Do you have cats?

LOL! Couldn't resist! I have no idea myself.

Lol ya but it really was a nasty when I got a good wiff of the contaner so gross dude about made me pass out. The live stuff that I have doesnt stink just what I used in a sealed contaner that I left in the sun alil to long lol.

This is pretty much what a bog or swamp smells like. Normal.

I've gotten this kinda smell from my pots if I keep them too wet -- if they soak in water without ever letting the saucer dry out. I've also noticed the roots tend to react very poorly to this very quickly, getting translucent and bloated. Not sure if they get over it eventually, when it happens to me I swap out the media and let the plants dry out more often.

Ya I seemed to notice the smell go away after you let it dry abit the plant seems to like semi soaked moss. My live moss is thriving.
