I had the same issue. I figure your running lights at night already as I did.. if you have axcess to outside or even better yet UNDERNEATH the house from any spot relatively close to the closet you can set up an inline fan.. or I used an inflatables blower for power.. and then pump the cool air into your grow space with hvac hosing. Took my temps down majorly

Yea one with the hose in the back for exhaust. I was thinking I could work the exhaust hose into a 6" exhaust flange out the top. My question is should I rig the a.c. exhaust to a filter.

Hey johnei, I took out the 6" reducer on my 8" exhaust fan. My thinking being less restriction= more cfm. I also eliminated a 90* turn. The results are 84 under direct light top of canopy on one side and 77 ambient temp.Reason why I say look to changing passive intake to be actually powered the first thing to do of maybe a few things you'll have to do is because most can't just change out their exhaust for a bigger one or turn theirs up higher than the high ya know.
The first thing I would actually do is increase the size of the passive intake; small size at first and keep testing results so not to make it too big before actually putting a blower n there.
And last thought, I flower all the time in up to about 84'F with same type of setup with all kinds of different strains, exhaust up high sucking air out 24/7 and passive intakes and always pulled good yield numbers with no issues. Monster rock hard nugs. Airflow is key and fans moving the leaves without wind burning them. When the leaves are moving around not stationary, light doesn't sit beaming in one spot and ambient air temp isn't the killer, with all the airflow and wind and movement as long as a lot of new air is coming in. Right now I'm vegging at 79-81 and it's fine. So I don't think yours numbers you just mentioned are that bad. The 86-90+ is not good.(without co2)
Grow on.
If I go active do I just run the fan and duct or do I need a controller for the fan.

in my opinon, you'd only need a controller on the incoming air if you were pulling some super cold air and didn't wanna over do it with cold, at nigh lights out for example and things like that. Each setup and location is different so can't answer you with a definitive answer about that one bro. To be fair, I run passive intake not powered, with good exhaust fan and not huge room.. intake air pressure from exhaust does the job. air is exchanged no stagnant shit. Only in a larger room need fan pressure at the intake because exhaust that in not HUGE wont be able to exchange the air well enough, so it needs help at the intake in my opinon, but so many variables, everybody and every place is different.
84 at the center but 77 everywhere else, try to keep the shorter girls under the middle, and direct heat from the lamp will kill humidity in that region also, if you could without losing too much intensity maybe raise the lamp, maybe you are testing way too close, all lamps are fuckin crazy hot, the 84 in the center where you tested is that the same height and spot where the plant would be sitting you sure you didn't test too high up where plant actually would not be? Make a stadium type progression tallest on the outside, shorter in the middle or even train/prune them like that before flower.. i dunno man. I grow in 84 all the time.. lol
Talking about exhausts and intakes, just some blahblah for ya.. I have 2 exhaust fans, 1 dumping outside, 1 dumping into room where other sits, double filter protection.
and they have been running 24hrs a day for 14years. Elicient Fans baby! best shit I ever bought, 8" and stronger 6" model cuz there's two 6" models... lol.. they've only ever been off for like a day here n there when moving and shit like that.
Neg. pressure smoking protection as well.. every crack every door everything sucks towards those filter/fans.. nothing can escape.

I'm actually running dual 600s. I do have that thermometer only 8 or 10" away lol and in direct light. But glass is cool to the touch. When I move it the temps change a degree or 2 for the better so I think I got it.in my opinon, you'd only need a controller on the incoming air if you were pulling some super cold air and didn't wanna over do it with cold, at nigh lights out for example and things like that.

On a side note I have done 84 flower. My last run went pretty well. It was between 79 and 84 lights in. Good density good smoke.

Ac exhaust to a filter, I never smelled anything from mine, I'd say no.

Thank you lion, that's what I was thinking. Do you grow In a sealed room by chance? Seems sealed + ac + co2 would work decently well together for some big buds. Still figuring how that works though.

Seal it off and run c02.

Just came across this unit today. Give it a look, the air circulation *should* be sealed so there shouldn't be any concerns about odors leaking out. Its the Climate Right 5000 (RIU won't let me link to it). It sits outside the room and has two ducts. The first duct draws air out of the room and into the unit where it is cooled, then it is blown through the second duct back into the room. Haven't seen anything like it. Would be compatible with CO2 systems as well since it is a sealed system. I suspect other companies may catch on and start making competing products cause I think this thing is awesome!

Nope, just a 10x10 or so basement room. Room temp is 75f at night, 81f day. Each tent is about the same fluctuation. Don't need AC yet.

Yeah man seriously, do what this guy says. It costs you a pretty penny, but oh man is it worth it.Seal it off and run c02.
Since July, my outside temps have been 100 degrees minimum, the hottest day of the year was around 128 degrees and that entire week the averages were 115-120. My 4400 watt grow however, was at a steady 80-81 degrees day/70 degrees night running 1200ppm of CO2 the entire time. I have 2 15,000 BTU window units cooling the room, my electric bill was around $800 and that was with cutting veg down by 2 weeks. But seeing how much the girls are loving the temps makes it well worth it, hell they're cooler and more comfortable than I am in the day! That's just the price you gotta pay though if you want to grow through the summer, I know of some growers that actually shut down during the summer because they just don't want to spend the money on the cooling! What a lot of people forget to consider is that you're paying a premium in electricity during the summer if you're growing because everyone else is running their air conditioners so in most places you'll be spending a lot more per kW in the summer than you would in the winter.
Gotta have air conditioning no matter what in my opinion. Doesn't mean you have to use it necessarily, but having the option is always nice. That way if things suddenly end up becoming too much for your fans you can have the air conditioner pick up the slack on those brutally hot days. I'm thinking that during the winter once things start cooling down, one single air conditioner should be good enough for me. I almost thought 30k BTU cooling was overkill when I was spending the money, but man once summer hit and temps got over $100 I was so thankful I did.
I definitely recommend looking into a sealed CO2 grow though, I'm in the middle of my first one and I'm never looking back. Your set up looked very nice for sure, from what I'm seeing you look pretty damn dialed in actually. With what you posted, I might even argue it'd be a waste not to supplement with CO2. It can be a pretty pricey endeavor, but once you see the results you'll be so happy you did it.

Lets see. I have the ac. Plus a way to cool my lights independently. Sealing the room shouldn't be too hard. Just some caulk and foam sealer should do the trick? Panda film + a zipper for the door?
Am I on the right path.
As far as co2 for my small space, would a tank Set up be better (cost effective) than say a burner setup? I never really get scared of putting money back into the op, just a tad more concerned with effeciency.
Thanks everyone for your replys.

Essentially yeah, looks like you've got yourself a wooden room/frame going on at the moment? Kind of hard to tell with the one picture you have up. Assuming you do have a wooden frame though, you're on the right track with the foam sealer but that's only half of it. Definitely hit all of your cracks with either caulk or foam for those large gaps, then look into getting yourself some insulation. I spent a good $400 or so on insulating my 10x16 shed but it was well worth every penny, R13 in the walls and R19 in the roof.
As for the CO2, I'm a bit biased toward the generators myself. They're a bit more costly, but it's a hell of a lot easier filling propane tanks than it is CO2 tanks. Much more discreet as well.

I cut a perfect a/c port in my wall its ghetto but it works and its small and efficient don't kno if you can just cut a big ass hole in your wall but I'm a commercial painter as well so I just patch it when I'm done and texture my wall where the whole was and just paint it its like 15 bucks to fix my wall when I do fix it haven't in 2 yrs but I use to fix it after every grow people would ask what's that for just my way not saying cut your wall
