I would go to your local lumber yard,I got 75# of pure white coarse industrial sand for less then $5. Ask what type of sand they have and go from there. I had great difficulty finding white sand....even driving 60 miles to go to lowes and to no avail,until I went to the local lumberyard and they had it! It`s very nice sand, I think I will never go back to that nasty perlite for non Nepenthes again!(although I might use bark instead of perlite for my Neps too once my current perlite supply runs out)
