Clay pebbles are becoming of the most popular growing medium in hydroponics. They are made of clay subjected to very high temperatures in a rotating kiln. This cause clay to expand, resulting in a highly porous medium that has excellent air and moisture retention. Clay pellets are the best alternative among other organic substrates. Most growers use clay pellets as a base layer in combination with other grow mediums. Why has clay pellets gained so much popularity among the hydroponic growers? Obviously, this growing medium is popular because of the several benefits it offers to the hydroponic gardeners.

Benefits of using clay pellets as growing medium

Clay pellets can be used in all types of hydroponic systems and offer many benefits, including;

#1. Durable 

This is one of the main advantages offered by clay pellets. This growing medium can last for several years and can be used again and again. Unlike some of the growing media, clay pellets do not break down easily. After each growing season, clay pellets are sterilized with isopropyl alcohol then rinsed with pH balanced water. This will save growers a lot of time and money that could have been used to look for another growing medium before the onset of the new growing season.

#2. Excellent moisture retention 

Clay pellets are porous materials, which absorb and retain impressive amounts of moisture. Therefore, hydroponic systems that use clay pellets as growing medium don’t require frequent watering.

#3. Better aeration 

The clay pellets are porous and irregular in size and shape. This increases the aeration in the roots system of the hydroponic plants. Better aeration means superior oxygenation which is vital for the health of the plants. Better supply of oxygen to roots allows optimum absorption of nutrients, which is essential for high yields in hydroponic plants.

#4. Good drainage 

This growing medium offers the best drainage that crucial for maintaining the health of the root systems. In this case, the likelihood of water-logging is reduced. Therefore, the cases of root rot are eliminated when clay pellets are used as a growing medium for hydroponics.

#5. Easy to stabilize pH 

The level of pH plays a crucial role in every hydroponic system. The ideal range of pH should lie in the range of 5.6 to 6.3, and serious problems may occur if the pH falls out of this range. Fortunately, it is much easier to stabilize the pH in clay pellets as compared to other growing mediums. This is so because this growing medium has neutral pH. The growers prefer using clay pellets because they make the job of checking and adjusting the pH much easier.

#6. Affordable 

If you are working on a small budget and want to spend less on growing medium, then clay pellets are the answer. Clay pellets are relatively cheaper to make as compared to most growing mediums. Moreover, clay pellets are readily available in most hydroponic or home improvement stores. Therefore, you will definitely save a lot of money on this growing medium.
