I keep my few woolies directly under T5 lighting for the heat. I have read that up to 110F is nothing for them. Mine don't stay quite that warm though. I would say anything from 80F and up is good. Mine drop down to room temperature at night, around 78F. I don't do anything for humidity. I used to worry about it, but not anymore. I grow all of mine in a sand/peat mix. I use at least 50% sand. I'll see about taking a picture later.
I wasn't sure if I could mention A.S. or not. Yes they are the source of our plants Swords from the best I can tell.
