The HC Companies M6 Square Pot | Black/Black - 5in D x 5.37in H - Max Liquid Volume: 1.5qt (Case of 468)

Co-Extruded M6 Square Pot for Bench-Density Root Protection

Round pots leave unused gaps between neighboring containers on a bench, space that a square footprint can put back into production. The HC Companies M6 Square Pot combines that space-saving square shape with the brand's dual-color co-extrusion, keeping a dark interior wall that blocks light from reaching the root zone.

This Black/Black, 5in D x 5.37in H pot holds 1.5qt maximum liquid volume, ships in a case of 468, and pairs with TCS08M60 trays for growers maximizing bench density on automated lines.

Key Features & Benefits

• M6 square footprint — packs tighter against neighboring pots than an equivalent round pot, increasing plants per bench.
• Co-extruded shell with dark core — traps a light-blocking layer inside the wall during forming, so the root zone stays shaded regardless of the pot's visible exterior color.
• Drainage spread across the base — so no single clogged opening leaves water pooling under the root ball.
• Rim built to resist wear from automated handling — so repeated pickup and placement by potting equipment doesn't deform the opening over time.

Who Should Use This

Growers on high-speed automated potting lines who want to maximize bench density with a square footprint, without giving up light-blocking root protection, are the right fit for the M6 Square Pot.

About The HC Companies

The HC Companies extends its co-extruded pot technology into a square M6 footprint for bench-density gains, part of the wider nursery and greenhouse container line it produces out of Twinsburg, Ohio.

Frequently Asked Questions

Why choose a square footprint over a round pot?

A square shape packs tighter against neighboring pots on a bench, since there's no wasted gap where the rounded sides of a circular pot would otherwise leave space. That density gain adds up to more plants per bench for the same floor area.

Why is the interior of this pot dark?

The wall is co-extruded with a dark inner surface formed as part of the same molding step that creates the pot, rather than a coating applied afterward. Keeping light off the growing medium this way helps prevent the algae growth that develops when a wet surface sits in direct light.

What is the maximum liquid volume of this pot?

It's rated to 1.5qt within a 5in D x 5.37in H shell, measured at a full-to-the-brim fill. That's the pot's capacity filled level to the rim, not the smaller working volume left once growing medium and a plant are potted.

How does this pot perform on automated potting lines?

Its rim is built to resist wear from the repeated pickup-and-placement cycles of automated filling equipment rather than manual potting alone. It pairs with TCS08M60 trays for organized bench-scale handling.
