Product Details & Performance
Hortibulk’s commercial 1020 Seedling Plug Trays are essential tools for modern agricultural greenhouses, flower nurseries, and automated propagation facilities. Engineered from high-tensile PET plastic, these trays offer exceptional flexibility and resistance to deformation, allowing workers and automated machinery to handle seedlings smoothly without brittle tray fracturing.
Key Features for Commercial Growers & Wholesale Distributors:
1. Standardized 1020 Footprint
Each tray adheres strictly to standard industry dimensions (~53cm x 28cm). This ensures total inter-brand compatibility with universal 1020 flat carrier trays, bottom-watering sub-irrigation benches, and greenhouse transport racks.
2. Superior Root Architecture & Easy Plug Ejection
Every individual cell is tapered with smooth internal walls and a center drainage hole at the base. This design prevents root circling, encourages healthy taproot aeration, and enables farm operators to pop out intact soil plugs quickly during field transplanting.
3. Scalable Cell Densities for Commercial Crops
- 50 / 72 Cells: Ideal for larger fruiting crops like tomatoes, cucumbers, peppers, and nursery succulents requiring extensive root volume.
- 105 / 128 Cells: Optimized for high-density propagation of leafy vegetables, herbs, and flowering ornamentals where spatial efficiency is paramount.
4. Lower Shipping Costs via High Nesting Density
Designed with precise vertical stacking lugs, these PET trays nest tightly together during transit to minimize volumetric shipping space, drastically reducing ocean freight costs per unit for overseas B2B buyers.
5. Complete 1020 Propagation System Compatibility
To provide a full turn-key solution for commercial growers, we offer matched 1020 Flat Carrier Trays in two configurations:
- Solid No-Hole Trays: Essential for sub-irrigation (bottom watering) techniques and growing fodder or microgreens. Prevents water runoff on greenhouse benches.
- Drained Mesh Trays: Engineered with base drainage holes to support soft plug inserts while allowing rapid water discharge in overhead sprinkler setups.
