I avoid this type of enclosure for just such reasons, but it might help to run it with heat (while un-occupied) for a week or more to air it out. You'd not want the heat over 90* for a BP, & even then only the warmest "basking" area. I think you might be smelling the RHP also? I think someone else mentioned this issue & those using the same products said they had to run the RHP on full-blast for a few days to cook off the fumes from it? I hope you have a garage you can do this in, so you don't have to smell it either.
