Need some help with exhaust problems for a 2000 Watt grow

[FarmDog]

OK.......I just bought my own home, so I am more comfortable with the security aspect of growing. I used to grow in rentals with a fair degree of paranoia, but now I am at ease.

Here's the scenario: I am growing with 2000 watts with MH/HPS switchable, air-cooled lights. I built a 7x8x8 grow room within an unused bedroom in the basement. I had originally planned on venting out of the fireplace chimney in the room, but I realized today the the chimney is shared with the main floor fireplace, and I am afraid it will make my whole house reek of Herb come flower time.

I have access to my furnace and my water heater duct work. I really have no idea if it feasible to use either of these methods for venting, but with 2000 watts blowing back into the room, it will heat up quickly, even in the winter.

So......does anybody know if it is possible to use my water heater duct work to vent out of? Where would it go? Could I use a carbon scrubber and just vent into my furnace, thus using the radiant heat to help heat my home?

Any help would be appreciated.

Its hard to say not being able to see the actual placement of stuff...You could just seal the room and air condition it with one of those portable floor units... Still run the scrubber through your aircooled lights to relieve the hotspot and make it more like ambient.



***ahh, i see you added pics***

I'd go ahead and vent up the chimney.

Provided you use a carbon scrubber you should have no smell concerns anyhow. Maybe invest in a Vaportek optimum 4000 for that extra piece of mind.

Its nice as you can possibly heat your living area with the heat from the lights in the winter.

Doesn't your fireplace have a means to close it off from the living area for the warmer months?

Or as suggested ..use AC/Co2 and seal the room. Then you can play mother nature w/ TOTAL control of your grow room. A bit more costly to setup..but worth it in the long run.

PS.. the hot water take out ducting would work as well. It typically ducts into a chimney pipe or right out the side of your house similar to a dryer vent hose.

hey dude

you can use that to run your hot air out of but id get a damper to stop any back draft and it will work fine i vent in and out fresh air too

 

[FarmDog]

Cool....thanx for the replies.

420KushMaster.......are you talking about using a damper if I vent into my hot water heater duct, or into the chimney?

& PonicalChillin.......I never even thought about closing off my fireplace upstairs. That should work fine as well.

i would look at the vent size, if its small (4 inch) id be worried about the fumes building up because the pipe can only hold so much air.... maybe im thinking too hard. id start by using all vented hoods. i have 2000 watts and i need an A/C to keep my room at 70-75 i dont vent my hoods though. ive been told if i do i can ditch the A/C and free up another circuit the a/c pulls 1250watts at 10 amps. a fan pulls maybe 200w at 5amps or so... maybe you could vent into your attic. or the crawl space between floors. thats what alot of my gro-friends do, asuming thers enough room.

he is correct you want a carbon filter you dont want to just blow the smell of your ladies out the chimney or roof

carbon filter!! buy one of those 5-gal pails (of carbon) off ebay and make your own!

Id use air conditioning and a vaportek 4000 for odor control,with an AC you can really control the environment night and day

vent into your attic. not out the roof. the attic is the sealed air pocket between your roof and the celing.

zerokool: sorry, but thats not the best idea. who wants to have all the snow melted off their roof in the winter when everyone else has a foot of snow layin on top? it just leads to suspicion from the neighbors and possibly popo

If youre not using the fireplace on the main floor you can get a sealing insulation blanket from home depot and seal off the fireplace coming into the living room. Seal it really well to prevent cold air / warm moist air from coming into the living room from the chimney. place some small buckets or containers of pinesol to keep the stink from coming into your living room. If anybody smells anything, it would be a faint smell of pinesol, not herb.

Sup FarmDog, congratulations on your new place and grow room. I'm definitely not an expert on construction, but I'd be careful venting out your hot water or furnace flue, in case toxic fumes back up into your room or otherwise leak.

Can you use an existing dryer vent, or create one?

Right now it looks like you've only hooked up one side of your hoods. If you sealed the glass lens, and hooked up the ventilation so that cold air from outside the grow space is used to cool the lights, you could then use that air to heat your home since the exhaust air has never been in the grow room. You wouldn't need a C scrubber on that exhaust. But you should probably have another scrubbed exhaust creating negative air pressure in the room.

shit man no one mentioned snow.
plus that was is 500X CMEMORYER then carbon BS vapor nonsence and ozone whatevers. what a tube fan and soem tube ? shit. i doubt itll be that outragous, ive got 2000 watts its not that hot.

 

[FarmDog]

Thanks for all the helpful replies. I might not have been too clear on where the exhaust is going. The water heater vent goes right up the chimney and outside on top of the roof. I don't think anybody would smell the herb, unless they were hanging out on my roof.

However, I added some new pics to help explain what I wanna do. I have a 6 in. CFM fan the vents my 2 1000 watt lights and so far blows the hot air back into the room. I just wanna take this hot air and blow it up the water heater vent. (SEE PICS)

I also just installed my Co2 controller. When the Co2 isn't on, and the CFM fan isn't running, will the hot air from the water heater enter my room through the hoods and enter the grow room? If it does, isn't it just hot air enriched with more Co2?

I also installed a small 4 in. CFM fan for fresh air to come in through a window.

So.....whaddya think? Will it work?

 

[Kush King]

looks like she should -_- wouldnt worrey about the hot air comming in.

looks like your on the way to sum dank buds
