelf, or rack.
