Gro Pro 5 x 5 x 7 in Square Plastic Pot Black (4480/PL)

The Gro Pro 5 x 5 x 7 in Square Plastic Pot is an injection-molded container made from high-grade polypropylene. At 5.0" L x 5.2" W x 7.2" H with a volume of roughly 0.108 cubic feet, it is sized for seedlings, young transplants, and compact finished plants. The square footprint tiles efficiently on benches and flood tables, reducing wasted grow space. This pot is sold in pallet quantities (4,480 units per pallet), making it well-suited for commercial operations that need consistent, uniform containers at scale.

Why Choose the Gro Pro 5 x 5 x 7 in Square Plastic Pot

This pot addresses a common set of trade-offs in commercial container growing: cost, uniformity, and physical durability. Here is what the canonical product data supports:

• Injection-molded construction: The injection-molding process produces consistent wall thickness across every unit in a pallet run. This matters in large facilities where uneven pots cause handling problems on automated transplant lines.
• High-grade polypropylene: Polypropylene resists cracking under repeated bench-handling and stands up to standard fertilizer and disinfectant concentrations used between crop cycles. It is also light enough at 0.4 lb per unit to keep overall bench load manageable.
• Durable and versatile design: The manufacturer describes these pots as durable and versatile — a claim grounded in the polypropylene material choice and injection-molded form. They can move between greenhouse, indoor grow room, and outdoor nursery environments without special handling.
• Square footprint for bench efficiency: Square containers pack wall-to-wall on flood trays and benches with no wasted gap between pots. Compared to round containers of similar volume, square pots typically allow higher plant density per square foot of bench space.
• Pallet-quantity pricing: The 4,480-unit-per-pallet format is designed for commercial buyers who need consistent supply at a known per-unit cost. Ordering at pallet scale reduces per-unit cost and simplifies inventory.

Best Uses for the Gro Pro 5 x 5 x 7 in Square Plastic Pot

The 5 x 5 x 7 in size and square form factor suit a specific range of growing applications. Use cases below are derived from the product category (Growing Media & Containers — Pots, Saucers & Fabric Containers) and the physical attributes.

• Seedling and early vegetative stage: The 0.108 cu ft volume is appropriate for germinated seedlings and rooted cuttings transitioning out of propagation trays. Plants can establish in this pot before being transplanted to a larger container.
• Compact finished crops: Herbs, lettuce, microgreens, and other short-cycle crops can be grown to harvest in this pot size without transplanting. The 7.2 in height provides enough root depth for most annual herb varieties.
• Flood-and-drain (ebb and flow) systems: The square base sits flat and stable on flood tables. The pot volume is small enough to flood and drain quickly, which is an advantage in high-frequency irrigation schedules.
• NFT and channel systems: Square pots can be seated in channel lids cut to match, holding the pot securely while roots extend into the nutrient stream below.
• Nursery and propagation operations: At 4,480 units per pallet, this pot is practical for high-throughput nurseries that propagate large quantities of cuttings or seedlings and need a uniform container for sorting, labeling, and shipping.
• Paired with fabric pots for staged growing: Some operations start plants in rigid plastic pots and move them into larger fabric pots like the Smart Pot 3-gallon as they enter the vegetative stage. The rigid plastic pot at propagation stage is lower cost and easier to clean between batches.

Compatibility

This pot is a general-purpose rigid plastic container and is compatible with a wide range of growing systems and media. The following compatibility notes are based on the physical attributes and material properties from the canonical data:

• Growing media: Compatible with coco coir, perlite blends, lightweight soilless mixes, and expanded clay aggregate (hydroton). The volume is too small for deep-rooted crops that require more than approximately 0.1 cu ft of root zone.
• Irrigation methods: Hand watering, drip irrigation, flood-and-drain, and sub-irrigation are all workable with this container. The pot size is suited to high-frequency, low-volume irrigation schedules.
• Grow systems: Fits standard 10×20 propagation trays and most commercial flood tables designed for small containers. Verify channel or tray slot dimensions before ordering if using in a specific system configuration.
• Disinfection: Polypropylene tolerates standard greenhouse disinfectant solutions including hydrogen peroxide-based products and dilute bleach. Avoid prolonged exposure to high-concentration bleach or chlorinated solvents, which can degrade polypropylene over time.
• Saucers: Standard square saucers sized for 5 in pots are compatible. If you are managing a larger media setup, a Smart Pot 20-gallon may be more appropriate for mature plants that have outgrown this container size.
