Jiffy, offered by Ferry-Morse / Seed starting
Jiffy Seed Starting Kit, 72 cells with 36mm peat pellets
The Jiffy J372PROGS kit combines seventy-two expandable, thirty-six-millimeter peat pellets with a watertight base tray and clear humidity dome. It suits a seed-starting workflow built around individual plugs rather than measuring loose medium into many cells. Ferry-Morse identifies this pellet size for herb and flower starts and describes the current netting as derived from cornstarch. The large pellet count is useful for organizing a batch, but it also means planning labels, space under lights, and room for the plants as they develop. Treat the dome as one part of the early-stage setup and follow the supplied instructions for its use. This is the seventy-two-pellet, thirty-six-millimeter version, not one of Jiffy's larger-pellet kits with a different count.

Tradeoffs & verification notes
Thirty-six-millimeter pellets provide early growing space, not permanent containers; some crops will need an intermediate pot before planting out.
The kit is peat-based and therefore unsuitable for a deliberately peat-free setup.
A humidity dome does not provide growing light or controlled bottom heat, and its use needs to change with the seedlings' stage.
Cornstarch-derived netting does not justify a universal decomposition-time promise; follow the current transplant instructions.
