Wick Hydroponics
The most basic of hydroponic techniques is the wick. Just as the name implies, this system uses one or several wicks to draw nutrient solution from a reservoir into a sterile medium such as coco coir (ground up coconut skins), peat moss or rockwool. A wick system is cheap and simple to set up and doesn't require any pumps or elaborate drainage systems.Plants grow directly in the medium and take up the nutrients as needed. These systems are ideal for small set-ups such as an indoor hydroponic kitchen garden or collection of house plants. It is not, however, the most efficient delivery system and may not be able to adequately keep up with the needs of large or rapidly growing plants.
