Definition - What does Wick System mean?
A wick system is a watering method for potted plants that uses a soft fabric string known as a wick. One end of the wick is buried in the soil, and the other end hangs into a pot, dish, or bucket of water. Water will flow up the wick and water the plant until the soil surrounding the plant is damp. Once the soil dries out, the wick will again soak up water.

Water is one of the most crucial components to a plant's health and vitality. If plants don’t receive a proper amount of moisture, they will begin to wilt or die off. A wick system is one way gardeners can distribute water to plants.
A wick system works by “sucking” or wicking up water like a sponge and feeding it up to the plant. This process of “sucking” or wicking up water is a scientific principle known as capillary action.
There are several different benefits to watering plants with a wick system. First, wick systems are considered to be one of the easier forms of hydroponic watering, and are thought to be a good tool for gardeners who may be interested in watering their plants with a hydroponic technique. Additionally, wicks allow plants to “soak up” water or nutrients at a slow place.
However, there are a few downsides with using a wick system. The biggest downside to using a wick system is that they generally do not work well with larger plants, and therefore should only be used with much smaller plants or cuttings. In addition, plants that use a wick system need to be flushed out with plain, fresh water once a week to prevent a buildup of mineral salts that may be present in the growing medium.
