Peat Moss??

Howdy all,
I was just wondering if peat moss is something that could be an appropriate substrate for BPs. I use peat for my inverts and was thinking that solid-packed peat moss might be a cheap way to go for BPs. Let me know what Y'all think Thanks!

I have no experience using peat moss, but I am wondering if it would tend to hold too much humidity and possibly urine, causing alot of bacterial growth. I really don't know. :confused:
