what up again? i watched this hydroponic tape i got from the library and they had what looked like aquarium gravel. then it me, is it possible to use perlite as a sole medium in a hydroponic grow? why and why not? and how would a mix of perlite african violet and sand in a fill n drain getting fed twice a day do? expert and all advice is welcomed, let me know.
