Power is essential to mans life, I would not imagine a life without light. To man it produces food , comfort and add up beauty to life. As well as to animals and plants. We do need light for the improvements of our way of living. And as time pass by, with the help of research and study, a new technology for lighting needs was born and was called hydroponic systems, that became so popular in many ways. Like of helping plants to grow healthy, acting as the sunlight to plants that needs the nutrients of the sun. The art of hydro had gone too far, probing effectiveness and productivity to life.
I remember a movie were in the actor built his own laboratory underground his house. Plants were cultivated and took care with the help of hydroponic system. And those plants are as healthy like of those plants that are directly receiving heat from the sun. Just amazing how this hydro can make life even more better.
