they work!...well kinda....but they are nice to make sure your air is circulating well, & dont have any hot/cold spots

Little update.
Light ventilation is all wrapped up....finally....had alot of work outside that I cant show pictures of unfortunately. Next step is wall fans, can filter, & putting the multiflow system in place. Ive decided to go with 36 sites to give them room to spread out. all my past rooms have been so packed full I want to try something different & see how it turns out.
****another note on AC.....anyone have any recommendations on ac size? 6k watts, in 12x12 with co2. Would probably like to do an ac that can be vented out of a 4 or 6in duct if possible vented out of the left side of the window in pictures below. If you have some ways, or threads that you can point me towards please do. Im not against ripping apart a window unit if I can make it work better than a stand alone $500 unit.
Little bit of oil I just whipped up!!!!!!

tried a test for about 20 mins with lights on & fan on....started at 70deg, after 20 mins was at 69deg....outside temps were in the lower 50's. Problem was at 20 mins I figured id go outside to feel the temp of the exhaust air and it looked like a street light.....FORGOT TO PAINT THE INTERIOR OF THE EXIT DUCT BLACK!..doh! huge light leakage!.....hopefully fix that tomorrow & try a longer test.
Also if any of you are having inline fan noise problems, may I suggest maxfans.....in the room, they are quieter than a normal box fan....but at the intake/exhaust you still have to take precautions due to air movement

Insulating the ducting works wonders vs. non-insulated, at least with flexi.

Nice setup Mr Weekend. Like the new room. I myself am also new to doing sealed rooms with CO2 instead of neg pressure, but I've ran a few crops now, and I still can't keep my humidity up, LOL!
I am doing RDWC buckets on chillers, and honestly, those chillers work as dehueys. I also have 2 portable one-ton AC units. I am also in the same dry climate as you, and even when my girls are seriously drinking and transpiring, I don't really have high humidity.
I do recommend AC, you can calculate how much you need by figuring out how many BTUs you will be pushing into the room. Each light, non-air cooled, gives off between 3500-3700 BTUs, to be safe, if you are ducting the lights, you still want to figure each light at just under 3000 BTUs, multiplied by how many lights you have, and then find an AC (or 2) that is equivalent to that number. As far as chillers, I highly recommend them in DWC, but if you are doing ebb & flow or something like that, they are far less necessary, especially if you are in a basement with concrete flooring.
Also, how are you generating CO2? Tanks? Natural Gas? Propane? I don't recommend getting the CAP natural gas CO2 generator, since it gets seriously HOT. I think its hydrologic that makes a propane CO2 burner that you can liquid cool with a chiller, which will help a ton, and burning propane tanks is much more efficient than hauling in CO2 tanks. Also, there is a kit for the same propane burner to convert it to run on natural gas, so you don't need a tank at all!
I also would suggest sometime of CO2/Temperature/Humidity controller. I have a CAP XGC-01e and it works great. I run both AC units (with relays) and my CO2 on it, and keeps most of my vitals where I need 'em.
Also, I love the rigid duct, but for the lights? If you are growing different strains, you will have to raise different lights at different heights, won't you? I do, which is why I use insulated flex with just a bit of slack between my lights, so I can raise the lights a little higher for those sativas!!!
Good luck and happy harvesting!
BTW, check out the thread in my sig for how I did my sealed room, err....tent!

And, oh yea, the recirculating carbon filter works great, you just might want to have more than one! That was one thing I was worried about also when I switched to a sealed room!
Seems like the trick to combating the humidity in a sealed room in CO w/o a dehumidifier is spacing your plants out well, and lots of good circulation. The recirculating charcoal filters are good for CO2 circulation also, since CO2 is heavy and sinks, the fan on the charcoal filter will pull air from below and push it upwards. I would run all your CO2 air line higher up, also!

am still deciding on where to put my filter...either hanging from the ceiling, or in a corner........I was planning running my co2 line to the filter/fan and letting it blow it around.

I use the multiflow type of bucket system as well. With these systems less is more. 
I tried the 36 site and later knocked it back to 12 and was actually able to harvast about the same amount with only an extra week of veg. I find that 6 buckets per 1000w is the sweet spot. So it seems like you are already doing it that way, you will be pleased with the results.

Raphael - Thanks & yea I cant wait!
Nice!...thats what I want to hear.....I spaced out the 36 last night & it just looked right.....like I said my other room was just PACKED, so hopefully I can space this room alittle better

Sorry you quoted me before I could edit my post. Just to clear things up. I first said an extra 2 weeks veg, when I actually meant 2 weeks veg total, which was 1 week extra for me.
day 1
1 week
2 weeks
4 weeks total, 2 weeks 12/12

I was saying that with the reduced number of plants, to obtain the same weight I got with the 36 site system I had to veg an extra week. Post #52 (posted by you) in this thread originally had me quoted saying an extra 2 weeks. I was editing my post to say 1 extra week instead, but you had already quoted and replied to me before I could save it. Your quote reflects what I changed it to though. I guess I'm the only person who noticed it lol.

Gotta love those 10" max fans they move quite a bit of air.
MrWeekend
Member
YES THEY DO!....and VERY QUIET!!!!!!!......2 10in max fans is less noise than 1 8in vortex.....wont buy anything else from now on....max fan only!
