Hello! I have this pretty purple orchid plant … have it for maybe almost a year and just had to repot it because it was small and root was growing out and even at top of it Bought Black gold orchid potting mix , MG perlite ( was trying to find black gold but unfortunately there were none only MG perlite ) and black gold organic all purpose potting soil. And I hope it grows very well the roots were pretty healthy! Maybe one or two have white roots but mostly bright green
