I'm also talking by experience. I've grown many strains under the conditions I described, in a dank, moldy and wet part of the world. Mold does not "start" around 50, that's bunk. The RH has to be higher than that to create optimum mold conditions. I'm also not concerned with what people say on other forums, they tend to be full of unfiltered poor information, just look at what they say about autos. I do try to lower my rh during flower, I lower it from 70-60 to 60-50. 55 is just right for me.
