Definition - What does Hydroponics mean?

Hydroponics is a method of soilless growing that is commonly used for growing cannabis plants indoors. In a hydroponics system, there is no soil involved. Instead, plant roots are constantly bathed in a mineral-rich nutrient solution, where they either hang loosely or are anchored in a soilless grow medium such as rockwool, clay pebbles, coco coir, or gravel.

MaximumYield explains Hydroponics

In addition to being a favored method of growing marijuana, hydroponics is suitable for commercial food producers and hobbyist gardeners alike. Hydroponics possesses several advantages over a soil medium. Unlike plants grown in soil, plants grown in a hydroponics system do not need to develop extensive root structures to search for nutrients. It is easier to test and adjust pH levels.

In the hydroponics method, plants are raised in an inert and perfectly pH balanced growing medium where the plants only need to expend minimal energy to acquire nutrients from the roots. The energy saved by the roots is better spent on fruit and flower production.

When it comes to growing indoors, hydroponics is preferred because it is considered cleaner than soil, and plants can be grown a lot faster.

There are several types of hydroponic systems cannabis growers can choose from, including:

  • Nutrient film technique (NFT)
  • Wick system
  • Ebb and flow (flood and drain)
  • Water culture
  • Drip system
  • Aeroponics
  • Aquaponics
