The trays are made of flute board and have a usable base area of 260mm wide x 520mm long with fold up corners.
The trays are custom designed so that 200 of the Pure Hydroponics 25x25x40mm Rockwool cubes can fit perfectly inside each tray.
The rockwool cubes come in sheets of 80 cubes (4 x rows of 20 cubes).
Therefore 2 and a half sheets of cubes will perfectly fit inside each tray with no wasted space.
The beauty of these fold up trays is that they are lightweight and can be shipped flat and then the corners can be folded up on site to reduce shipping costs.
When not in use the trays can be unfolded, washed and packed away.
The trays have drainage slits in the base to allow for a flood and drain action and removal of run off.
