For wholesale plug trays, choose the tray footprint to match your benches, irrigation setup, and handling system, then select a cell count based on the crop’s root space and the time it will spend in the tray. A common nursery format is the 10 × 20 in tray, approximately 25.4 × 50.8 cm, but dimensions and compatibility can vary by supplier. Lower cell counts generally provide more growing space per plant, while higher counts help produce more seedlings in the same footprint. Before ordering, confirm the tray’s external dimensions, cell count, cell shape and depth, material, and fit with any existing equipment.

This guide is for nursery operators, commercial growers, garden supply distributors, and procurement teams comparing plug trays for wholesale purchase. It is useful whether you are replacing trays already in use or planning a new propagation program. The goal is to help you define the specifications to request, rather than suggest that one tray size suits every crop. Final selection should be checked against your growing conditions and handling workflow.
A plug tray is a divided container used to propagate seeds or young plants in individual cells. Its overall size describes the tray’s footprint, while its cell count tells you how many planting spaces it contains. For example, a tray with 72 cells holds fewer plants per tray than a 288-cell tray, but each plant typically has more room than it would in a higher-count tray of a similar footprint.
Cell count alone does not describe usable root space. Cell width, depth, shape, taper, and volume all affect how the growing medium fits and how the root plug develops. Two trays with the same number of cells may differ in these details, so ask for a drawing, specification sheet, or physical sample when exact fit matters.
Wholesale plug trays are available in a range of cell counts. The following examples are common options to discuss with suppliers, not a universal standard; availability and dimensions vary by product line.
| Example cell count | General consideration | Potential fit |
|---|---|---|
| 50 cells | Fewer, typically larger growing spaces per tray | Plants that benefit from more room or a longer nursery stage |
| 72 cells | A moderate plant count for each tray | Production where plants need more space than a high-count format may offer |
| 128 cells | More planting spaces in a comparable footprint | Seedling programs balancing tray efficiency with root space |
| 200–288 cells | High plant count, with smaller cells in many formats | Compact seedlings and operations prioritizing plants per tray |
These examples describe cell counts, not guaranteed cell dimensions or crop suitability. A 200-cell tray from one supplier may not match another in footprint, depth, or cell volume. Compare the full specification before treating two trays as interchangeable.
Plastic plug trays are widely used in propagation, with construction and thickness varying by product. Some are designed for repeated handling, while lighter formats may be selected for a different balance of cost, weight, and use. Do not assume that a tray is reusable, recyclable, or compatible with a particular sanitation routine based on appearance alone; ask the supplier for material details and care guidance.
When comparing options, consider how trays will be filled, watered, moved, cleaned, stored, and discarded or reused. The best material choice depends on your operating process and local waste-management options. If trays must run through automated equipment, confirm the construction and dimensions with the equipment requirements.
Start with the crop’s expected size at transplant and the length of time seedlings will remain in the tray. A longer propagation period or a plant that develops a larger root system may require more growing space than a fast-turnaround, compact seedling. Crop variety, growing conditions, and transplant timing also influence the decision, so use production records or a small trial where possible.

Next, consider the number of plants you need per bench, shipment, or production cycle. Higher cell counts can increase the number of seedlings held in a tray footprint, but smaller cells may require closer attention to irrigation and timing. Lower counts can reduce the number of plants per tray while providing more space per cell. Evaluate the trade-off using your actual crop and labor requirements rather than cell count alone.
Measure the available bench or carrier space and compare it with the supplier’s external tray dimensions. Confirm whether trays need to fit existing bottom-watering systems, inserts, carts, seeders, or transplanting equipment. Even a small difference in outside dimensions or tray rigidity can matter in a closely fitted workflow.
Also check stacking and storage needs, including whether empty trays nest or stack in the way your facility requires. For shipping, compare the packed tray dimensions and quantities with your storage and freight plans. Ask the supplier to clarify whether quoted dimensions refer to the outside of the tray, the cell opening, or another measurement.
This process helps turn a broad request for “plug trays” into a product specification that suppliers can quote consistently. If you are comparing several options, use the same criteria for each one. That makes differences in fit, cell design, and service easier to assess.
Wholesale pricing can depend on tray design, material, order volume, packaging, and destination. Minimum order quantities and production lead times also vary by supplier and product, so they should be confirmed for the specific specification and order date. Rather than relying on a general estimate, request a written quotation that identifies the product, quantity, packing details, delivery terms, and any tooling or customization charges that apply.
If you are considering a custom format, ask whether the supplier can support the requested footprint and cell design, and what information is needed to assess feasibility. Customization may affect minimum quantities, cost, and timing. Keep standard and custom options in the same comparison so you can assess the trade-offs before committing.
A useful supplier conversation should resolve practical questions, not just confirm a cell count. Share your crop, equipment constraints, annual or seasonal purchasing plan, and destination market. This gives the supplier context to identify suitable options and flag details that need verification.
The right wholesale plug tray is the one that matches your crop’s root-space needs and your operation’s footprint, equipment, and purchasing requirements. Use cell count as a starting point, then compare the full cell geometry, tray dimensions, material, and handling characteristics. Common formats such as 10 × 20 in and example counts such as 50, 72, 128, or 288 cells can help frame an inquiry, but supplier specifications determine actual compatibility.
Before placing a bulk order, prepare a short specification brief with your intended crops, target cell count, required outside dimensions, equipment constraints, material preferences, quantity, and delivery location. HORYARD can discuss wholesale plug tray requirements and help buyers evaluate available specifications and sourcing options. Contact our team with your brief to request a product discussion and quotation; confirm samples or drawings against your workflow before final approval.
