Basement furnace and co2

[Guest]

Hello I have some space in my basement i was thinking about putting a few plants in, the furnace is very close.

I was just wondering, do all furnaces give off co2? Right now its summer so its off, is there anyway to get it to give off co2 when its not heating the house?

Thanks

It depends on a few things. I'm sure some leaks from most models and the older the more I suspect.

It also depends on the negative pressure created by your exhaust. If you remove a lot of air you definitely suck it out of the furnace. I know this first hand. You can smell it.

Since I moved to the interior of BC I'm usually on wood heat so I run electric heat in my shops. I use to see the benefits when my furnace in the city blew back but you have to remember that there can be an element of danger from both carbon monoxide and potentially fire balls.

A friend gets awesome buds when his furnace blows back a large volume of co2 but he also has small explosions inside the furnace system. I laugh because for 3 winters he said he would fix it...he hasn't. It may not be funny at all one day tho....

Almost forgot to answer your other question,

Best not to screw with the furnace. You can go buy a small co2 burner and run it off the gas line to the furnace. It's pretty straight forward. You can just get a tank and regulator type system of course.

You don't *need* additional c02. I'm sure you know that tho.

OK - oil furnaces give of CO, or Carbon Monoxide, you really don't want to be pumping that into your house, because you'll DIE!!!

and the plants will die too......

Mmm, that's right. He never mentioned what kind of furnace....

with oil you'd smell it and shut it down or get the fuk out.
with gas you fall asleep and that's about it.
i lost a good buddy to a faulty furnace and it sucks because it didn't hafta happen.
it's just plain not worth fuckin with mechanical systems for the sake of a few plants.
just my educated opinion.

with a newer gas furnace you would be good to use the co2 put off by it, look at the burners while it's in full heat mode, are the flames a jet blue?? or does it have some yellow? if it's a nice blue flame, like most new, efficient furnaces, you are good to go, if it has yellow in the flame it is burning inefficiently and putting out carbon monoxide as well. a co2 generator is nothing more but a burner burning propane or natural gas, it is actually so simple, as simple as a bbq grill. anyway.. good luck.

How do you go about sealing a growroom airtight anyway? I've never seen a diary on that before. Sheets of plastic lining and duct tape? If so, that sounds impossible for one man to do on his own. How would you seal around the door and still be able to enter? How much difference does C02 really make during flowering in terms of yield, if everything is dialed in properly? Ten percent more yield per sq ft? Twenty?

A "sealed" room isn't hermetically sealed,it's sealed in that there is no ventilation in the room.I use vertizontals with co2 in a sealed room,you want 85 at the canopy with 1500PPM.Two things necessary besides lighting in a sealed room are a window AC if using co2 and a dehumidifier whether using co2 enrichment or not.EDIT Since I've been using co2 correctly with the right equiptment at the right temps and R/O water,the weight of my plants have increased 25-30%.Its the difference between trich covered plants that basically stand straight with little lean,to the same sized plants falling all over themselves from the weight of the buds

I was not planning on manipulating the furnace in any way, I just heard that they give off CO2. I wasn't going to mess with it

I am going to get a Carbon Monoxcide detector now that you guys said all this

 

[Guest]

Is it gas/propane or oil?

 

[Guest]

I dont know its a rental how do I check? The furnace is off as it is summer now

I'd say the easiest way would be to look @ it fuel supply tank...



Oil Burner


or
Propane Burner



Natural Gas Burner

...Hope this helps - Please discourage yourself from messing with the exhaust of any burner!!!!!

A "sealed" room isn't hermetically sealed

Why have I read many times of people taping their rooms up with plastic sheeting when they switch to CO2 enrichment?

it's sealed in that there is no ventilation in the room.

What is the difference between using an extractor fan and AC? Aren't they both ventilation? How is it a sealed room if AC vents to the outside?

Two things necessary besides lighting in a sealed room are a window AC if using co2 and a dehumidifier whether using co2 enrichment or not.

Has anyone heard of water-cooled AC? It uses water as the coolent instead of air, so zero venting to the outside is needed and therefore much less CO2 enrichment would be needed. They also use less power to cool than air cooled AC.

Its a natural gas burner, has to be.

Plastic sheeting is called poly its used to reflect light and keep air from escaping.

Not sure about the CO2 and AC venting it out thing... I would assume you need to put you AC on a timer with your CO2, You're going to have to cool that room down somehow, and maybe just accept the loss in CO2? Not sure heh

Water cooled AC are you talking about an air cooler? It just blows air through water it doesn't cool that much at all, or so I have heard. Maybe your talking about something else I m not sure.

 

[Guest]

Using a window AC recirculates the air in the room,there is no co2 loss according to my controller.A portable will vent your co2 out of the room,even a dual hose.The plastic your probably referring to is black plastic sheeting used over windows to "black out" the room,I used to stuff a towel under my door but I grew up lol

It all depends how cold your water is.

My well water is below 50 and in the mid 30's during the winter. Some city water is 60 or above. It also depends how you use the chiller. I've heard people talk about using water out of a rezzy..recirculate. Well, you are using room temp water then.... Water to waste is the only way to effectively use it.

Here's my chiller I just picked up. I know this worked at my friends 6 bulb op all last summer. Kept his room at 80 no problem and it is only a single fan model. They are a good low pwer alternative solution to temp problems.

 

[fuzygrowth]

only problem with water cooling like that is that if you are on well water, then you will be running you well pump the whole time to feed the chiller, if you are on city water, well, you'll have to pay the water bill.

but yea, who ever was asking, A/C's do not vent to the outside, it recirculates the air in the room or in the system. do a quick google on how a/c's work and you will come up with a bunch of stuff. try www.howstuffworks.com

You can buy some window units with a fresh air option lever,if thats the case just keep it closed.I have this type in my living room to blow fresh cold air down the hallway into my open door vegroom.It doesnt actually blow "fresh" air you know what I mean,the unit provides a small path for ventilation.

 

[Guest]

That water chiller/cooler is a lot more heavy duty than the ones i looked at, i just remembered the name, i was thinking of a swamp cooler

Yeah I have 2 window AC's, dont use em for growing... yet? But one has a option to bring in fresh air from the outside, the other does not have this option.
