Expanded clay is a porous lightweight material that is an excellent amendment to soil or used as hydroponic grow medi. 
We also are the sole suppliers of THE ONLY LECA MADE HERE IN THE UNITED STATES! 
Incorporating LECA, or lightweight expanded clay aggregate, into your potting mix can enhance your plant's growth and overall health in several ways:
Enhanced Drainage and Aeration: LECA's porous structure promotes exceptional drainage, allowing excess water to escape freely and preventing waterlogging. This optimal moisture balance prevents root rot, a common issue with overwatered plants. Additionally, the air pockets between LECA pebbles provide ample oxygen to the roots, facilitating nutrient uptake and promoting strong root development.
Reduced Pest and Disease Risk: LECA's inorganic nature makes it less attractive to pests and diseases that thrive in moist, organic soil environments. By minimizing the presence of these harmful organisms, you can keep your plants healthier and reduce the need for chemical treatments.
Easier Water Level Monitoring: LECA's ability to absorb and retain water while allowing you to easily monitor water levels in the pot is a significant advantage. This transparency in moisture levels helps prevent both overwatering and underwatering, ensuring that your plants receive the optimal amount of water for their specific needs.
Promotes Strong Root Growth: The air pockets between LECA pebbles encourage roots to grow outward and downward, stimulating the development of a more extensive and robust root system. This improved root structure enhances nutrient uptake, anchoring the plant more securely in the pot, and contributing to overall plant health.
Reusability and Sustainability: Unlike organic potting mixes that degrade over time, LECA is reusable and can be cleaned and sterilized for continued use. This reduces waste and promotes sustainability in your plant-growing practices.
