about 2 set up room.. need some advice please!

one fan will be used to cool the hoods then additional fans will be needs to keep you grow room at the temps you want and good air circulation.

Just a heads up, i always thought that you would push air through the lights but you are suppose to pull through the lights, have the ducting in an area that it can suck in air from a fresh room (not grow room) and pull it through the lights the out (preferably out of the grow room)

As for other fans two nice size ossalating (16in) should do the trick, and keeping the temps stable is a whole different game. An in and out take fan would keep temps in check or simply an ac unit does wonders.

One more thing to take into consideration is the humidity and how that will regulated.

I just recently re did my grow room with all that i have talked bout and the plants are thriving under an extra 400w and also the addition of co2. If you are looking for a monitor to regulate it all the sentenial chhc1 is the mac daddy shit but very pricey.

Best of luck starting out....hope to see it up and running soon.

i didnt want a ac unit but it seems will be worth it in the end... is that one enough

Yes you are mostly correct.

The fan for the light is going to be suckin fresh air into the hood then you would want to blow all that air out of the room. You dont want to be putting the air back into the room because that would make it harder to keep your room at a lower temp.

As for the ac unit, it may not be necessary because you are setting up shop in the basement with the in and out take fans. This SHOULD keep your temps in check if you have a way to monitor it. But always think about the humidity, bud rot is a b*tch and will f*ck up your smoking smack and we all know thats no bueno.

As for the carbon filter, you can buy one that has a fan already connected to it and you just let that run in the room solo. That is hooked up to nothing because you want to suck air in from the room and then blow it out into the room. This is just going to be cleaning the air of odor and recirculating it for good air flow. For the size room your running you will want a massive size c filter if you expect it to work. Always good to go overkill so your positive it works.

And for the in take and out take fans i have learned that you want negative pressure meaning that the out take will be more powerful than the intake. This is so you can vent your room out and get all the hot humid air replacing it with fresh air. 400 to 500 cfm intake should be just fine with the 8in vortex to take it all out.

To ensure good stable temps an ac unit could be necessary (figured that out the hard way) depending on ambient outside and inside temps. A basement is usually cooler so only you can judge that. Also an ac is an easy addition to the room if you find out that you do need it. It a lot of trail and error at times but with this set up it will take a lot of that out of the equation for sure.

HUMIDITY dont forget about that....it will make your life a lot more difficult when growing.

Best of luck to you and cant wait to see the sick set up that is in the midst. Also make sure you have enough amps per outlet before you start to set up anything that looks like a grow room. 15 amps can run 1440w safely. If you have to hire an electrician you could possible be setting up a soung studio for your band or what ever you feel comfortable saying.

If you dont already have a good tool to cut your holes the drill pro 2-12" hole cuter works like magic and makes the job a lot easier (if setting up a grow room is easy at all).

You arent planning on running co2 are you?

i am no expert when it comes to growroom setup, but mine works good and no smell outside the room, even though it REEKS like weed inside the room.

cant remember, is the room completely sealed airtight? or will there be small places where air can enter and exit besides the obviouse ducting places? imo the venting for the hoods and the venting for the room itself is 2 totally different things, unless you dont have vented hoods, then its all one big venting operation.

i sheetrocked my room, but still have small holes and areas where air can come in and out. i'm guessing this is your situation too. so for room ventilation anything around 700 cfm or above would be good. you dont need to have a fan push air into the room for room ventilation. just need to make a hole in the wall to allow air in the room from the rest of your basement. then you can get a carbon filter(10 inch or 12 inch) with a matching fan and put that at the opposite side of the room from where your room air intake hole is. get a piece of ducting to put from the outlet of the fan/filter combo and hook it to the wall to wherever you want your room air to exit. this way you have the negative pressure you want. air will come in through the hole and from one end of the room to the other go into the carbon filter, through the fan on top of the carbon filter, into the 10 or 12 inch ducting to the hole in the wall and out of the room(to outside the house, or just back into the ambient basement air-like mine)

as far as the hoods, if they are 8 inch, i would get a couple 8 in fans, one on intake and one on outtake(or mount one on in the middle of the mess). have duct hooked up to wall for an inlet for the hoods, go through all the hoods and back out the room. this keeps the air to the hoods and air to the room completely separate.

i dont need a separate ac in my room, but you have quite a bit of light/heat in there. basements are usually pretty damp so you will have to keep an eye on the humidity.

my :2cents:
 
no im not planning on running c02, maby later but not for now...

also what can i use 2 keep humidty down(the ac unit)

im going 2 have ballist outside the room and
im going 2 have a http://www.hydroempire.com/store/product_info.php/cPath/12/products_id/663 outside the room for all fans/lights

also... couldnt just cutting holes mess with the light cycles?

and i think i got it down now

i need 1 fan sucking air threw my lights 1 fan blowing air threw the lights

i need 1 fan/carbon fliter inside the room re circulating air

and a slightly smaller fan blowing air in with a slighty bigger fan sucking air out

and a few oscillating fans around the room?

and maby a ac unit if humidty needs work?

ya u have to make it so the air inlet wont let light in. and the carbon filter/fan doesnt recirculate air. well, sort of. it pulls fresh air in the room and pushes it back out filtering the smell of the room out.

are you going to have a fan pushing air into the room then? you can kill 2 birds with one stone if you use the fan on the carbon filter to clean air and to move the cool air from outside the room, into the room, and then back out.

you wont need a fan to blow air through the hoods if you are using enough power to cool them because the fan has to get air to blow out....which means its going to be sucking air through them cooling off the lights. Now if you are using 8in hoods id get two fans to cool the lights just to be safe...

Also the c filter idea that manwithname has is a good idea but id rather just run it in the room only cleaning air in the room not cleaning air from outside the room. My preference only.... his idea will work for sure if you like it.

You got the in and out take down for sure.

As for the humidity an window ac unit will work for that also keeping the temps in check all the time. A dehumi will work too just some are known to cause a some heat but heat may not be your issue...

Ossillating fans are always a must for the good air circulation....sounds like you got a good idea bout what your up to just got to trust yourself and get to it....love to hear some one embarking on there first top of the line grow room do it big.....most of all do it safely.

Also bout that hash you were talkin bout earlier, no need to waste good herb on brownies just use all your trim and make soom canna butter....also the bubble hash machine that you order from the uk is f*cking sick....some of the best hash i was tasted thats including all the different types sold in a-dam......a very good investment considerin the hash you get out of something people may just scrap....i just get a big black trash bag and freeze it between harvest times and after bout four of so harvests i make me some hash.
