Danish Hydro Tray 4' x 8' by Danish Hydro Tray

Danish Hydro Tray 4' x 8'
Starting at £3.60

The fundamental principle of hydroponics relies on fertilized and aerated water which provides both nutrition and oxygen to a plant's root zone. Because of this, Danish Hydro Tray is only using the best, 100% food approved materials for the production of the trays.

The Danish Hydro Trays have been manufactured in the best quality high impact polystyrene since 1984. Over the years the trays have been thoroughly tested in connection with fertilisers, the influence of fluctuating temperatures, Ultraviolet radiation, and ordinary day-to-day wear in modern greenhouses.

The following optional accessories are sold seperately:

Quick valve for filling and draining

  • The Quick Valve is the answer to many growers' wish for reducing the drainage time and so improving the control of plant and root growth. The Quick Valve is equipped with a separate drainage device, functioning as a siphon. Consequently, the drainage time is reduced with up to 80% compared to traditional ebb/flow systems. This valve has a very high reliability without moveable parts. During the filling process the Quick Valve oxidizes the nutrient solution with air being sucked in, due to underpressure. The draining capacity of each Quick Valve is about 7.4 gallons per minute (28 litres per minute), untill the siphon stop -i.e. when the table is nearly emptied for nutrient solution. The rest will run off the table without using the siphon impact.

Glue

  • We have developed a special glue for extending the Danish HydroTrays and to make sure they are water tight.
    DO NOT use an excessive amount of glue. This can damage the trays. For further information about the use of this special glue please read the instruction carefully before use. The plastic filter can be bought together with the Danish Hydro Trays. It prevents blockage of valves caused by dirt or roots.

Plastic Filter

  • The plastic filter can be bought together with the Danish Hydro Trays. It prevents blockage of valves caused by dirt or roots. The filter is designed so that the top rim is levelled with the bench tray top. This way pots can be placed directly on top of the filter so the whole area of the tray can be utilized.

Rubber Stopper

  • When drilled holes for valves are not used anymore, just use one of the rubber stoppers to close the hole.

Sump Cover

  • If the sump is not used, a sump cover can be glued over the sump. The sump cover is designed so that the top rim is levelled with the bench tray top. This way pots can be placed over the whole area of the tray.
