The modules can communicate with each other, sharing moisture / nutrients, increasing airflow to enhance plant respiration, allowing soil-borne animals / insects to travel between modules, etc. A rooting channel and / or a scalloped sidewall allow the roots of plants in the module to extend to adjacent modules. Alignment notches in sidewalls facilitate alignment of rooting channels between adjacent modules. Vertical zones help facilitate placement of abutting modules flush with each other. The rooting channels may be formed at the vertical zones to enhance continuity between and among modules. Sheet inserts can control rooting between modules and restrict undesired spillage through rooting channels (temporarily if biodegradable). Module inserts help control the quantity and depth of growth media, affecting module weight and rooting levels.

The above-ground part of the low cadmium accumulation type celery cabbage can reject the absorption of the cadmium in the cadmium enriched polluted soil, and the root can fix and adsorb the cadmium in the soil, so that the cadmium is prevented from being transferring upward to the above-ground part. The above-ground part of the celery cabbage is safe to be eaten or sold, and the root is carefully treated, so that the safety of the vegetable food is ensured, and the inedible part(the root) can also be used for fixing and adsorbing a large amount of cadmium in the soil; and by repeatedly planting the vegetable, the excessive cadmium in the polluted soil can be continuously removed, and the cadmium content in the edible part of the celery cabbage also meets the standard of the green safe vegetable. The technology has the advantages of low cost, no damage to physical-chemical properties of the soil, no secondary pollution, the realization of the combination of vegetable-planting and cadmium-removal in the polluted soil and the like.
