Raw Material: Our expanded clay pebbles are made from 100% natural clay and fired at high temperatures, which means they have a strong structure and no pungent odor, not easily broken and reusable. Besides, the soil is rich in organic matter.
Breathable Structure: There are small pores on the surface and interior of the expanded clay pebbles, which can not only inhale and store water, air and nutrients, but also provide good air permeability for the roots of plants, so that the plants can grow healthily.
Use Instructions: Wash the expanded clay pebbles before they are introduced into the hydroponic system. Our expanded clay pebbles can soak the water when you are watering your plants and release it when the roots need water.
