Not sure what that is? But I don't think it is the same type of humidifcation we are talking about.
I do know some smokers use a certain type of cat litter & train it to hold the right RH. A lot cheaper.
I use the expensive kind because I'm both Lazy & unsure!
If you want the info on Kitty Litter I can look for it tomorrow.
Let me know!
