Choose a plastic plug tray by matching its cell size, depth, drainage, material, and handling requirements to the crop and the stage at which you plan to transplant. Fine-rooted, quick-turn crops may suit higher-cell-count trays, while crops that stay longer in the nursery or develop larger root systems often need more growing volume per plant. At HORYARD, we recommend starting with the crop and production process—not choosing a tray by cell count alone—and checking the exact tray dimensions and cavity volume before ordering.
There is no single plug tray that works best for every crop or nursery system. The right choice also depends on sowing equipment, irrigation, greenhouse space, transport, and whether trays will be reused. Use the steps below to narrow your specifications and prepare a more accurate supplier inquiry.
Begin by listing the crops you intend to propagate and the stage at which each will leave the tray. A seedling intended for an early transplant may need a different root-zone volume from one kept in the nursery longer. Consider the crop’s seed size, expected seedling size, root growth, and sensitivity to root disturbance. These factors help you decide whether to prioritize a compact tray or more space per plant.
Leafy greens and many brassicas are often grown in relatively high-cell-count formats when the production plan calls for compact seedlings and a short nursery phase. A 200-cell tray, for example, provides more planting positions than a 72-cell tray of comparable outer dimensions, but each cell will generally have less space available. Confirm the actual cavity volume and depth with the supplier because cell count alone does not define growing capacity.
Tomatoes, peppers, and herbs can require more consideration of seedling size and time in the tray. If seedlings are likely to remain in the nursery longer, compare a lower cell count or a larger-volume cavity with a denser format. Cucurbits and other crops that develop larger seedlings may also benefit from more room, depending on the transplant stage and growing method. These are starting points for evaluation, not fixed rules for every cultivar or facility.
Cell count describes how many cavities are in a tray, but it does not tell you how much substrate each plant receives. Two trays with the same cell count can differ in cell shape, depth, wall angle, and volume. Ask for the cavity volume in milliliters and the tray’s overall length, width, and height in millimeters when comparing products.
Formats such as 72-cell, 128-cell, and 200-cell trays are useful examples for discussing density with a supplier. A 72-cell tray may offer larger individual cavities than a 200-cell tray when their outside dimensions are similar, but this should be confirmed from the product drawing or specification sheet. Make sure the quoted configuration reflects the exact model you intend to buy, rather than assuming that a cell count determines cavity size.
Depth matters alongside volume. Deeper cavities may be worth assessing when seedlings need a taller root zone, while shallower profiles may better suit particular handling or space constraints. Check how the cavity shape affects substrate filling, root-ball formation, and removal at transplanting. If these outcomes are important to your operation, test the tray with your own substrate and equipment before committing to a large order.
Evaluate the tray in the context of your watering method. Review the drainage openings and cavity design, then consider how water moves through the substrate under your routine. Tray design alone cannot guarantee a particular moisture level, because results also depend on substrate, irrigation volume, greenhouse conditions, and operating practice.
Compatibility with nursery equipment is equally important. Confirm outer dimensions against seeders, filling equipment, benches, carts, and any tray-handling or washing systems you use. Check whether the tray can be stacked and transported in the way your team expects. If you currently use another model, share its dimensions and a sample or drawing with the supplier to help clarify the required fit.
Plastic plug trays are available in different materials and constructions, and product properties vary by design. Rather than selecting a material based only on a general label, ask the supplier to identify the material used for the specific model and explain any relevant care or handling recommendations. Consider exposure to sunlight, handling frequency, cleaning methods, and storage conditions in your operation.

If trays will be reused, assess whether their construction suits your cleaning and handling process. Inspect sample trays for consistent cavities, smooth edges, drainage openings, and stacking behavior. Ask how the supplier manages product specifications across repeat orders, especially if you need the same dimensions or material in future purchases.
For single-season or limited-use programs, purchase price may be a larger consideration, but fit and performance still matter. A tray that does not work with your seeder or bench can create additional handling work, regardless of its unit price. Compare the total procurement requirements, including packing, shipping volume, and replacement planning, rather than relying on price per tray alone.
Estimate how many trays you need for sowing, production scheduling, and any buffer stock you plan to maintain. Then confirm available configurations, minimum order quantities, packaging, and lead time with the supplier. These terms can differ by product and order, so request them directly instead of assuming that a standard tray is immediately available in every specification.
When evaluating a supplier, ask for a product specification sheet or drawing that states the cell count, outer dimensions, cavity volume, material, and drainage details. Clarify whether the product is a standard model or a customized design, and confirm the sample and approval process if applicable. For export purchasing, also discuss packing method, order quantities, and shipping arrangements early enough to support your production calendar.
For mixed-crop operations, build a simple specification table before requesting a quote. Record the crop group, target transplant stage, preferred cell count, required cavity volume, tray dimensions, equipment constraints, and expected reuse needs. This makes it easier to identify where one tray can serve several crops and where separate formats may be more practical.
When possible, compare shortlisted samples under your normal nursery workflow. Observe filling, sowing, irrigation, seedling handling, and transplanting rather than judging the tray by appearance alone. Keep the agreed specification with your purchasing records so that repeat orders can be checked against the same requirements.
At HORYARD, we work with B2B buyers seeking plastic plug trays for nursery propagation and garden supply programs. We can discuss crop mix, desired cell format, dimensions, material requirements, order quantity, and destination when helping you identify suitable product options. Sharing your current tray specification or equipment constraints can make that conversation more precise.
Before requesting a quotation, prepare the crop list, approximate order quantity, preferred tray dimensions, and any sample or drawing you already use. Ask us to confirm the available product details, packaging, minimum order, and lead time for the specific configuration. This information helps both sides assess fit before you move forward with a purchase.
The best plastic plug tray for your operation is the one that fits the crop’s root and transplant needs while working with your irrigation, equipment, handling, and purchasing requirements. Start by comparing cell count, cavity volume, and depth, then verify material, drainage, dimensions, and reuse expectations. Examples such as 72-cell, 128-cell, and 200-cell trays can help frame the discussion, but the final choice should be based on the exact product specification and your growing process.
Your next step is to create a short list of crop requirements and send it with your target quantity and equipment details to a supplier. If you are sourcing plastic plug trays for a nursery or distribution program, contact HORYARD to discuss available specifications and request the information you need for a considered purchase.
