Detailed explanation-3: -The six things needed are light, air, water, nutrients, heat and space. Hydroponic growing can be done indoors or outdoors. In either setting, plants will need five to six hours of light per day, access to electricity and an area that is level and without excessive wind.
Detailed explanation-4: -All nutrients and fertilizer required for plant growth are mixed into water, which passes through the medium several times a day. An active hydroponic system uses a pump to move water, while passive systems rely on wick or the medium’s ability to absorb water.
