It does blow pretty cold but my problem is that my tents take up most the square footage in the room and the tent is like right directly next to the window. So it blows directly on the tent and doesnt chill the room like it should.

Block all of that light from getting in. That will help with temps as well. If your register isn't where you want it to be then move it. Buy a duct outlet and some 6" flex and tape it to your current register

I thought LEDs were claimed to be cool running or at least the super duper ones.

600w HPS here and sitting nice at 82F with a lot of wiggle room should it get hotter.

nah thats a myth they sell you on. The temps maybe are like 5 deg cooler but mostly around the same. The benefit is just electric costs and light efficiency

i had them connected at first (but i wasnt venting outside). I had 6” tubing connected between both tents in the middle but i felt like it wasnt pulling enough from the second tent and i have a strong exhaust fan but i might have been wrong.

are you using 4” dryer window vent? I actually considered this before and bought the window vent with a 6” to 4” adapter but returned it

Yes it's a 4" dryer vent. My fan is turned down so low I don't worry about the flow restriction.

I'm assuming you're all talking about the ambient air temperature in the room, and not the actual temperature of the plant you're growing?

I'd suggest getting an IR thermometer. I think you'd soon realize the actual difference in temps of objects when you measure the objects themselves. (Edit: difference between objects temps, and air temps, etc.).

Also, as far as I know, window ac's are more efficient than portable ac's. Portable ac's with only one hose/duct (only exhaust, no intake) are a fucking scam - they are very inefficient, don't buy one. If a portable is what you want, get a dual hose, as the condense and evap are separate and the "hot" side is cool by outside air (not the air you just paid to cool).

I agree with the vent outside suggestion though. You could get a Y fitting and duct them both outside, or just daisy chain them as you've suggested, I think.

And I don't think trying to compare your grow room and it's conditions with someone else's who's; in a different geographical location/climate, with different lighting tech, and cooling equip, and size, and plant numbers, etc makes much sense - or at least it's probably not going to help you fine tune yours much.

Edit: RH makes a difference as well, have a look at a VPD chart - just for reference, if you haven't. Not as a guide but just as an idea maybe.

My opinion.
Good luck dude.

yeah youre right. But i do know the ambient air is the biggest issue so venting outside is probably gonna be my first step in the right direction

Is your central air unit maintained? Yearly cleaning of the evap and condenser can really make a difference in performance when it’s hot out. Sounds like every little bit with help right now, just throwing that out there.

Yep its actually a brand new unit as the building was completely rehabbed this year before i moved in. The HVAC guy checked on everything bout two months ago.

That sucks. I’m in western Canada and the poplar fuzz is killer right now, I went out about a week ago to spray my condenser down again, even worse today, drifts like snow haha. I use a separate 8000btu in a 500sq ft lung room, my temps were pretty iffy but I just scrubbed a 6” vent right to outside and it’s so much better now.

This is the solution. It helps majorly with humidity as well. I vent my veg tent into my flower tent. Then through the filter and outside with a cute little dryer vent. Like I said, i had to close my central vent to my room

Ok i hooked up the dryer window vent system. Dropped temps to around 85-90F. (They were getting 90-99F at first so def helped.

i had both tents connected i just ran a separate exhaust from the second tent to the ambient air in the room and temps were better seperatjnf the tents. So i just have a single exhaust in the other tent leading to the window Which is pulling inthe rooms ambient air as well thru the open tent flaps.

today i also put black trash bags over the window in hopes that helps with the light Leaks and heat. Unknowingly there was a small light leak due to the window and open flap.

I'm stuck this summer with temps 90-96F with as much ventilation as I can (406CFM exhausting air cooled 600W HPS dimmed to 400W and 290CFM exhausting the tent), I just flipped to flower yesterday. I'll try and update this thread with some pics, but just came to say that the only problem I 'think' I've noticed is that they grow a little slower and that they are fucking thirsty little bitches.

I don't recommend growing over 90F but I'll use myself as a case study as to whether it's even possible to get a good harvest at temps like these.

Yeah man the slow growth is an absolute pain. Dealing with it now.

I have both a window unit and central air. Its just my electric bill was getting crazy

What are you doing with all your exhaust air?

is it leaving the growing area and leaving the room with the grow located in it?

or are you dumping the air inside the room with your grow and then expecting your AC to pick up the slack?
