We use the nursery plant trays 30/40 104 and 30/40 54 made by Teku. The 104 unit is twice as thick as the Teku standard trays, so we can use them repeatedly. Two of these trays go into one crate.
You can collect the trays and return them free of charge. Just put them into the crates and hand them over to the truck driver when he delivers your next delivery.
We clean the trays and use them again.
