Their high and square shape is adapted to taproot plants (rose bushes, climbing plants, berry trees, etc.). Their shape also allows the optimization of the loading of the rolls CC and the number of pots per m². The 2L version is narrower to optimize the loading of CC rolls. The reinforced rim of the containers of this range is very rigid for a perfect machine de-stacking. Their 4 slots allow a secure fixing of the labels, the stakes and the carrying handles.
