Standard 1020 flats, cell inserts, humidity domes and nursery cans — the plumbing of seed starting, and the part where cheap gear costs you a whole batch.

Cell size sets how long a seedling can sit before it stalls. 72-cell trays are right for lettuce, brassicas and flowers that transplant early; 50-cell or 4-inch pots suit tomatoes and peppers that will be indoors for six to eight weeks.

Look for whether a tray has drainage holes at all, and whether the flat underneath is rated as heavy-duty — a standard 1020 will flex and dump a full tray of wet cells the first time you lift it one-handed.
