I can't go with a viv because not only does my current home not have enough room for it ( though I am moving out in 1 year ), I am the absolute worst when it comes to DIY. I live with my grandmother and she can't help me with DIY either, nobody can. So the RUB is the best option I have. This morning, the temperature was completely normal, after putting the heating on, though the humidity was only at 52% so I sprayed it a couple of times and... hello 80% humidity? So I opened the tub to let some of that excessively humid air out then locked the lid back on and now I cannot get the temperature to rise - I am really annoyed.
