Hydroponics, comes from the Latin language literally translating to “water working”, there are 6 commonly used methods when growing hydroponically, which can be scary to newbies!
In a nutshell, the idea of hydroponics is to eliminate any obstacles which may prevent the plants roots from reaching nutrients. By being in direct contact with water not only are oxygen levels higher, the plants has constant access to nutrients without spending energy searching.
Hydroponics yield on average 25% more and 20% faster
Different types of Hydroponics:
DWC (Deep Water Culture)
Deep Water Culture is a style of hydroponics that involves submersing your plants roots in nutrient rich, aerated water, as the pump will be constantly running, the roots are constantly exposed to high levels of oxygen, increasing growth by up to 10cm a day!
Ebb & Flow:
Ebb & Flow Systems are also known as Flood & Drain Systems, which is a very simple concept: A timed pump, pumps the nutrient solution into the
grow tray which can contain either separate pots pictured below, or directly filled with growing media, usually with clay pebbles in which the plants will spend their entire life. After a preset time, the pump stops and the nutrient solution drains back via the pump. This is a convenient solution depending on your plants requirements.
This is one of the easiest most cost effective system to build and the reason for its prominence among the hydroponic enthusiasts.
Aeroponics is the unique method of nourishing the roots of the plants using timed bursts of mist, leaving the roots dangling in the air in between sprays.
Who would have thought that naked roots could survive never mind thrive? As it turns out, removing the growing medium sets the plants roots free, exposing them to much more oxygen resulting in faster growth. These types of systems are also extremely environmentally friendly as they use 95% less water than traditional hydroponic systems.
Continuous flow is a catch all term used to describe a whole group of hydroponic systems. The basic idea behind continuous flow is that, as the name suggest, the nutrient solution is constantly being pumped over the plants root system, providing an excellent source of oxygen.
In a continuous flow system, there is a constant supply of aerated nutrient solution being fed to the plants roots. The main advantage of a continuous flow system is the ability to quickly to have the nutrient reservoir in a separate location to the plants, this can have many bonuses on it’s own.
Another thing to note, is that the larger the nutrient reservoir, the easier it is to keep the correct temperature, pH and EC levels therefore a lot of problems that can arise from this can be easily and often remotely corrected.
