So yeah, #CoarseSand can be used instead of #Perlite and #Vermiculite (and I would sterilize it before using it).

However, I did read that coarse sand can be too sharp for some root systems? It's something to consider...

"Coarse, sharp, or builder sand, often used in construction, is a primary ingredient in potting media. Like peat moss, sand improves drainage and aeration but does not improve water-holding capacity. Too much sand will make containers too heavy to move. Sand should not be mixed with clay-based soil."

So, like #Perlite takes a lot of energy to produce, while #Vermiculite is mined! Not sure if there are alternatives to either of those out there. Maybe sterilized #CoarseSand? Hmmmm... Something to ponder...
