Pretty much all wrong. I would read through the "stickies" on this forum, lots of good info from well educated, experienced people. You definitely don't want temps falling below 75, a respiratory infection is almost a guarantee. Your snake needs heat, and pretty soon. There's no way the snake shed twice in a week. What type of "mulch"? It needs to be spot cleaned whenever the snakes poops, or pees. And cleaned thoroughly monthly.
