BIG GROW -how practical is this?

[bongerstonerd00d]

In my house I have a gas forced air furnace that is vented from my basement to my roof, so it does not kill me off as I sleep. Now, what I am wondering is if I were to tap into that vent line in the attic on its way to the roof vent could I blow that "wasted CO2" into my grow room in the winter and not kill myself ?

I know that some CO2 generators use natural gas to make CO2, so I am curious if I have a free source of it and not realizing it. As far as cost, I may need to spend 300-400 bucks at the very most. All I would need is a "T", another length of flexible duct, and probably 2 inline fans. One to suck it from the vent line, and one to keep it moving into grow space. Could hook a probe from grow room to CO2 monitor thingie with both fans hooked to it and only have them suck if level drops below 1500 ppm. If furnace isnt on, it gets cool air, if it is, it gets CO2. I like this idea.

In the summer I would use the bottled CO2 of course, but I could probably get 6-7 months worth free if y'all think the concetration would be enuf in the emission from the furnace.

Maybe many of us are sittin on a source of CO2 that we didnt even know about.

Any thots or ideas are appreciated.

Dont be part of the problem, be the one who finds the solution:rasta:

you may be much better off just using a refrigerated window ac unit. then you can keep your room sealed. figure about 3500btu of heat per thousand watts of light. the other thing you need to consider when doing a grown that large in a room in a house, is the electrical supply. how are you going to supply juice to all of your equipment. with that type of grow, lights, fans, etc, your probably going to be in the neighborhood of about 45 to 50 amps of electricity. none of this is a problem if you run a subpanel from your main panel. my room has a hundred amp sub panel in it. with all the lights, ac, circulating fans, hydro, going i'm pulling roughly 68 amps when flowering. i'm getting ready to order enough lights to set up two more flowering rooms. this time around i'm switching to the electronic digital ballast lights. i'm going to use six hundreds all the way on the outside, and a couple thousands in the center. i'm still going to keep the same amount of wattage. i've been screwing around with a six hundred watt, and a thousand watt light, for the last couple of weeks. both of these are the new electronic digital ballasts. so far, they are consistently using about 28% less juice than the conventional ballasts i've been using. not to mention, they're light as hell compared to the others. i'll try to steal my buddies digital camera this weekend and i'll post some pics of my room if you want. my plants right now are thirty eight days into flower and are about six and a half feet tall.imp:

HEy Bonger...

Let me see if I understand this...
You want the exhaust from your furnace to pass through your grow room as it travels out of your house....

Now it just travels from your basement out the roof.. but you wish for it to enter your grow room first and then out the roof...

Is your grow room sealed?
Air tight?

SOunds doable.. sounds like you better do it right..
LOL..

hey bonger, your theory is correct, but there is no way for you to regulate the amount of co2 your pumping into your room. most modern furnaces burn fairly clean, but i'm not so sure i would take the chance of offing myself like that. also keep in mind your also pumping a shit load of heat into the room. spend the money on a good co2 set up, much safer. also, make sure your room is sealed real good, and install a carbon monoxide detector somewhere around where you sleep. i use two seperate monitors just because i'm a little paranoid. :stoned:

he said the "P" word...

I agree with both, I thot my idea over while having a cocktail, and I soon decided it wasnt worth a shit......I am with y'all, I'll do the CO2 setup and forget trying to poison myself with CO2 from the furnace.

Red, and a great idea from you on the secondary monitor, I will add one to my bedroom "just in case". Good insight bro.


Chill the Stoli, and have one on me:rasta:

In your attic isn't there a vent that goes outside?....

No.

If you are pushing the heat outside and you have a SOURCE of cool air.. like the basement or the crawl space under the house... you can use as many bulbs as possible.

I don' t have a basement.

Did you see the attatched image with the floor prints? I'm attatching it to this post also, and adding some pictures I took of the room. I'm not currently living in it, but it's possible to get more photos so let me know.

No way to pull air from down below without drilling holes in the floors or something.

Plus, below the 4k watt flower room is the 1k veg room. Why would I want to pump heat from my veg room into my flower room.

Drawing air from the basement into your grow room and them pushing it into the attic and out a vent is an AWESOME method.. OH YES IT is...

Are you abondoning the sealed growroom idea?

if you watch the trailer at www.seemorebuds.com (i normally don't plug so hard) LOL you will actually see this kind of setup..

Being the "safe" American that I am. I recommend you put your trailer on youtube for a couple of reasons.

1. You can see what websites referred a person to the link and possibly get an IP address.
2. It's better (and cheaper) advertising for you. It gets the word out better. You can probably find people to link to your clips very easily if they are the least bit informative.

Hope you don't take my suggestion as being the typical "arrogant" American.

The pictures above are both of the 3rd floor (4k).

Explain the IP address thing to me?

It is free to have video on google..

I will also put it on youtube..

definitely dont pump heat into your flower room.. I did not look at the floor plan very thoroughly.. my bad..

LOL

Thanks for the great advice then that doesn't apply to my situation. :what:
