& frequently asked questions

Which type of tray
is best?

The choice of tray is made in the light of the variety of young plants, and also depending on the desired density. We have many different types of propagation trays, some of them multi-purpose, while others are more specific. We design our seedling trays to meet the plants' agronomical needs: optimisation of germination, and enhanced plant development after transplanting. The cell shape and peat volume are key criteria for obtaining optimum root development and avoiding root circling, etc.

Don't hesitate to contact us for more detailed advice or to set up a test system. It is to be noted that the choice of tray often depends on your market, the climate, the cultivation method (organic or conventional), and also on your facilities.

What will it be used for ?

The vast majority of the trays in Euro format (60 x 40 cm) are used to grow young vegetable plants, whereas trays in Danish format (54 x 30 cm) are generally used in the horticultural industry (flowers). This is mainly due to production and logistics constraints linked to each of these fields. Thus Euro trays are better suited to the market gardening sector, because they are more suitable for seedling and transplantation machines, and also for logistics on pallets (Euro). Trays with legs, known as horticultural trays, are ideally suited to growing young ornamental plants, or transplanting in pots, and also to delivery on Danish roller racks. Their legs also give the young plants plenty of air, avoiding runner roots.

How are deliveries
managed ?

SPID gives priority to long-term solutions rather than throwaway solutions, ecology rather than waste, and reusability rather than disposable resources. Seedling trays constitute a production tool for young plants that is fully suitable and efficient. Nonetheless, efficient, cost-effective logistics solutions are necessary to deliver young plants, in order to comply with the following cycle: production, delivery, cleaning, production... And that's why SPID offers crates, Tray Transporters and growing media. Logistics on growing media or Tray Transporters, or in crates, is recommended for all deliveries, except over long distances, which can be dealt with using inserts.

The long service life of our products is a strength, as compared with thermoformed or polystyrene trays, because the cost savings (after X production cycles) enable you to amortise your production tool quickly and develop your activity.

Why should
I opt
for SPID ?

SPID trays are made up mainly of virgin polypropylene, anti-UV products, and colourant. The quality of the materials selected ensures that SPID products have a very long service life (more than 15 years). Furthermore, when designing its trays, SPID takes into account agronomical constraints (root development), mechanical constraints (seedlings, transplantation, loads, etc.), and also logistical constraints (standards, cleaning, etc.).

To sum things up,
SPID trays are :

  • Anti-UV treated for longer service life.
  • Ecological: Reusable, recyclable polypropylene trays.
  • Smooth for full cleaning and disinfection, homogeneous cell filling and easy removal of young plants.
  • Ideally suited to robotisation and transplanting systems.
  • Identifiable to ensure traceability via bar codes / RFID labels / QR codes, etc.
  • Specially designed to provide young plants with greater uniformity, and which thrive after transplanting.
  • Stackable or nestable, our trays enable mixed deliveries or deliveries in CC roller racks and make your logistics far simpler.
