I had fine dolomite like sand, I know.
I also do not like perlite around the plants, I don't really like how it looks, but it is cheap and ultra light weight, which means shipping is cheap for a lot of it.
There is the question weather adding liquid fertilizer would make perlite be filled with minerals, instead of being "neutral".
Pumince is nicer, however as far I have have seen, it is much more expensive and the sellers seem for some reason to only sell it wet, which becomes heavy for transportation. I cannot find it anywhere at the big commercial plant places anyway.
I wonder about the Thiamine HCL, seems to be used for plants by some people and the active ingredient in some products, not sure about it. Well, not really for mineral soil amendment.
