Clay Balls for Hydrotons, Leca Lightweight Expanded Aggregate, Ball for Hydroponics and Aquaponics 1 Kg : Approx. 3-4 Litre Easy Growing Medium

These are great. Floats on water and my monstera nodes are finally developing roots in these fly ash balls(After having failed three times in plain water).P.S: I don't think this is leca, since leca is supposed to be made of clay and it expands in water and unfortunately I couldn't find a single seller selling leca here. All that you see mostly is fly ash or concrete rolled in a layer of clay.

They serve the purpose bit delivery too too mich time and the price is also at higher end

Good quality 👍👍

Most of the balls are very small which will just drop through net pot

Not as expected:(
