Bootstrap Farmer 6-Cell Plug Tray Inserts

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.

Tradeoffs & verification notes

Larger or long-held seedlings may require potting on.

An outer tray or suitable support is a separate component.

Pack counts and colors vary; the 12-pack multicolor selection excludes pink.

Drainage and air-pruning features do not replace careful moisture management.

Our research standard

This profile summarizes published product information. It is not a hands-on review, an independent durability test, or a guarantee of performance. We prefer an explicit limitation to an unsupported score.
