I pulled that referance from a book I have. Let me see if I can find something on it online.
The egg crate is a nice idea. I can't control temp though on breeders. It's whatever TX weather gives me. I keep them outside during the growing season.
Sterility is listed as a harmful side effect of brown blood, however my question is, is this necassarily a harmfull thing? If I can limit the effects to just that, than I would say no. But I am not so arrogant to think I can control something like that with such preciseness. Since it's winter, I do have the option of attempting something like this. But question whether or not it's a good idea.
