Quick maybe daft question

COULD I RECYCLE THE OUT TAKE AIR AND PUSH IT BK IN TO TENT INSTEAD OF OUT OF THE ROOM.

I.E AT MOMENT AIR BEEN SUCKED/FILTERED THEN BLOWN OUT OF ROOM.

CAN I SUCK THE AIR/FILTER AND BLOW BACK IN TENT. REASON I ASK GOT 1 600W ON AT MO. SECOND ONE WILL GO ON IN FEW WEEKS AND TEMP IS AT 81.C NOW WITH JUST THE ONE..

If you're already at 81ºC, I think you've answered your own question. Has the paint started to smoke yet? cn

Lol i man 81.f 32.c

Okay that's different.
IF you have a way of actively exchanging heat from the airstream, then maybe. The other thing to consider is that drawing fresh air maintains a good CO2 level.

Do you have light/hood cooling air on a separate set of duct&fan? cn

damn 81 degrees C. thats freaken hot bro... thats like 178 degrees F (im from the US). you trying to dry some ganja? If you recirculate the exhausted air you will only be putting hot air back into your room and it will never cool down. blow that shit out. good luck with that one.

I have a xxl grow tent. 6"out take with 6" carbon filter hung in top left hand corner. At opposit side i have a 6" intake fan blowin in fresh air from outside. Also i have a 12" oscolating fan on low. 1 600w with normal budgt reflctors not cool tubes or anything. My temp is at 81.f and humidity is at around 45/50%. But when secound light is on the temp will sure to rise. So can i recycle the out take air what has ben filtered or would u invest in another small intak kan say 4/5". I have 10 babies around 6 wks old just repotted them on satarday.

Easy fix. You're trapping your lamp heat in the tent if I read that right. I have a 4x4 tent, the same XXXL 6-inch hood. What I do: Draw your air from the grow space into the filter, through the hood, and out with the fan mounted outside the tent. Heat gets dumped. You can even duct the exhaust to another part of your residence or even outside.

<edit> Just re-read ... you're not running an XXXL hood. I recommend getting a closed hood and setting up as described: filter - duct - hood - duct - fan (on pull) (- duct). You'll have better heat control, since a good 3/4 of the heat is trapped by the hood and dumped into the outflow air. cn

i am growing using a 600w hps, a 12" oscilating fan at one end and an 8" fan on the other side, i also have a 6" bathroom extractor fan turned the other way up blowing fresh air in, i dont have any escape route except the fact i can open with of my doors undetected. My babies seem to be doing great my temp is a constant 85

i dont understand, if its too hot after removing the hot air ,why in fucks name would you want to return that air to the tent?

yea true chopper buds. did say might be daft question
