About Hydroponics

Hydroponic gardening is better than soil gardening for several reasons. More plants can generally be grown in the same amount of space when compared to traditional soil gardens. Roots are delivered nutrients instead of having to stretch out in search of them. Also hydroponic gardens can be stacked to further increase space efficiency. The main benefit to hydroponic gardening is much higher oxygen levels in the root zone when compared to a soil garden.
