Heat issues in my closet

I'm currently running a 400 mh
Average temps of 86-89 when light on
My closet is 5x5
I just ordered a 1000 watt light.
Now after the fact im worried about temps.
I'm running cool tube reflectors with a fan filter combo.
I have a 2 in pvc pipe with 2 90degree bends drawing in air from my bedroom
A fan inside oscillating to keep air moving.
My fan is at the top of my closet above the lightdrawing IN hot air
Pushing it over the bulb and into the car on filter
The filter is outside of the room
I knocked a hole in the wall ran myducting thru it and hooked up my filter so theheatshould be exhausted out of the room.

My issue is if im hitting close to 90 with a400 what's it going to do with a 1k?
I moved a window air conditioner into my bedroom to try to lower my ambient temps in the room.
I need advice and help.
I'm considering taping a 2 inch hose to my a.c. unit and taping the other end to my passive intake port but that would be .Lose to 20 feet the cold as of would need to move thru .
I'm still in veg.
Don't know if the pics will load

first of all your filter is backwards. put the can in your growroom and suck air out of the house. if you blow your recycled hot air just out of the growroom and it goes back in you arent removing any heat. you are heating it up more.

If I do it that way how will the filter clean the smell? If I'm drawing in air from the bedroom running it over the light and into the filter how does the odor get into the filter?

dude. the carbon filter is designed to go inside your grow room. the white thing you put around it is a DUST FILTER that keeps dust from getting caught in the filter. you are running it COMPLETELY BACKWARDS. then you duct it OUTSIDE the ROOM to your inline fan then duct it OUT the HOUSE not INTO THE ROOM DIRECTLY OUTSIDE YOUR GROW ROOM TO GO BACK IN.

sorry for caps but this is the definition of breaking it down barney style.

if you circulate your hot air through your carbon filter and blow it back in your bedroom or whatever do you think your bedroom is gonna cool that air off before it hits your light again? no its gonna keep getting hotter unless you remove it from the house completely. you wont even be able to use you 1kw. you should read up before spending money next time.

I had a small tent in my closet. The problem is the heat. I did have the filter in the tent but you need to expel the hot air out of the tent (and not into the closet). Or the air gets hotter and hotter. I now just use that tent to veg where the light power is greatly reduced and a 4 x 4 in a cooler place where i can run 600 watts of cob/CMH.

I may rethink the closet tent if i can duct the heat outside but i think there is little else you can do unless you are growing very small and do not care about the odor.

I grow inside a tent so until I decide to build a room, no co2 for me. Even before I ran Quantum Boards when I ran MH's & HPS I still never needed to vent the hot air outside.

But with that being said, my grow was a one lighter and I'm a creative type of dude. I went into growing with a full understanding of how heat is the enemy. I tisk tisk from time to time when I come across grows where people obviously didn't do their homework before they started building. I made that mistake once and vowed to never do it again.

yeah, I got out of the tent and built the room in the garage on the nice cold floor. I sputter my exhaust 4 mins on 15 mins off to keep my humidity up. doesnt even effect the temp. 81 degrees max with it off for 2 hours. Love my quantum pucks...
but ya i hear you on that one....

I jumped into DWC without reading and THREW HUMIC ACID IN THERE and had a BAD TIME. lol

round 2. FIGHT

No. I just keep my grow area at a cool temperature. Typical ambient temperature is 65-70 degrees at night, and 70-75 degrees during the day. When I crank my lights up all the way it raises the temperature inside the tent about 6-8 degrees.

I suppose logistics play a big part how to deal with heat. Years ago when I grew in an upper level apartment I used a window AC unit to keep the room cool. Nowadays I don't have to deal with all that shit.

But also - I grow small scale so containing and dealing with heat is a lot easier for a guy like me. When you scale up to multiple lights and room, I think you're absolutely right about needing to vent outside the home.

I put my tent in the basement where the cold sinks no matter what i do. And with a 315 CMH i hit 25.5 C and when i add 200 watts of vero i hit 30. And that is with a 6 inch scrubber full power all the time.
In my closet i ran the 200 watts of vero and would hit 29 at full blast and would turn it down to about 150 to maintain a reasonable temp. But wow that closet was hot inside.

I will make a room in the basement for both tents so i can get around it (and i have 2 circuits of 15 amp dedicated and wired in already).

Basements are awesome for tents.

Wait I tho k im making a misunderstanding.

By fan above the light i mean my inline fan drawing in "hot air" from inside my closet.
I'm not drawing in hot air from another source.
My fan is drawing in air from the top of the closet
Pushing it over the light then out the filter.
The filter is outside of the closet
So that it isn't just recirculating the hot air inside the closet.
The passive intake is drawing air into the bottom of the closet from my bedroom
Which has an a/c unit in itkeeping my bedroom in the low 70's.

I'm not understanding how this is afdingheat to my room.
But im here for advice so not going to argue
I switched it around
Knocked a hole in the ceiling of the closet am venting into the attic.
Pulling air thru filter- into light- out of light into squirrel fan- up into the attic
I am making a lightbox to put over the hole i had originally had the carbon filtercoming out of will now draw in cool air dfrom the a/c in my bedroom.
I ran outofducting so the side thefilterwill be on is empty.
I will put the filter near the exhaust in the ceiling in that milk crate.
  • Do I have it right now?
