Landmark Plastic Sheet of 18 Round Pots - X-3.5SPWB - 4.51in x 3.53in x 3.00in - Gray

Air-Pruning Sheet of Pots for Transplant-Ready Plants with Superior Root Structure

The Landmark Plastic X-3.5SPWB Sheet of Pots provides 18 connected round pots in a single sheet format. Each pot measures 4.51in x 3.53in x 3.00in D in gray polystyrene. The bi-level drainage system and air-pruning base encourage vigorous root development and prevent root circling, producing transplant-ready plants with well-branched, fibrous root systems.

Key Features & Benefits

• 18 round pots per sheet - Connected sheet format for efficient filling, handling, and production line use.
• Bi-level drainage - Two-tier drainage removes excess water efficiently while retaining adequate moisture for optimal root zone conditions.
• Air-pruning base - Open base design exposes root tips to air, naturally pruning them and stimulating lateral root branching for a dense, fibrous root ball.
• Pot dimensions: 4.51in x 3.53in x 3.00in D - Generous volume supports robust root development before transplanting.
• Gray polystyrene construction - Durable, lightweight, and reusable for multiple production cycles.

Who Should Use This

Propagators and nursery growers seeking air-pruning pot sheets for producing transplant-ready plants with strong, branched root systems. Suitable for vegetable starts, ornamentals, and specialty crops requiring consistent root quality at transplant.

Compatibility

Use with compatible tray carriers or bench systems. Works with peat, coco coir, bark-based, and soilless growing media. Compatible with overhead and flood-floor irrigation systems.

Frequently Asked Questions

What is air pruning and why does it improve plant quality?

Air pruning occurs when root tips reach the open base of the pot and are naturally desiccated by air exposure. This stops downward root growth and triggers lateral branching, producing a denser, more fibrous root ball that establishes faster after transplanting.

What are the pot dimensions?

Each pot in the X-3.5SPWB sheet measures 4.51in x 3.53in x 3.00in D.

How does bi-level drainage work?

The bi-level drainage system uses openings at two distinct levels in the pot wall, ensuring excess water drains freely while retaining adequate moisture for healthy root development.

Are these pots reusable?

Yes - the durable gray polystyrene construction is designed for multiple production cycles with proper cleaning between uses.
