What are the different types of hydroponics?
While the traditional, soil-based growing system still has a lot to be said for it, there is growing interest in the hydroponic system of growing plants without soil, since it offers huge space-efficiency and maximum control over growing conditions. It also removes the threat of soil-based pests. In terms of marijuana growing, there are 6 main types of hydroponic growing systems in use.
The Wick System
This is the simplest, possible type of hydroponic system. Essentially the plants are put into growing medium as normal but this is placed on top of a tank of nutrient-rich water with a wick or wicks to deliver this water to the plants. The disadvantage of this system for weed growers is that some strains may be too demanding of nutrients for the wicks to keep up.
The Water Culture System
In this system, the plants are held on some kind of floating platform with their roots in nutrient-rich water. An air pump feeds into an air stone, which keeps the water bubbling and the plants fed. This system is great for quick-growing, smaller plants, but is generally unsuitable for longer-term, larger plants.
