Ventilation question (with picture)

Ok, so a brief background on the room itself: 2x6x8 closet, with a shelf in the middle separating it (in the picture it's almost centered, i'll probably move it up another foot or so so give the flowering room (bottom) more room). I'm gonna have 2 fans in the shelf itself, with covers and filters to prevent light leaks. One is going to be intake and the other exhaust so the air can be shared between the 2 halves...i'm gonna have a main intake into the room split with a Y adapter so my 1000hps can also be cooled. To finish the air flow on the light, i'll have ducting going through the shelf up into the attic with another Y at the end for a main exhaust.

What i'm trying to find out, is if this will work...this isn't my first grow, but i've never had proper ventilation in my past grows.

The picture is a rough cad drawing further edited in MS Paint (I know, i'm super savvy with software ;-))

Here are a couple photos of the room itself. It's kind of a mess right now, but that's it....I'll be patching all the holes and repainting before I start the grow. i'll be adding locks and weather stripping to the door.

I'm thinking a smaller bubbleponics SOG since height is sort of an issue. i'll probably have between 6-12 plants flowering at a time, with a couple mothers and multiple clones in the space above.

I'd love some feedback!! Maybe you've got different ideas? I haven't purchased that much equipment yet. the light is from a past grow, I still need more fans, another squirrel fan, and pretty much the entire grow setup. I would really like some suggestions on ventilation, or if you think im on the right track (be honest ;-P) let me know! :joint:

air cool your light.
co2 enrich your room.
use a fan for circulation.

no ventilation needed.

I'll be using a 1000w HPS for the flowering room, and just CFL's for the mothers/vegging. I'll be adding an additional fan in each half for more circulation, cooling, and to add strength to plants

Edit: the 1000w HPS has an external ballast that will be in a separate room

Well, i'd rather it be done right than just enough - if ventilation isn't necessary, should I remove the Y at the intake/exhaust and call it a day?

Well, I could remove the Y's and add a 2nd intake and exhaust? the idea behind the Y's was so I didn't have to buy 2 additional fans. Will adding the Y's be enough? Or maybe i'm just thinking about this all wrong? I'd really like some insight. Thanks guys :D

Depending on the size of your fans cfm ?? you might only need one for the light and you can use the other for the rooms intake.....

...... if not just buy a cheap fan for the intake and use the other two for the light

......or buy a new fan and us that for the light and use the other for the room






Put the intake on the bottom of the room

I only have 1 fan right now, it's an in-line 4", 80cfm fan. I'm not too familiar with fans and CFM, is that a lot? when I buy the next few should I buy bigger ones? i'd be willing to upgrade to 6" if you it's dubbed necessary...thanks for your input =)

That 4'' fan would be ok for your room intake (maybe) but for the light setup you need more ..... its going to cost you just to let you know ....... i dont know where you live but if you have a hydro store go buy a canfan or a nice big fan or check the web theres allot of different stores online. I hooked up two pc fans cost me about 60 bucks for 2 PC 4” fans 170cfm

Also, i'm not using a cool tube..just a regular reflector with a glass bottom

Shit man you could use that but i believe that's a squirrel fan and they are loud as fuck and shake allot ..... not to sure about that one but i know when i was buying mine noise was a big problem ...... i had to make that sound-box for the can-fan i got.... link on bottom of page

Haha I was already thinking about a box for noise control =)

hmm, some of those fans are stupid expensive - there actually is a hydro store near me, i'll check out what they have...although I'm guessing the prices there aren't going to be any better. I think i'll incorporate the PC fan idea into the shelf in the middle so air can flow between the 2 halves..but im thinking 120v fans instead of 12v for simplicity.

So, I think what I'll do is get a squirrel fan or can-fan to cool the light, and either a 2nd one of equal power or slightly less for intake to the room. Build a box for both to lessen the noise, and uhh...call it a day. That should do it I guess =)

Thanks guys, you've been a huge help with the brainstorming

My local hydro store (according to their website) carry's these http://www.hydrofarm.com/pb_detail.php?itemid=6606

for 119.95. I found them for 10 bucks cheaper from other online stores, but I think I'd rather support the local shop (and not have to pay shipping)

For that price i'll probably just get 2 identical ones and rig up a noise box for 'em. It'll be sweet =)
