Which of the following is NOT true about wick systems?

Wick systems are a type of passive hydroponic system known for their simplicity and efficiency in growing plants without the need for complex technology. They function through a capillary action mechanism that draws nutrient solutions from a reservoir into a growing medium via a wick.

The statement that wick systems require electricity is not true. One of the defining features of wick systems is that they operate without the need for pumps or electric components, making them an ideal choice for beginners and for those looking to create a low-maintenance growing environment. This absence of electricity usage emphasizes their simplicity and the ease with which they can be set up.

Wick systems are indeed considered simple hydroponic systems, suitable for smaller plants that require less water and nutrient flow. They utilize a growing medium, which not only supports the plant but also aids in the transport of nutrients from the reservoir to the plant roots through the wicking action.
