another example would be , hempy buckets that have no drainage for example, and the substrate chosen has to be aerated ... use soil and it would become anaerobic and cause root rot , and you would have to ' drain ' it to recover .

horticultural sand is basically washed sharp sand. and 'sharp' just means irregular shape
A little sand trivia, I used to work at a sand pit . Sharp sand is just that , if you look at it with a loop its fractured and sharp . It’s like gold as far as sand goes because that’s what you need for asphalt, it packs and holds structure . All the other sand is rounded by water or wind ,that would be concrete construction or play sand . Any sand can be washed and free of small particles . I’m not sure but I would think that any washed sand would be ok for growing

If you use sharp sand, it protects against larves when its on the top of the soil.
