Led basement grow tent help (Heat issues)

Hello RIU. Fishing4life here and Im back for some more general help on mu heat issue. At the beginnig of my grow i had this where it was to low and humidity aswell. Welll Im back with the opposite question.
What is the best way to lower the heat temps in my small 2x4x5 grow tent. Im lacking room now tho.
I recently flipped from 18/6 light schedule to a 12/12 schedule. I installed a dehumidifier to ballance out my humidity wich was causing lots of heat so i made a custum pc to go around the out port of the dehumidifier and up and out my tent. Thats helped significantly but im still at 28°c ish, 2° higher then what i had it set at in veg. I also put in another 6inch passive intake and a 4 inch aswell with fans blowing from outside into the passive intake.
So far my humidity loeveks are great, 47%plus or minus since inhave a controller set and dehumidifier going all the time. (Does not alow to be shut on and off from controller, as you have to puch the power on button for it to come on once power is turned off to dehumidifier).
I cant rely on the basement room temps and hums as they realy fluctuate as the weathrr gets warmer and cooler with outside temps. Its a basement and the concrete generaly gives off moiture in high temp times.
Im stumped on what else i can do without an a/c. Should i remove intakes? Should i remove or add something else, maybe an ice box thats pulled in from intake fan?
I think i covered everything that ive done or tried and I need help. I DONT WANNA LOSE WHAT IVE ACCOMPLISHED SO FAR IN MANIFOLDING MY PLANTS. Any info/sugestions would be greatly appreciated.
Thanks in advanve. F4L
(P.S. , I deleted my pics but my grow journal has them showing what ive done and what it lools like as of yeaterday)

Repost your pics here so I can take a look. I've got a few ideas, but I need to see what you're working with.

I will post updated pics of what ive got going on once im home. I started out with just one 6inch passive intake, 1 exhaust thru a carbon filter, 1 humidufier and one heater for my veg. Now its snowballed into what ive got now to keep my hum down and try to get the temps down. Will post soon. Thanks for the reply

Sounds good. I wasn't trying to be lazy, or anything, it'll just help others following along, if the post ends up being many pages.

That's not a bad temp for LEDs as long as you can bump your humidity up a bit.

Are your plants suffering or are you just worried about it?

No problem JSB99. Sounds good to me.
3rd Monkey, as of this moment my hum is at 49% and hovering and my temps are at 21°C. Im worried about the temps and humidity being higher then i started with since this sgiuld be that time (in my tent obviously) that here in southern ontario we would be getting cooler and less humid nights, not constant heat and humidity.

So heres the run down of my tent. The right side if my tent has a 6inch passive intake thats been there since day one. The led lights are 24 inches or so above the plants as directed. I have an exhaust fan in the top left corner of my tent with a charcol filter opposite my intake. An oscilating fan in bottom left side of tent, opposite my intake and a hot mist humidifier by my intake innthe back right corner. ALL that has been there since day one and uo till now.
Once i flipped I noticed these hot and humid changes. So ive added a degumidifier with a custom exhaust out the top of my tent and shuffled some inner parts to accomodate that. Then i added a 2nd 6inch passive intake on the left side if my tent and a 3d passive intake at the top left side of my tent wich is 4inch. These releave the dehumidifier from struggling with the exhaust, and ive lowered the controller for that awsell. Ive got that set mid range and the exhaust runs 24/7.
Now that im home and the lights have turned on, the tent humidity is 47% and the temp is at 29°C .

Looks fine. I wouldn't change anything. Here's a VPD chart to assist you.

Awesome. Thanks for that chart. Much appreciated. Was just worried about the temp being higher now that ibe started to flower then when i was in veg. All keep a good hold of it then. Thank you

So since lastnight, its spiked up to 30.4°C with the lights on for 8hrs. According to that chart, with 47% humidity, this is bad, in the red zone. Even the previous resdings lastnight were bad. Temps are great at 21 when lights OFF but still, with 47% im in the yellow zone.
Im realy trying my best to get thia right and make the ideal envirinment for tge ladies.
***My goal is 23°C with lights ON and 47 % humidity, which i got from various sites and went mid way between certain numbers, yet thats in the red zone aswell. Damn it.
Everywhere ive looked, its told me that high temps and humidity ober 50% is bad and can lead to bud rot. I dont want any of this.
**My probes for the humidity controller and my temp controller are hanging above my plants, under the led lights a d getting blown on by the fan every so often and by the dehumidifier. Im bot to sure i could put it anywhere else in the tent as this would gibe me different readings then what the plants are experiencing at the moment and because of various equipment that would make the probes read something but in reality its being hindered by that equipment.

I do use the led w/h lower heat and also save energy, that reduce some trouble during the growing, but your temp not bad there, yes need to take a more look at the humidity. Temp 75°-85°F and 50% - 70% humidity that most of us manage. Happy growing buddy !

That dehumidifier is big enough to add a lot of heat to your tent... ANd big enough to actually run a whole room... You should think about setting it up outside, that's ridiculous!

you're probably pushing too much light for them small of a plant. depending on wattage you could possibly just use one light .
i often see 28/30c°C in my room with a 50% humidity and plants dont mind it 35°C id start to worry

if your environment isn't 100% perfect i wouldn't sweat it. you can still grow some good plants

Yeah, how many watts are you pushing through the lights?

158 Watts real power it says. Ive had 2 lights and havent had a problem till flipp. I know my basement/weather has to do with the hunidity, which is why i can rely on solly relying on the room environment as it fluctuates.
I realise that the dehumidifier does the job for a room and but its doing its job and keeping it constant with with himidifier which i have on a controller set for 47%. ,But the bad side its throwing heat and ive got it exhausting out the top of my tent. Theres gotta be a way to grow in a basement and not have to jam pack all the equipment inside a small 2Wx4Lx5H tent. I get the plants are called weeds for a reason and pretty hardy but its taken me 2 months to make my manifold and I dont wanna risk even remotely loosing them, so making it kind of ideal for them makes sense for me and on a plus side, wouldnt have to worry about anything happening to them.
Ive made this far and I plan to finish

I'd say you're good on the lights, and your plants look pretty healthy tbh. I wouldn't worry that much unless your heat started increasing a lot more (over 30c).

I also used to run a tiny dehumidifier inside my tent, but i ended up taking it outside because the added heat was wrecking my plants...

And yeah, finally, tent's do get hotter as they get filled out... More respiration, more leaves to block airflow, more humidity, etc.

Looks to me like these lights worked fine.
So on average during lights on my temp is 30°C and hum 47% and with lights off about 21 °C and 47% hum.
To high of temps for flower during the day?
Only been 6 days, maybe slight defoliation and may have to resort in dehumidifying my room so lower the temps, may raise humidity tho.

Plants will be fine upto 35c. your fine. Just keep your humidity at the right levels. Look at VPD chart.
