Yes, the porosity in LECA is where mineral solids collect, ultimately requiring replacement, albeit far less frequently than organic components, but there is a significant “up side” to that porosity. A pot full of LECA, even when apparently dry, holds quite a bit of water that acts to keep the air in the interstitial voids quite humid, and that can go a long way to maintaining the health of plants that are otherwise neglected.
