the last few days our area has had a lot of humidity in our area. I cant keep my humdity level under 70%. sometimes it drops around 67 or 68 but it never goes above 75%. its not damp enough that the substrate feals damp to the touch and there is no misting on the glass walls. should i be worried about IR or other problems? they say that higher Humitidy can cause problems, but how high is too high. i have tried to find out buy searching online, but all i can ever find is that it says high humidity levels are dangerous but how high is too high and what is border line. thanks i just need some numbers to look at.
