Aqua Botanic-Laterite substrate |
 | | Laterite is a soil or rock found in the tropics that is very high in iron. |
 | | Laterite is a pedogenic and highly weathered natural material formed by the concentration of hydrated oxides of iron and aluminium. |
 | | Since it is found in the same tropical regions as the plants we use come from, and laterite run off is found in the waters of the tropics, it seems a logical conclusion that laterite is part of tropical plants natural element. |
