LECA (lightweight expanded clay aggregate) is a great growing medium for plants that allows for excellent aeration and retains water for root health. It is non-toxic and pH neutral which makes great for hydroponic growing (among other horticultural growing methods)! The 1.5oz cup is enough to fill one 3" net cup with some LECA left over
