Hydroponics definition

''A method of growing plants in water rather than in soil.''



3 different types of hydroponic systems

type 1 ''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''


Type 2 The water culture system is the simplest of all active hydroponic systems. The platform that holds the plants is usually made of Styrofoam and floats directly on the nutrient solution. An air pump supplies air to the air stone that bubbles the nutrient solution and supplies oxygen to the roots of the plants.


Type 3 The Ebb and Flow system works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir. This action is normally done with a submerged pump that is connected to a timer.

3 advantages and disadvantages

Advantages of a soilless system include having no soil structure or texture to maintain, no weeds, no raking, no soil-borne pathogens, no need to water, no moles, no cutworms, and the biggie: specific nutrients can be made available to specific plants immediately only when, and if, they need it. The latter is what really supports the claims of bigger plants’ increased yield and higher nutritional value.

Disadvantages of using a soilless system include having to maintain the balance of nutrients in the solution, pH monitoring, pump maintenance, and a high initial cost. These disadvantages are being overcome with automation, human ingenuity and commercialization.
