The specific hydroponic cultivation method you decide to go with will have a marked impact on exactly how many plants you are able to fit into any given space. Nevertheless, hydroponics in general enable growers at all levels to position a considerably greater number of plants within the same given area than would be possible with traditional soil growing. This is particularly true in the case of vertical hydroponics, where even a single square metre can be optimised two, three or even ten-times over by positioning plants above one another. All of which means that even if you only have a very limited amount of space to work with, you can still grow an extremely generous number of plants.
