Heavy Duty Polypropolene, 40 cell germination tray, reusable, resilient, 350mm x 215mm x 55mm

They are easy to fill and being deeper than most cell trays plants can remain in them for longer. their rigidity means that the cells can be emptied by just pushing up from the bottom. They do not have a bottom in the cell so need to be set in a gravel tray. They can be used over and over again. I ordered more!
