Hydroponics, also referred to as aquaponics, is a soilless method of cultivating plants or agriculture. It differs from the traditional method of soil farming known as geoponics. The word “hydroponics” comes from two Greek words meaning “water” and “toil,” and means “growing plants in water.”
Plants grow through a process called photosynthesis in which they use sunlight and the chlorophyll present in their leaves to convert water and the air’s carbon dioxide into oxygen and glucose. The chemical equation for photosynthesis is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
Because of the way photosynthesis works, soil is not essential in order for a plant to grow. As a result, hydroponics has become known as an efficient and alternative method to conventional farming.
In hydroponics, the seeds or clones are placed into a medium which allows them to root. The roots are then exposed to a nutrient solution. This makes the plant grow effectively by directly utilizing the nutrients from water via the roots.
Hydroponics is a great way to grow cannabis. Benefits of using hydroponics include the following:
- Higher yields than soil-based cultivation
- Cultivation in areas where there is no soil support
- Elimination of the need for artificial pesticides, assuming that most of the pests live in the soil
