Know before you buy
Yes, a thorough rinse is recommended before use. This removes any dust or fine particles created during shipping, ensuring your hydroponic system stays clean and preventing potential clogs.
Absolutely. Because they are kiln-fired, the pebbles are durable and can be reused multiple times. Just be sure to thoroughly clean and sterilize them between crops to remove old root matter and prevent disease.
Yes, they are excellent for soil-based systems. You can use them as a drainage layer at the bottom of pots to prevent root rot or mix them into your potting soil to improve aeration and structure.
Hydroton is specifically engineered to resist floating. While some minor movement is normal when first adding water, their density and structure are designed to stay submerged and stable in most hydroponic setups.
The semi-porous nature of the clay allows for a balance of excellent aeration and consistent moisture retention. This creates an ideal environment for roots to breathe while still having access to the water they need to thrive.
