Hydroponic Cannabis Cultivation: How to Do It?
There are many hydroponic systems, and to understand the differences, one must navigate through a vast amount of information. All these systems have their advantages and disadvantages. Their choice primarily depends on personal preferences and growing goals. In this article, we will present five of the most popular hydroponic systems designed for cannabis cultivation.
Hydroponic Growing System
Hydroponics is a method of growing cannabis where water is used as the primary medium. Hydroponic cannabis refers to any cannabis grown without using soil. Hydroponic cannabis can be grown in various ways, such as in clay pebbles, solely in air, or in rock wool.
Advantages of Hydroponic Growing
In hydroponic cannabis cultivation, plants can grow taller, grow faster, and achieve higher yields. This is primarily because nutrients in the hydroponic system are much more easily accessible to plants. Nutrients are dissolved in water and penetrate directly into the root system, as there is no soil present. In contrast, in soil, roots must search for nutrients. Easy access to nutrients allows plants to save energy, which they can then devote to growth.
Disadvantages of Hydroponic Growing
This system can be somewhat complex because it requires many interventions from the grower. It is necessary to monitor the pH level so that plants can absorb all nutrients and grow as much as possible.
What Growing Media Are Used in Hydroponic Cultivation?
Growing media are soil substitutes used in hydroponic cultivation. The hydroponic cannabis growing system requires a growing medium that allows the plant to receive enough air while the plant's roots reach the nutrients contained in the water. In hydroponic cannabis cultivation, you can choose from many growing media. Below are the most popular ones.
Rockwool Stone Wool
Probably one of the most popular hydroponic growing options. Rockwool is a material made from melted stone fibers. The main advantage of this wool is its ability to retain water, ensuring sufficient hydration of the root system. The disadvantage is that it may contain a high pH level.
Air
Plant roots are primarily designed for soil cultivation, but they can also grow in air. Air can be a very effective growing medium because roots need plenty of oxygen to grow. However, it is necessary to maintain constant moisture to prevent root drying.
