Surprisingly our nurserys /landscape centers out here called star nursery don’t carry lava rock at all, not even in the bulk for decorative rock. Don’t understand why cuz with az legalizing I’m sure I’m not the only one that’s looked for it. I have to get it at Lowe’s or home Depot in vigoro brand for 5 bucks per .5 cu ft bag which gets pricey, about the same shelf price as perlite by volume
