Aptus PCS P-50 Pot Sock Liner

A Sterile Consumable Liner That Keeps the PCS P50 System Performing Cycle After Cycle

The Pot Sock Liner is the consumable component at the heart of the PCS P50 planting system. It performs three functions simultaneously: it contains the growing medium, provides a mesh base that supports drainage without letting media escape, and allows root tips to penetrate through into the air void created by the Grid below.

Constructed from sterile material to prevent contamination between cycles, the Liner is designed for easy cleaning and a fast reset at the end of each grow. Its construction supports the airflow and drainage characteristics the PCS P50 system is built around.

Key Features & Benefits

• Holds growing media in place — contains the growing substrate within the PCS P50 system throughout the full cycle without slumping or shifting.
• Mesh base increases drainage — allows water to drain freely through the base of the liner without retaining excess moisture around the root zone.
• Allows roots to penetrate the air void — root tips can grow through the mesh into the air void created by the Grid below, supporting natural air-pruning.
• Constructed from sterile material — prevents cross-contamination between growing cycles and supports a clean reset before each new run.
• Easy to clean between cycles — designed for straightforward cleaning and reuse or replacement at the end of each grow.

Who Should Use the PCS P-50 Pot Sock Liner

Growers running the Aptus PCS P50 planting system who need to replace the consumable fabric liner between grow cycles — either as part of a full system reset or as a standalone liner replacement when the rest of the components are still in serviceable condition.

Liner Replacement and Cycle Resets

Replace the Pot Sock Liner at the end of each growing cycle as part of the standard reset procedure. If the rest of the PCS P50 components are in good condition, the Liner can be swapped individually using this SKU. For a full five-component refurbishment including Grid, Base, Ring, and Lock, use the PCS P50 Accessory Kit (AP60052).

Frequently Asked Questions

How does the Pot Sock Liner hold growing media?

It's a form-fitting fabric sleeve that contains the substrate within the PCS P50 pot. The mesh base lets water drain freely while keeping the growing medium contained above it.

When should I replace the Pot Sock Liner?

Replace it at the end of each growing cycle as part of the standard system reset. If the liner shows signs of wear, root penetration damage, or contamination, replace it before the next run even if the cycle isn't complete.

Can the mesh base cause any drainage issues?

No — the mesh base is sized to allow free drainage while retaining growing media. It works alongside the air-void Grid below to support the drainage and root-zone characteristics the PCS P50 system is designed around.

Is the Pot Sock Liner reusable or strictly single-use?

It's designed as a consumable for easy cleaning and fast resets. While it can be cleaned between cycles, Aptus treats it as a replaceable consumable to maintain sterile growing conditions.
