Help, Too HOT in here! need to upgrade indoor vent

Hello, i always had a problem with the temp, however in winter it was ok, i mean it was controlled after a lot of efforts, but now the spring/summer as arrived and im having too hot temps.

So im searching a way to get those temps lower, i have a plan but i dont know if it could make any difference, so i need your advises please!

Indoor details:
Wood closet
40cm X 60cm X 2.10cm (in inches: Wide;23, Depth; 15, Height; 82)
It have two "rooms" veg and flower, veg is bottom and flower on the top, veg is about 37 inches tall and flower about 43 inches tall.
Lights: Veg room: 7 x 42 Watts Cfl - around 2800 lummens each. Flower Room: 1 x HPS 250 Watts.
Ventilation:
-One "Centrifugal Fan (vortex) 230 m3/h placed in the top left corner in the flower room attached to carbon filter.
-One fan 180 m3/h which blow airs inside the indoor placed bottom left in the veg room.
-One Clip Fan moving the air in the veg room.
-One inline fan blowing directly in front of the hps bulb.
-some holes and 2 mini computers fan in the table which divide the 2 rooms for letting the air go up (they are covered for total darkness in the flower room)

Veg room never has temp problems, winter or summer works smooth.
Flower room more complicated, winter 25-31 C° (77-87 Farenheit) but in summer go a lot higher 29 - 38 C° (84 - 100 Farenhiet).

So i believe that the space is too small then the heat "stuck" there even thoug the extractor has a lot more capacity than the volume in my ENTIRE room (veg-flo). so maybe to help this i was thinking putting 2 big fans 100m3/h at each side in the middle table which separate the 2 rooms in order to take out the air from bottom veg room (which is colder than the air in the top room) and blowing in this air to the flower room.

HELP please!!!
Thank you!

I would consider insulating between the layers, I assume the veg room heat is contributing to the flower temps. The veg air may be cooler, but the lights are heating the floor I bet. Maybe a small fan in the veg wall sucking air out and pushing it through ducting into the flower wall so air moves across the canopies? 100 degrees is brutal, I would be putting frozen water bottles in there or something lol

Very difficult to diagnose as your descriptions are confusing, pics would help. It doesn't look or sound like you have good incoming air (forced air, like putting a hole in the lower section and attaching an inline fan to suck cooler air into the cabinet). The most effective way to reduce heat is to pull in colder air, second to that is to suck it out through the exhaust. If both of those are covered you'll need to consider an air conditioner or cooler lights, like LED's.

Is something like that:
left bottom = air intake (from outside) fan 180 m3/h
left top = centrifugal fan exhaust 230 m3/h
right bottom = cfl lights deck
right top = hps bulb reflector
middle = wood table which divides the two rooms, has holes and 2 small pc fans exhausting air up to flower room.

The picture didn't post for some reason but that's a clearer explanation. If the air outside the room is cool/cooler (say 10F cooler), then increasing the air intake fan to a bigger/stronger inline fan could drop temps a bit. But quite frankly, for the size of the cabinet(s), using both hps and CFL's in there is asking for trouble. I'd be looking at a small COB LED for your flowering light to replace that hps and your heat problems would go away regardless of season.

Imposible to me, i cant afford one.

This could be, but the veg rooms has no temp problems, so i believe that the cfl are not generating heat in order to worry about, and the table is very thick so it doesnt get hot trough it. maybe i could completely divide the rooms, but the problem is that i would need another carbon filter, got very smelly plants even in veg!

i would rather keep the hps, i have compare hps vs led and like it more!

Then I'd be looking to replace that intake fan with double the cfm, maybe also the exhaust.

Too much heat in that small a space and not enough extraction. that HPS might be to blame!

Keep it simple- Why don't you go air cooled? OR just upgrade your extraction?

At 100 degrees I would be slow roasting pork belly in there

i dont have money and space to buy an ac... i just have the money to buy to inline fans...

Without more air-out (exhaust) or separating your 2 chambers completely (I.e different cabinet) , you're stuck with it. This is what happens when you try and go for more than you should in particular sized space. I know it all too well, guilty as charged.
just think it through and be prepared to spend some money upgrading. I guarantee you in about 18 months you'll have almost upgraded everything you currently have! It's a learning game.
