Yep, up until 2 days ago my dehumidifier was running non-stop to keep RH at 55%, now it's in the mid 40's. My room is dropping to 67' at night but 77-80 during lights on. Pretty decent temps and I'll take the low hunidity, saves me on some juice. My plants don't seem to mind it so far.

I wouldn't raise humidity...unless you need it for clones or something?
Well if you are vegging a higher humidity is good. I try to stay around 70%.. Flowering though it's best to stay at or below 50% to avoid mold (bud rot). There's nothing worse that finding a big patch of brown goo on your biggest cola...been there done that. Never again as long as I own a dehumidifier!!

I like around 40% when flowering. Less chance of mold(PM) and more trics from the dry enviroment. Alot of guys drop to 30% the last two weeks of flowering.

Yeah I'll drop down lower too once the buds start getting thick enough to not get any airflow through them. That's when I start to worry, the last few weeks. I've never had any PM problems. I thought that was more temperature related than humidity. Or a combination of humidity and cold temps. I know PM like cold..
