Found my problem need advice

Ive been trying to figure out whats happeneing i cant figure it out.
Ive used this setup for 4 yeara no problems
All ive done different is upgrade my ducting
Instead of pumping into loft with the tent it now y connects out with the carbon extraction.

That should improve it as hot air is not extracted loft feels cooler....

I run 2x 600w cooltubes and temps normaly 28ish

Ive got 1 on atm and its 29.

The negative preassure is insane. I use a twin smscom controller now...

I think it is dimming my intake down aswell making it not work well...

My fan i got the controller cause fan was too powerful and put both fans on the controller...

I found if i put a 4inch passive duct in i stilnhave neg preassure with big fan on minimum 60%
And first. Nob at max 60% so lowest settin fot max air movement.

Setting is 60 24 c 60 and neg pressure with a 4inch passive
Setting is 60 24c 100 and neg with 4inch passive.


If i took the intake off controller and run that on its own it would have more power right? As the controller runs the i take slower detault it says?


So do i just run the outtake on my controller?
Get bigger fan ewual to extraction..?
Run bigger passive with intake fan to equal it out more?

All i know is i added the passive and i put slowest fan speed to 60 outtake 100 and ive dropped a few degree im 26.7 from 28. So thinking tweaked more i could drop to 24?

Advice plz? Confusing as i only used passive before and i ran cooltubes on the carbon filter.. I thaugh it wud be no brainer running cooltube and carbon filter seperate would reduce temos ot increase the.

Negative pressure is a good thing.... You shouldnt need an "intake" fan. The exhaust fan will pull plenty of air in through the bottom vents.

Set it up like this, Fan pulls air through filter, pushes it through cool tubes and out the tent.

Ive got em set up seperately atm should work better shouldnt it?

Goin

6inch a1 cooltube cooltube out vent bathroom. Y

Bedroom in 6inch a1. Control point 1
Carbonfilter 6inch l1 out bathroom. Y control point 2



Running passive the l1 fan sucked somuch neg i was getting pinholes in the tent and bars bent in.

I reduced this by putting the a1 on the i take
(i used to use just the a1 on filter and cooltubes)
But wanted to reduce temp further. So upgraded to l1 extraction and reduced the restriction of the cooltubes by setting them up on their own fan

All calcs say i need this or less.

I got 430 in 800 out on filter its 600 with less 25

So dontget why run in like i am it should be freaking perfect im doing that plus runnin aircooled on its own

Nah i run summer every year lol summers why i did upgrades so i could cope more conformable lol but its been rainy and cold for a week now lol

You have two 430cfm fans, one is your tent intake coming from another room?
Where does the air come from on the other fan that goes into the cool tubes?
Theres a little square on the end with something written, whats that?

What is the actual air temp outside the tent and the incoming air from the other room?

You know the problem with that calculation is it doesn't take into account the ambient air temp or the amount of wattage.
It suggests a guy in Alaska would use the exact same ventilation as a guy in texas.
Its a common calculation but there is an obvious flaw there ey.

Also tell us about the last point where it exits, this vent, is it a louvered vent, a brick vent with holes, or just an 8" open hole?
