Large drain channels

The 1,20m x 2,40m Danish Hydrotray is designed with large drain channels longitudinally and smaller drain channels across. The outside dimensions of the tray are just under 1,20m x 2,40m to fit perfectly in tents and includes a 16cm high sidewall.

On the long and the short end, a smart valve sump is included to keep roots and leaves out of the drain.

Made with the highest quality

The trays are produced with 100% new material of the highest quality. Over the years, the bench trays have been thoroughly tested for use with fertilizers, effects of temperature change, UV radiation and general daily wear in a modern greenhouse. This knowledge is used for continuous improvement and to optimize the products, so that today they represent the industry`s absolute best quality.

Unique design

The unique design of the drainage channels is produced in such way, that the border-effect on the sides of the bench tray is minimized by ensuring a 2 mm higher water level along the edges of the tray. The result is a very uniform culture.

Our quality


The trays normally last 20 years. The advantage of High Impact Polystyrene is mainly the UV-stability. We also added a special UV protector to the topside, so the lifetime is increased as much as possible. The Danish Hydro Tray is chemical resistant and food approved.

Smart design

The tray is designed with large drain channels along the sides and smaller drain channels across. On the 2 edges of the tray we have added a smart valve sump to keep roots and leaves out of the drain.

No border-effect

The unique design of drainage channels is produced in such a way, that the border-effect with a dry culture on the sides of the tray (caused by high evaporation) is minimized, by assuring a 2 mm higher water level and a longer watering time for the plants along the edges.

Strong material

The trays are produced in a material of highest quality. The modern production methods and tools ensure a so far unknown quality and precision of ebb/flow bench trays. These conditions hands the end user a quality product that ensures a problem free, long lifespan.

Danish quality

The Danish Hydro Trays have been manufactured in high impact polystyrene (HIPS) since 1984.
