Searching for Mr. Good LECA in France

[rbarata]

My approach to LECA is: I only care about the size, that must be adequate for the pot size (the medium should have air pockets) and type of plant (if it needs more or less water).
Apart from that, I really don't care about brands or whatever. To me LECA is LECA.

As a side note, there's some types that are red. I think they are rich in Iron which is good for rupiculous.
