Product details
The TS-100 is a heavy-duty forestry seedling tray widely used in Australian forestry nurseries for raising hardwood and softwood seedlings and small cuttings. Its square cell geometry and raised internal wall structure deliver effective air-root pruning on all four sides — producing clean, fibrous root plugs and uniform seedlings ready for field planting.
Root Architecture and Air-Pruning Performance
Each square cell features raised internal sections that direct developing roots toward side-slot openings, where they are naturally air-pruned rather than left to spiral or circle. Air pruning on all four sides produces a dense, fibrous root ball that transplants cleanly and establishes quickly in the field.
The cell base includes a media catch web with a central 14 mm diameter hole for plug extraction tooling, and an apex that guides roots and prevents spiralling at the base. Corner air vents (6 mm diameter) improve airflow through the developing leaf canopy, and inter-cell vents allow vertical air movement in high-humidity growing environments — both reducing fungal disease risk.
High-Efficiency Propagation
- 676 plants per m² — delivers 23% more plants per m² than earlier 81-cell trays of the same outer dimension, proven over a three-year production period
- Compatible with 25 mm paper pots — roots penetrating the paper are air-pruned in the space between the paper and cell wall
- Suitable for manual handling and nursery automation — square tray format works with standard filling, seeding, and transplanting equipment
- Robust construction built for repeated nursery cycles
- Well suited to Eucalyptus and other Australian native tree and shrub species

Frequently Asked Questions
What species is the TS-100 suited to?
The TS-100 was designed for high-volume forestry production and performs particularly well with Eucalyptus and other Australian native hardwood and softwood species. It is also suited to woody shrubs, ornamental trees, and any species propagated from small cuttings.
How does the TS-100 achieve 23% more plants per m² than earlier trays?
The TS-100's square cell geometry and tray format allow 676 plants per m², compared to approximately 550 plants per m² for earlier 81-cell trays of the same outer dimension. This efficiency gain was proven over a three-year production period and translates directly to lower cost per plant across nursery, transport, and planting stages.
Can the TS-100 be used with paper pots?
Yes. The TS-100 can carry 25 mm diameter paper pots. Roots that penetrate the walls of the paper are air-pruned in the air space between the paper and the cell walls, maintaining clean root architecture even in this format.
How are plugs extracted from the TS-100?
Each cell base has a 14 mm diameter central hole designed for plug extraction tooling, including compatibility with plug popper machines for manual transplanting operations. The cell taper and side slots also assist clean plug release.
