Attic setup would this work PLease check out

[nuggiespl]

I would like to set up a grow room in the attic from my research the temps seem to be the biggest problem. I would tap in to the my central heating and air supply for the intake and run the exhaust back to the return air. I look at it like adding an additional room to the house, just in the attic. I would first use plywood 5/8 and just screw to the rafters then on the inside possibly sheet rock or use the white/black plastic and the outside put insulation. Do you think my temps would be manageable attacking them this way in the summer it can get 100+, winter mid to high 30s for the lows. See ghetto drawing for better Idea the roof slopes down as you can see.I would use 400 hps for flowering and cfls for veg, i would also seal small area for veg space.There would also be 2 fans oscillating atleast one in each room. any help would be greatly appreciated
Thanks

sould work if you can tap off your heat and ac but that might be a problem because of the temps up and down stairs if your thermostat is in the living room and its hot as hell up in the attic it could be 72 downstairs whitch would make your air cut off if thats what its set two but the upstairs will probly hotter than the down stairs you might have to put it on 60 to get it cold enough in the attic get what im sayin

if that is the case you can always put an window unit in during the winter and a heater in the winter

ur probley better to try to tap off your ac system but your always gonna need constant air flow no matter what you do make it close to 75 thats perfect if you ask me!!!

I'd look into getting a heat-resistant strain like mandala's. That's the route I'm taking with my attic grow, although to be honest i haven't had any problem growing big bud or lowryder 2 in there either.

thats also an easyier and cheaper way!!!!!

:S2:

OK - I'm sorry. It's just that this obviously isn't very well thought out. :wtf3:

If you exhaust your grow room into the return air, the entire fucking house is going to smell like pot!

Doh!

Ant that's a problem WHY? HAHAHAHA I don't have to spend any money on fucking Yankee Candle... my house smells like sweet sweet candy goodness!

Exhausting back to return air is just inefficient. Exhaust to outdoors.

bad question to ask of someone named 'StinkyAttic' :S2: ... btw, Stinky, my 'Daddys Girls' tests germinated very quickly, nice and viable :thumbsup:

give him a break thats why he was asking guys

You are likely still going to have problems. You're right, your biggest problem will be heatloss and heatgain.
The biggest problem is that you are more likely to have just one thermostat and your heating/ac is not 'zoned', which means you cannot control each zone or each room. Your T-stat (thermostat) for your house is probably in the hallway or in the living room, and your a/c system is regulated by that. If you did not run your a/c for say a full day, your temp in the living room (or wherever the t-stat is) might be 95F. The temp in the attic will likely be in the 130F range. So if you ran your a/c, and you set it for 75F, when your living room has dropped 20 degrees, it will turn off. Meanwhile up in the attic, your temp will drop maybe only 15-20 degrees, and your temp will still be well over 100F. You will need to install baffles in your supply lines to adjust the air going to the rest of the house (giving less cold air there, so that your attic has a chance to cool further. Actually the best way to do this is to run a whole new trunkline right from your airhandler/furnace up to the attic, and then have a baffle to let less cold air into the remaining house. It will need constant adjustment, as the different temperatures outside will dictate. It is really not a job an amateur can do. In fact I would not do it at all. I would set up a seperate a/c system just for your room up there. It will be much simpler.

Thanks smokingbuds21, So do carbon scrubbers work or just kinda reduce the smell I was counting on the scrubber to remove the scent, it would actually be easier to vent to the outside. Thanks for the comment "not very well thought out" real mature. Thats why I asked for feedback. I was thinking of adding a couple attic fans to help reduce the temps in the attic. I am novice to growing but definitely not making stuff used to be a carpenter and electrician.

I was also thinking by putting an 8 in fan before my intake so when the AC wasn't running it would be sucking cooler air ( air from the house) 24-7, that combined with the attic fans should reduce the temps in the attic. What would be best to insulate with, I was thinking insulation on the outside of room.

Dude - I was not laughing at YOU - I was laughing at the idea - and I offhandedly blamed it on being stoned. So don't be so thin-skinned. It was meant in jest. A simple "Doh" on your part and we all would have laughed together and then got with ideas for your attic.

... But no one here is laughing at you and I apologize if I made it seem so.

No worries thanks

It has been my experience that a plant with a very well-developed root system that's given plenty of water will be the most heat-resistant. I have one plant (Nirvana Big Bud) in ten gallons of dirt right now, and even though the temperatures are often well over 100 degrees, she's shown no signs of stress. My guess is that she keeps cool the same way us people do: by sweating. :) And like us, she needs to drink a lot. Whenever two leaves are against each other, there's always lots of condensation between them, so I know that she's taking in all that water I dump in her pot.

This has only been my experience, although I've heard evidence from other growers that this is the case. It would still be important to have good ventilation so that all that water vapor goes somewhere.

What type of material would be the best insulatorl, I was thinking about 5/8 plywood and then 1/2 Sheetrock on the inside. then putting some sort of insulation on the outside. Or should I just use the plywood with Black and white plastic stapled to the plywood any help would be greatly appreciated. Thanks

Personally, I would frame walls (build walls from 2x4's) and work from there. Then you could insulate the walls. So, going from inside of the growroom to outside you would have plywood, framed wall with insulation, drywall.

If you aren't a very good carpenter, use steel studs & track. You can fuck up with that stuff all day long and all you have to do is revese your drill motor to correct your mistakes.

Before you do any framing, decide what you want to do about a/c because you will probably need a hole for an a/c unit, or for a vent, built into the wall.
