I am really having a lot of troubles keeping Salinas humidity up and she is in a shed right now. I went and bought a 24x16x6 Rubbermain tub with a locking lid. I have a 11"x12" piece of flexwatt I got from Matt (very good person to do business with of course). I know this isn't huge for a BP enclosure, but Salina is still a small snake. I have a Rheostat thermostat(I know its not the best but its all I have for now), and a digital thermometer/humidity guage.

Here goes my questions.
1. Is that piece of flexwatt big enough (ambient temp in the house is always at least 75 degrees)?
2. How many holes should I make with the solder gun?
3. Can I tape the flexwatt under the rubbermaid and place it on wood without it being a fire hazrd?
4. With the flexwatt taped to the Rubbermaid, can I use paper for substrate right now?
5. Am I missing anything?
