Yes, they are highly durable and can be reused multiple times if properly cleaned and sterilized between uses.
Yes, clay pebbles are an inert medium and provide no nutrition to the plant, so you must add a hydroponic nutrient solution.
These pebbles are generally pH-neutral, but it is always recommended to check your reservoir pH regularly after adding them.
Yes, mixing them with potting soil improves aeration and drainage for plants that prefer drier root zones.
These clay pebbles are designed to be dense and will sink in water, making them perfect for submerged or flood-tray systems.
Continue rinsing the pebbles until the water runs clear to prevent sediment from clogging your irrigation pumps.
Reduce light exposure to the pebbles or use a light-blocking cover to stop photosynthesis of algae spores.
To prepare the pebbles for use, place them in a colander and rinse under cool water until the runoff is clear. For new hydroponic setups, it is recommended to soak the pebbles in pH-adjusted water for 24 hours to ensure they do not pull salts from your initial nutrient mix.
After a harvest, remove old root matter from the pebbles. You can sanitize them by soaking in a mild hydrogen peroxide solution or boiling water, then let them dry completely before storage or reuse.
