Wick System
The Wick system is by far the simplest type of hydroponic system. This is a passive
system, which means
there are no moving parts. The nutrient
solution is drawn into the growing medium from the reservoir with a
wick. Free plans for a simple wick system are available (click here for
plans).This system can use a variety of growing medium. Perlite, Vermiculite and Coconut Fiber are among the most popular. The biggest draw back of this system is that plants that are large or use large amounts of water may use up the nutrient solution faster than the wick(s) can supply it.
