Yeah, heat issues are a whole new set of headaches. My veg tent seems to have finally leveled out around 82-84 lights on, dropping to the mid 60's(66) during lights off. Flowering, i dunno at the moment, cause I need a new thermometer, but if I had to guess I'd say below 90...lol

Haha, don't listen to me, i'm doing things the idiot way...lol...I run things backwards from the norm, with forced INTAKE and passive exhaust. I have 1 standard off the shelf fan for each area near the floor blowing in, and I cut passive exhaust on the top corner of my tents with light traps. I also have a fan INSIDE the flowering tent for air circulation, and soon gonna add another to the veg tent. The intake fans run 24/7 and the circulation fans are set to run on the timer with the lights. For now this is working out. I reckon that once summer rolls around i'll be singing a different tune though, but by then i'll probably have switched things around to the "normal" way, forced exhaust, passive intake. Actually, i think the forced intake works well. I have a curtain seperating my grow tents from the rest of my room, so my issue is that the "room" my tents are in heat up unless I remove the curtain seperating the tents from the rest of the room. So my tents are recirculating hot air 
Cant cool your grow cab when you're pulling air from a hot room. So now I just leave the curtain drawn halfway when I leave, and open it all the way whilst home. It's chillin at 79-80 right now and I couldn't be happier.

that is very cool man. good deets. i think at first i'm gonna have a very similar setup, a (nearly) passive exhaust (the trueair fan) and a regular desk fan blowing air in. i have a similar situation with my closet as you have with your screened room. if i close the closet door, it gets hotter in there, so i leave it open whilst i'm home but my girlfriend isn't lol (cause she doesn't like the smell). so it's mostly closed during the day and always closed at night for darkness. oscillating fan blows on schedule, true air on all the time.. get's up to the the low 80s in this time of year up in the bay area. i'm sure the box will get hotter, how much hotter is the question!? anyway, i will have lots of questions in the next couple days so stay tuned!! haha, but seriously thanks for the suggestions.
by the way for my summer grow, i'm gonna try switching the day/night cycle to keep temps more balanced....

Yeah, first off, you can leave that closet open at night with your new box, just make the new box light tight. You're gonna want to do that to make your ventilation effective anyway, as airtight as possible. Veg tent runs from 11AM to 5AM (18 hours) and my flower cab is going from 5PM to 5AM, so I'm already pretty much on a night schedule for summer, or only minor tweaking of the schedules necessary. The fans I use for intake have solid plastic around the sides, not perforated, and I cut a hole in my plastic and tape the fan in there so it's airtight. I set this all up in the middle of winter, so it was a battle to find small fans, and once summer comes I just need to figure out how to cool my room, seeing as I don't have AC. I have some ideas though...

No cheap PC fans here, I'm using an "Air Circulator" from Target, like 16 bucks. Thing is loud, but blows air like a hurricane. The other fan i'm using is AWESOME, some little personal desk fan that is small, quiet, AND works well! I stole it from a family member and have absolutely no idea where it came from.

ok bra, just read the first page of your thread in detail. your vent system is working well you say? if so i think i'm gonna copy your setup! my oscillating fan is very similar to your air circulator. then for "passive exhaust" i might just aim the vent out into the true air fan. i'm kind of afraid that if i duct it the trueair to the exhaust vent it won't be able to pull air out as fast as it needs to, and the air will leak out elsewhere... maybe i'm wrong about that? i guess it depends on how air tight the box is... hm, this is gonna be a project. glad to have your help bro, take it easy.

Just make sure whatever exhaust you have is at least equal to if not larger than intake, that is the flaw of passive exhaust and forced intake, not as efficient. Page one of my thread is a far cry from my setup now, and the ducting ended up hindering air flow so I got rid of it. I'm here if you need anything.

thanks bro for the support. what do you think of this fan for exhaust?

very cheap ($16). 50 cfm is not a lot but in combination with my trueair and relatively small box, it might be enough. i like that it has a 3-inch duct so i could cut a small hole in the box, put the fan inside the box, and attach a carbon filter on the outside. they also have a 70 cfm version for $28.
another option is to get a second true air and hope that between the two they pull enough air out of the box. the one i have is the basic one-speed model:

but maybe get this is a second exhaust:

hey guys, i started setting up my shorty wardrobe box from uhaul. it's 21" x 24" x 36" (height), a little smallish but unbeatable price ($8, lol).
first i cut out a door... here's what the plants look like inside
i installed the t5 pully system, so that's cool...
i measured stuff up with the t5-hangers, and i have 25" of vertical space from the floor to the lights at their highest. the pots are 9" tall, which means my plants can get to about 15" above the top of the pot, maximum. i think that will be doable.
so i'm only about 1/3 of the way done setting this thing up. tomorrow is a big shopping day, i will be getting some wallpaper-ish things, velcro, a couple light sockets, and fan / filter items. i might get a couple of pc fans and try to make my own carbon filter, OR get another trueair fan and use two of them for exhaust (and one pc fan for intake). i would use my oscillating fan for intake, but i don't know if it's a good idea to make such a big of a hole for it... in all likelihood, i will be learn how to wire a pc fan tomorrow, woo-hoo!
anyhooooooooooooooooo............... i had some "aff goo" tonight, awesome stuff, real chill.

sure man, i have my true air sitting right under that defuser box. you could probably just put a carbon filter across the botton so that the exhaust air blows through it. you should be able to rig up the T A like half in the box and half out, should work.

yeah, that's exactly what i was thinking with the true air things initially (half in half out). depending what deals i can find tomorrow driving around town, i'm gonna choose either option (a): 2 trueair filters pulling air through their own carbon filters and pushing air out, or option (b): a 10-inch fan that blows into a carbon filter, but then i'll have to actually make one.... hmm... do you think the trueair replacement filters could work? thanks bro
