Hydrogarden PLANT!T 10L Clay Pebbles Bag

Product Information

More importantly, clay pebbles are cheaper than most growth media, and as mentioned above, they can be used and reused, making them cost-efficient. Soil is by far the most familiar, and common grow medium for both beginner and professional growers across the globe. Rockwoolmay sound like an 80s rock band but it’s actually melted rock spun into fibers and pressed into cubes. It’s produced by flash-heating up to 2000°F (1200°C), regular, slightly wet clay balls in a super-hot oven. This is why you should be removing the clay pebbles from your hydroponic system every few weeks and giving them a good rinse, washing away any nutrients that may have taken hold.

I am gearing up to use them soon as I believe the warnings are due to potential choking hazards rather than poisonous make up!

If you’re totally sold on using expanded clay as a growing medium but haven’t tried it yet, I suggest starting with easy plants to grow in expanded clay pellets.

LECA was initially developed for use in the construction industry, and the firing process was designed to make a lightweight material that was well-suited for structural use in place of traditional bricks. Ceramsite products often come in a variety of colors and often perform as well as traditionally sourced expanded clay products. Rinsing and soaking befor use can be very time-consuming and the reddish dust can get everywhere in the process.

Growing media serves as the anchors of your plants, providing them with nutrients, water, and oxygen to their roots. Drainage: Traditional indoor plant pots have drainage holes and stand in saucers to allow excess water to drain freely.

When compared with soil, coco tends to dry out a lot quicker, meaning your plants will need to be watered more frequently. If you’re looking for a way to add some greenery to your home without taking up too much space, then you might want to consider growing houseplants in clay pebbles. Hydroculture plants are measured the same way as soil plants, however the grow pots are sized by diameter plus their standardised heights, which allows a water meter to be fitted. They are triple filtered to remove dust and undersize pebbles and they also have a lower bulk density than clay pebbles of other brands, which means they are more porous and have a better ability to retain water.Secondly, I saw you mentioned use in aquaponics systems, however I keep aquariums with invertebrates. You can choose to add a layer of mesh or cheesecloth between the pebbles and soil to keep the soil up where it belongs, but this isn’t necessary. Simply place them into your growing container, either on their own or mixed with another growing medium, before adding your plants in. In short, decide first on the plants you want to grow and then choose which growing medium between clay pebbles vs perlite to use. This not only helps reduce the chance of overwatering but also allows your plant the possibility to receive more nutrition due to the increased amount of irrigations you can now provide it.
