Portable Air Con Advice

Installed my portable air con for my room today...It's awsome no more having to wing it,stressing about Temps n Humidity this summer...
Just the 1 question for anybody in the know with experience,knowledge for them.
Temp goes up/Humidity goes dwn.Yes
Temp goes dwn/Humidity goes up....
What is the best way to control (if possible?) the Humidity when lights go off and I start dropping the temp?
Day temp is 23.5/24.0°
Night temp is between 18.0/19.0°
When I flick it over for sleep time Humidity starts ramping up around the high 57%/62% for sleep time.
Should be worried that it's not in 40%/50% range when flowering? Or am I just being pedantic over it and should not worry about this?...
Quality of the final product is everything to me and this only being my 2nd grow...Would be keen to hear what the more experienced growers think?
Thank you

Wouldnt hurt to add a dehumidifier. The lower the flowering RH the better. I like to keep RH under 50% for the entire grow. Under 40% in late flower.

Yeah. All in one swiss army type appliances never work as well as you want them to. Run an ac. Run a dehumidifier. Run fans. Etc. Etc. Etc.

People may call me crazy but i like to keep 20-40% throughout the entire grow. Low humidity isnt really something to worry about to much. High humidity=mold. No one wants that.

Wicked sounds interesting...
You seem to really know your stuff...
Me,I've smoked it since 16 love it its ah reasonably big part off my every day life but in saying that it dosen't control it...I've included ah pic of my set up,
First grow was in ah tent but knew I could do better so set about doing better...
My room is 5ftx5ftx6ftH,am running 2x electric sky V2 leds with ah 3rd turning up next week an over kill on light but really want to get ah c02 set up running by early next year.
Question....While running my A.C. and no c02 at the moment do I still run my exaust and inlet fans as per usual?
Just have read while using C02 they all go off with only A.C running,but can't find anything on using A.C just for ah normal grow?
Ya thoughts would be appreciated...

You should have a constant supply of fresh air. Put the ac outside the grow area, wherever the intake are is coming from.

You growing in like a shed? Looks like your setup to run a sealed room with co2. Either you need fresh air or co2.

Yes thats the plan next year but for now plan to run exaust,inlet n thermostat heater at night and air during the day to cool it,when I built i put 60mm thick polystyrene in the walls and roof to regulate and hold the heat.Can control temp at night to within .1 of ah degree just during the day is ah bit of ah problem summer starts in 2days and startn to heat up especially in ah shed,inlets pumps in warm air n just up to speed on the ways of A.C.

Yea when I run lights on at night Temp/Humidity are allgood 23.8° Humidity at 45/48% but as soon as it heats up just all turns to shit so to speak Temps allright between 18/19° but Humidity gets up 60% so will run air con/humidifier in sync tommorow with both fans and see how i go
