Dehumidifying an auto tent?!?!?!?!!

Alright so I'm new to this whole thing I'm currently into the 4th week of flower on a gorgeous blueberry x amnesia haze auto and as each week has passed in the flowering stage I have noticed a slight jump in rh in my tent. In the mornings I have seen it spike up to 65% rh but I'm aware of the fact they tend to give off more water vapor in the early light hrs after their dark time. I know I don't have it as bad as some people I have seen on here talking of upward if 70 an 80 rh but like I said before I'm going into week 4 of flower an I have notice a decent jump from week to week in this phase. With that being said they normally come back down to around 45 or 50 % but it would be a shame to lose my plant to mold or something after all the work an money I've put into this thing. I purchased a vivosun mini dehumidifier that's supposedly rated to dehumidify up to 250 sq ft which is more then enough for the closet my tents in ( it's only a 27x27x62 tent) my main issue I guess would be where should I put the vivosun at? In the closet outside the tent or inside the tent? But if inside the tent would my exhaust fan setup negate the dehumidifier seeing as how it's rated to move 200 cfm when perfectly set up ..man there soooo much to consider..lol it ain't as easy as throw it in the dirt an give it some water lol.anyways I'm brand new to this an it's becoming abit over whelming so any help would be appreciated. Here a pic below of the haze!

How long are the lights out for? Do you live in a variable climate? My house can swing 30-40% humidity from summer winter and 10-20% in a few days if wind directions are favours

65% isn’t bad for the stage you’re at. Only when you have buds forming do you want it in the 45-55% range. Nothing to mold up just yet haha

I live in a moderate climate.. the winters are cool but normally not crazy bad. An the summers can get hot but it's normally humid here alot let's just say I'm in the appalachian mountain chain of lower states. So winters are wet an cool an summers can be hot an muggy. The pics are from about two weeks ago. She is forming buds now thus the reason I'm starting to get abit rattled by the rh. I have four to six weeks tops before it's time to cut her down. I just don't want mold to trash my plant. Do you think maybe if I cut my fan down to the lowest speed possible (since I got a control knob) maybe it won't replace the air as quickly an it would give the dehumidifier time to work. Cause I don't think if I just sit it in the closet outside the tent it will do much an the reason being is because the closet door stays open enough to run the exhaust duck through it an out into the next room.

If your only running autos, consider running lights 24/0. This is what I do now, helps keep temperature and rh steady. My tent is in a basement however so the outside temp and RH stays fairly constant throughout the year, so I just run an inline fan (outside the tent) to pull the moisture out that the plants create. Once dialed in its basically set and forget. I get a steady rh of 55-60%. Only time I've had bud rot/mold since was when power went out and the rh spiked for a night. You might need to consider some automation/controls of the fan and dehumidifier if you have large temp and rh swings to deal with. Otherwise just try and manage the environment outside of the tent to help with that as much as you can.

Well my rh is steady between 50 an 55 but it's steadily risen to that number over these past few weeks of flowering. I've ran her on a 18/6 schedule. I'm thinking seriously about getting the ac infinity fan I believe it's automatic. So I mean in flower as long as I'm below 60 hopefully I'm alright. But in the mornings soon as my light comes on I have noticed a spike in humidity up towards 65. But so far it comes back down to between 50 an 55. Currently at 53.. lol I will say. Being brand new to this this can be abit worrisome

Send that mini dehumidifier back if you can. The AC & TerraBloom BOTH have controller options.
You're better off getting a bigger dehumidifier that can lower the RH outside the tent.
You might want to cut back on the fluid too.
Even without any controller you can place the dehumidifier near your intake and cut that back.
I'm more hands on, don't like or care for automatic stuff but that's just me.
Vivosun stuff doesn't usually last very long...

Well I will say this about that lil guy my tents in a walk in closet that's probably 5 x 5 but the tent itself is only a 2 x 2 but I've noticed since I've had it outside the tent it hasn't spiked to 65 again it's been as low as 51 an seems to ride along the 55 range. But after looking into that ac fan I went ahead an grabbed it. I like the idea of not having to worry sooo much about the climate an humidity in there. Of course I'ma still keep an eye on it. But less worry for me is awesome. And I've been a little more generous with the h2o then I normally am. She was showing nitrogen burn on the tips of several leaves so I did have to give her a light flush. So far so good.
