I was all out of tin foil and kept forgetting to get some to put on the top of the screen so I was just laying a hand towel on it to cover about 60% of the top. I was having to mist 3 times a day to keep the humidity up because its gotten cold here and the air is dry. A random thought came to me and I thought to mist the towel, so I tried it at night. I forgot to check on it in the morning so after work I went and checked on it and it was still at 51% humidity. It normally drops to 43% during the day. Anyone else ever tried this?
