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.
Read the guideBootstrap Farmer / Seed starting
These reusable six-cell inserts are useful when you want to move small groups of seedlings without committing an entire large tray to one crop. Twelve inserts fit a 1020 tray, allowing batches with different sowing dates to be separated later. The manufacturer specifies polypropylene construction, large 5/8-inch drainage holes and side slits designed for air pruning. The holes also provide access beneath a root plug, but gentle removal and suitable root development still matter. Each insert measures 5 by 3⅓ inches and 2¼ inches high, so check compatibility with trays and shelf space rather than relying only on the 1020 name. The cells are a starting stage, not a promise that tomatoes or peppers can remain there until any outdoor planting date. Choose the pack quantity and color deliberately; the manufacturer offers multiple configurations, and this profile does not equate them to one unverified Amazon listing.
