Modular Planted Floor™ — Starter Kit (9 Free STL Files + PDF Template)

Everything you need to build your first Modular Planted Floor™.

This free starter kit includes:

✦ MPF™ Small — 70 × 70 mm | H30 · H38 · H50

✦ MPF™ Medium — 70 × 140 mm | H30 · H38 · H50

✦ MPF™ Large — 140 × 140 mm | H30 · H38 · H50

✦ PDF slit template — print at 100% scale, do not resize

Three heights, one for every setup:

✦ H30 — 1.2 inches (standard — great starting point for most plants)

✦ H38 — 1.5 inches (more root volume for medium growers)

✦ H50 — 2.0 inches (maximum depth for root feeders and heavy growers)

Not sure which height to use? Start with H30. You can always print an H38 or H50 module later for a specific planting zone without rebuilding anything.

You will need a 3D printer or a friend or shop to print them for you.
