9. Allow the clay pebbles dry.

Allow the clay pebbles dry on a colander placed over the pot. This will allow them to drain. Clay pebbles will completely dry in 24 hours. Clay pebbles is a great growing medium as it retains moisture well. Therefore, clay pebbles will not drain quickly.

Allow the clay pebbles to dry before shaking them. This will speed up their drying time. The remaining moisture will be drained by shaking the clay pebbles.

What to avoid when using reusable clay pebbles

These are some helpful tips for hydroton clay pebbles use in hydroponic gardens to make sure your plants get the best out of this growing medium.

Things you should to when reusing Hydroton clay pebbles

  • Allow clay pebbles to soak for between 6-24 hours before putting them in the hydroponic gardening. Clay pebbles are heavier than clay pebbles, but they will provide more water for your plants because the pebbles retain their moisture.
  • Soaking clay pebbles in water will remove any dirt, dust or debris they may have accumulated during their stay in the box.
  • After soaking the clay pebbles, rinse them well. Rinse the clay pebbles well as you would with cleaning clay pebbles.
  • Add nutrients to the clay beads after rinsing. For exact quantities or proportions, refer to the instructions on the package.
  • To avoid phytotoxicity buildup, remove plants from the hydroponic gardens and rinse. Clay pebbles are by their nature low in nutrients and have neutral pH. They can absorb nutrients from hydroponic gardens, but they may become toxic if they do.
  • Be sure to check for any whitish remains. Use a pH-adjusted fluid to rinse the clay pebbles and plant. This is important as phytotoxicity buildup can cause plants to become starved.

Things you shouldn’t do when reusing Hydroton clay pebbles

  • Clay pebbles should not be used as a soil replacement for outdoor gardens. Clay pebbles can be mixed with soil, but it should not be used as a soil substitute for outdoor gardens.
  • Do not allow clay pebbles dry out. Clay pebbles is very moist, but it can dry out as plants use it for water. When dry, hydronic clay pebbles can be harmful to plants.
  • Clay pebbles should not be reused without being cleaned (soaking, sterilizing, and rinsing).
  • If you don’t know how to use isopropyl alcohol or peroxide, do not clean clay pebbles.
  • If you don’t have a water source, a regular pot is not suitable for hydroponic gardens. Algae growth can be caused by regular pots. This can also cause drainage problems.

Hydroton clay pebbles are a good choice for hydroponics


Aeration and oxygen are two of the most important things a plant needs to thrive.

Clay pebbles has tiny holes that allow air and water to reach the roots of the plants you are growing.

You will not need an air pump to oxygenate your water if you use the Kratky Jar method of hydroponics (the DIY version of hydroponics).

This difference can be made up with LECA pebbles.

This type of hydroponics can be explored by learning how to fill Kratky jars.

Both natural and sterile

Hydroponics can use synthetic materials, such as regular Rockwool.

Some are more natural than others, but they retain too many bacteria like soil and dirt.

Hydrotonic clay is a wonderful environment. It is both natural and can be sterilized easily.

For those who are eco-friendly, clay pebbles can be dumped in the soil where it naturally breaks down.

Simply place it on clay pebbles over the soil, or mix.

Good pH balance

They are also pH balanced and don’t inhibit plant growth.

Hydroponics causes water to lose some acidity.

To grow well, the plant requires some acidity.

For pH, we prefer water between 5.5-7.

Some media are quick to discount it. Clay isn’t.

Good water retention and drainage

Hydroponics is all water (hence, the hydro-) in hydroponics.

Any medium used must be capable of absorbing nutrients and delivering them to the plants.

Clay pebbles are a great medium.

Affordable price

Hydrotone clay may not be the most affordable material, but it is very close.

Ideal for seeds

The initial seed in clay pebbles is not as simple as you might think, but it is possible. It is better to have a pod of seeds or use Rockwool only for seeds.

Final Thoughts

The most popular hydroponic media is hydronic clay pebbles. Because they retain water very well, your plants will always be able to access the water they require to grow and develop.

Hydroponic clay pebbles can be recycled, which is why they are so popular as a growing medium. Clay pebbles is not distinguished. They can be reused for a long time and can be cleaned repeatedly.

Clay pebbles don’t have a shelf life. However, you should throw them out if you are unable to clean salt buildup.

How often you clean clay pebbles will affect their lifespan. It is important to have a cleaning schedule. You should also have another set of clay pebbles for your hydroponic gardening garden to use while you clean the clay pebbles.

Cleaning hydroton clay pebbles to reuse is one of the many tasks that you will need to learn if you have a hydroponic garden. Your plants will thrive in a hydroponic garden that has a steady supply of fresh water and clean hydroton clay pebbles.
