oh probably around 80%. there is very poor ventilation.
This was a last minute "fix" to a problem and seems to have done it's job.
The humidity has dropped however the moss keeps growing.

Pretty, yes, what I like to see, no.

The RH has dropped in the last while and seems to be more stable now.

The growth is great for the CFL's that I have in there. They are kicking the snot out of the T5's.
