Grow tray 75x100
The Duma tray is a popular system for all kinds of growing techniques but especially rock-wool slabs. A 100cm x 75cm tray is perfect for 4 rockwool slabs with 5 plants in each slab. An equally successful technique is using 12-11 7lt square pots with soil and sprinkler system. Trays can be mounted on a frame and drainage can be connected in series using PVC pipe and fittings, making flushing an ease.These trays can also be used in an Ebb & Flood system.
