Superb Hydroponic Media
L.E.C.A. makes a superb medium for hydroponics gardening because of its light weight, porosity, and inert nature.
You've probably seen clay balls many times and just didn't know what it was. It's used
often in commercial decoration because it is clean and efficient. You may have
seen it in a potted plant at the doctor's office:
L.E.C.A. (Lightweight Expanded Clay
Aggregate) is made by heating clay under very high heat until it puffs
up, like popcorn. This results in a very coarse medium; the balls are about 1/4"
across. They have superb drainage and are sometimes added to denser media to
help promote drainage in the planter.
