Pro Cal Premium 3.5 inch Square Pot with tag slot (Case of 832)

A Small-Format Square Pot for Propagation and Bench Production, 3.5in

Propagation and early-stage bench production call for a different pot than a long-term container: growers need a small, uniform footprint that packs tightly on a tray, with drainage that keeps young root systems from sitting in standing water. The Pro Cal Premium 3.5 inch square pot is injection molded with bi-level drainage holes positioned at two heights on the sidewall and base, so water moves out of the pot consistently even when trays are packed edge to edge.

This 3.5 inch pot measures 3.37 by 3.37 inches at the outside diameter and stands 3.93 inches (9.98 cm) tall, with a molded-in tag slot for plant identification, and ships in a case of 832 for growers filling out full propagation benches.

Key Features & Benefits

• Bi-level drainage holes — positioned at two sidewall heights plus the base for consistent runoff in a small pot
• Molded-in tag slot — holds a plant tag or label directly on the rim for identification across large propagation runs
• Injection molded construction — gives thicker, more uniform walls than a blow molded pot of the same size
• Compact 3.37 x 3.37in footprint — packs tightly on a standard propagation tray or bench
• Sold in a case of 832 — for growers outfitting full propagation runs at commercial scale

Who Should Use This Square Pot

Commercial propagators and bench growers running large batches of small starts, cuttings, or young plants that need to be labeled and tracked will benefit from this pot's compact size, drainage, and tag slot.

Frequently Asked Questions

What size is this pot?

This listing is for the 3.5 inch square Pro Cal Premium pot, measuring 3.37 by 3.37 inches at the outside diameter and standing 3.93 inches (9.98 cm) tall. That compact footprint is sized for propagation trays rather than long-term container growing.

How many pots come in a case?

This pot ships in a case of 832, sized for commercial propagation runs rather than small retail quantities. Buying by the case keeps per-pot cost down for large batches.

What does bi-level drainage mean?

Bi-level drainage means the pot has drainage holes positioned at two different sidewall heights in addition to the base. Water continues to move out of the pot even in a tightly packed tray, where airflow around a single row of base holes might otherwise be limited.

What is the tag slot for?

It's a molded-in slot on the rim that holds a plant tag or label in place. It lets growers track variety, batch, or planting date across a large propagation run without a separate stake.

How should I use this pot in a propagation setup?

Fill the pot with a propagation-grade soilless mix, then insert a rooted cutting or seedling and place it on a standard tray. The bi-level drainage keeps the small root zone from sitting in standing water while the compact footprint lets multiple pots pack tightly on the same bench space.
