What is Hydroponic Farming?

Hydroponic farming refers to a technique of growing plants without using soil as the growth medium. Plants are grown directly in nutrient-rich water, which is carefully monitored for optimal nutrient levels, pH, and other factors. This technique promotes faster growth and higher yields because plants have direct access to nutrients and oxygen.

The method utilizes various systems like ebb and flow, drip system, wicking systems, aeroponic systems, and more to promote growth. The ebb and flow system uses a water pump to periodically flood the tray with nutrient-rich water before draining it out again. The drip system uses small pipes that drip water onto the root base for sustained nutrition delivery while aeroponics grow plants by misting sprayers.

Vertical gardening is another way of indoor planting that has become very popular recently. This method maximizes space utilization by growing crops vertically on stacked layers. It requires careful planning of lighting and nutritional requirements of different crops.

Capillary action also plays an important role in hydroponic farming where plants uptake nutrients through capillary tubes, a kind of passive transport mechanism.

Using an air pump to provide appropriate carbon dioxide levels further boosts biomass growth. Aeroponics works by spraying the roots of plants with nutrient-dense solution providing sufficient oxygen through air supply pumps.
