The TS-24F cell tray has been produced in response to interest from New Zealand nurseries growing native seedlings, forestry plantation companies, and leading growers experiencing increasing nursery mechanisation.
It is a multi purpose tray to be used with loose fill growing media or as a holding tray for paper pots up to 50 mm.
The trays are made from HDPE (High Density Polyethylene) virgin resin with UV protection.
The distinction between virgin resins and recycled resins is immensely important. Virgin resins are typically more durable on the molecular level than recycled resins, and they perform better over a longer period of time.
The UV protection helps the TS-24F trays have a long life expectancy of fifteen to twenty years use, in line with other trays produced by Transplant Systems. This is also an important distinction when considering thin trays that are destroyed while removing the plants or fail due to UV degradation in the plastic.
Each cell of the TS-24F has a complex architecture, with a volume of 292 cc. The side slots in the cell are designed for aerial root pruning and easy root ball extraction. The top of the TS-24F tray includes generous air vents to help air flow through the tray and the crop canopy, reducing disease due to lack of air movement, and enhancing the aerial root pruning where the roots are effectively “burned” off, causing the plant to constantly produce new and healthy branching roots.
Due to the squat nature of the cells, planting in the field is greatly enhanced, making it much easier for planting teams to plant quickly without the root distortion common with deep cell trays. (See our article "How deep should a container be for tree seedlings")
The TS-24F tray is designed to be placed on wire mesh benching to take advantage of root pruning, but each cell has a carefully designed media catch grid at the base of the cell, comprising a centre hole with 4 radial holes to assist plant extraction, giving the opportunity to automatically push the seedling out with five pins, unlike other designs, only allowing a single pin that often damages the root ball.
The design of the base of the TS-24F also gives ideal drainage, without recesses accumulating unwanted water, so that the grower retains control of the air porosity of the media
As well as the biological benefits of the TS-24F cell tray, the design and precision incorporates all the modern features required to use it in automatic machinery also supplied by Transplant Systems. The trays are designed to nest, for ease and economical transport, but are also designed to be dispensed by machine, and are robust enough to withstand the soil delivery system of high speed tray filling machines.
When using the TS-24F cell tray for holding 50 mm paper pots all the features designed for loose fill, work to enhance
the root zone, as air movement around and through the paper is improved by the ribs inside the complex cell design. Paper pots can
be placed manually, or can be mechanically delivered to the cell due to the careful design and taper of the cell. The paper
pots will engage the cell at 4 points in the lower part of the cell leaving air space between
the paper walls of the pot and the walls of the cell. Plants that are held over with roots emerging from the paper are still
aerial root pruned due to the overall tray design.
With construction of the TS-24F growing cell designed (a) To improve the root structure thus the quality of container raised plants. (b) To contribute in lowering the cost of plant handling in the nursery, (c) Improve the plant extraction from the cell, while reducing damaged root balls and (c) Long life expectancy, the features of theTS-24F cell tray stack up for better results.
Adding to all these benefits, the TS-24F tray has a common foot print to the TS-48F cell tray allowing the same machinery and the same benching to be used. We know this will help a lot of nurseries already using the TS-48F, as machines need less adjustment when changing from tray to tray, thereby increasing useful production time.
