With this method of gardening, the needed nutrients are dissolved in water, and directly supplied to the plants' roots. The organic nutrients must be soluble enough so that the roots can easily drink up the solution.
Most hydroponic gardens are contained in some sort of greenhouse. Some greenhouse gardeners worry that the hydroponic method could be ecologically harmful and bad for the environment, but according to many experts who study the science of hydroponics, this is not the case, and indeed, it can be a great way to produce more food in countries where the food supply is limited.
This is especially helpful because organic hydroponics allows the plant to maintain health and grow more quickly. It may also increase crop production in some cases.
