Expectations concerning RH inside tent when it's raining and outside RH is 100%.

Anybody have any thoughts? Usually I run a tent at 45% RH. With the rain tonight it's up to 60% inside the tent. On one hand since I'm at week 6 of flower I'm a little concerned. At the same time however I'm probably at a worst case scenario right now with tonights rain. That being said an RH of 60% in a tent on a rainy night is pretty good wouldn't you think?

I'm in the same spot as you. My hygrometer said I had 86% RH in my tent the other day (week 5-6 flower), I put a crappy old ass dehumidifier in there yesterday and it topped out at 70%. This high RH is supposed to get the fuck outta here in the next day or two. I can't afford a $250 dehumidifier to get it even lower. Hopefully after this harvest I will be OK. The RH forecast is saying 50% next week, so as long as that is the truth I'm not worried. We gotta weather the storm. I would love to have 60% at night right now. It's like a fucking rainforest around here right now.
 
Are you worried about mildew? Assuming you aren't fighting it right now, I'd say everything will be totally fine. Same things happen to me, no huge deal. Watch for that pm on the shadier spots of the plants....

Id say it is pretty damn good, cause that means 60 is about the highest your humidity will ever get.

Make sure to keep the air moving around in the tent as much as possible and temp swings to a minimum. They'd be in 100% RH if they were outdoors! They can handle it.
