Generating CO2 for unsealed room?

Frankly based on my limited research there isn't a chit ton of benefit adding CO2 in any fashion to an unsealed room. I can't say for sure but I'm skeptical a bag of mushroom spore or chunks of Alka seltzer are doing much more then generate money for somebody. Despite the above is think I can increase the CO2 in my unsealed space at no cost but I really need to run it by those with more knowledge than speculation.
The corner of my space is right next to both my water heater and gas furnace. I'm thinking on just poking a 2 inch length of pvc pipe thru the wall at floor level and running a couple T's off it terminating them a safe distance from the flames. Do you think the air in the vicinity of the flames will have more CO2 than the rest of the room. A little comp fan should provide plenty of suckage. Ramble On.

Are you exhausting from the grow room. Just let the exhaust fan pull the air. But Idk, with out testing before and after. Be sure to put screen or over the opening to keep out un wanted guess.

I think your heaters are designed to vent carbon monoxide out the vents to outdoors. So, no, I can't understand why carbon dioxide would be higher near them.

put a chair in front of plants and breath on them?

simple answer yes,will it help?? I run a unvented gas heater in my un sealed room luv it,double the growth rate

moonshine

make your own wine beer or moonshine ........the mash converting the sugars into alch burp prue Co2 ..........depending on the mash mix u can raise your area co2 ppm for 5 to 9 days with the ending result of 1 or 2 gallons of high proof drinkable stuff that u can resale or gift recovering the money spent on the raw materals to make it

works really well but u need to be auto flowers to really get best benny out of it ......24/0 timing as the mash once it goes it goes untill done no stoping it so flowering techinally u could drown the plant in Co2 during off hours

but rum will get u to 1000ppm easy ....done right with a light negitive pressure u can get it to 1500 2000ppm

I have two four inch in line fans. One for intake and one for exhaust. Both have independent speed controls. I haven't even popped any beans yet as I want to be certain I have a nice stable environment first.
I was just figuring that the air closest to the flames of the water heater and furnace would have more CO2 simply because the flame was consuming O2. I could easily tap into to exhaust so it vented thru my space but I don't know how toxic with CO it would be. Maybe I'll combine brewing with growing or better yet I'll just purchase some psilocybin spore and grow my herb along with shrooms and brewing. IDK... Ramble on.

I have used yeast and sugar water. Mixed at a ratio that I can't remember. One gallon at a time, in an old milk jug , I drilled a hole in the top and run some tubbing around the pots cut some slits in the tubbing ,pluged the end of the tub . 800/900 ppm co2

And do you think that helped Mr. Back or was it wasted time and effort. I guess if I'm gonna mix yeast sugar and water I better end up with a drinkable product.

It was a measurable difference , any increase is a benefit .

I'm sure their is a recipe that is useable . I think you could make wine by just adding fruit to the sugar water before adding the yeast .

Bro get a new furnace that beast has seen better days just fyi I have a co2 generator in an unsealed room and it works just fine

I would daddy but the efficiency isn't that much better with a new unit. It's these little taco circulators. I have to change them out every season. the plumber wanted to sell me a Wiessman hot waterfor domestic and heating but I could have bought a brand new truck for the same price. what sort of efficiency percentage do you think I'll gain with a new furnace dadd and do they make one I can also use to generate CO2? Ramble on.

you could always vent the exhaust to where the girls are? even with a new furnace but that would only be effective in winter months what about summer months? Not say venting would be safe either but it would work better yet cough up the 300 and buy a generator is the safest bet IMHO

So, essentially, you want to redirect your heater exhaust into your house? That's smart. Every hear of CO2 poisoning? How are you going to regulate the concentration of CO2?

CO2 is for SEALED rooms, where the concentration levels can be brought up to a set level and maintained with just minor supplementation. CO2 in a vented room is like blowing $$$ out a window.

Not to mention modifying the heaters exhaust, which is part of an engineered system, without knowing what your doing, could hurt is efficiency as well. The flue draw could change, changing your air/fuel ratios in your burner.

I really don't get why so many people don't understand such a simple concept.

Running co2 in the 4x4 tent I used to run unsealed got me 3 more oz of bud, not really wasted money in my opinion. But it was only under enough negative air to get rid of the smell, and vented into the same room it exhausted too so it was really wasted.

What simple concept am I missing weed freak? I'm not really concerned with the CO2 levels but I would be concerned with the levels of CO. im really not going to tap the furnace exhaust but if it gets cold I'm gonna start a charcoal fire. NOT REALLY.
I WAS going to pipe the air from as close to the flames of the water heater and furnace as possible. I was just speculating that the air closest to the flames would contain more CO2 than the air in the rest of the room simply because the flame was using up a lot of the O2 in the air leaving CO2 rich air behind. I guess I should find out how a flame driven CO2 producing generator works that allows it to produce CO2 W/O producing CO. I do have an unsealed room but there is no reason why I couldn't stop the air exchange to give me a chance to augment the CO2 levels for an hour or so a few times a day. Thanks for the heads up though weed freak. Chit... this house has more smoke and CO detectors than needed. I'm just grateful for the radon gas detector. You never know about that radon. Ramble on. Can someone point me in the right direction on CO2 generators? the benefits seem tangible.

Start a worm bin. A small herd of 10,000 worms and bedding should produce a bit of CO2 + worm-castings.

HA, got me on the CO/CO2! I always do that. We're neighbors, I'm from Mass as well, Hi!

Simple concept is CO2 is for sealed rooms. I don't have first hand knowledge, but I've looked into it enough to figure that out. If someone can't show quantifiable results in a somewhat controlled(clones in same medium, same lights, nutes, etc) side by side of a CO2 vented area and non CO2 vented area, take any claims with a grain of salt. I never saw any. I've wanted CO2 for awhile, but can't afford the AC to cool my room if I sealed it. I thought about what you're talking about. I was going to use a CO2 controller to operate a damper I'd install in my heaters exhaust ( at the flame or up the exhaust, is all the same gases) to redirect it to my room. After researching it, I decided not to for reasons I listed.

I assume LP/GAS CO2 generators still produce CO, but in a sealed room, CO2 levels are brought up to ~1500ppm, the burner shuts off and doesn't reignite until levels drop, so there's a limited burn time. In a vented room, it will continuously fire, and be vented out into your house. I suppose you could vent directly outside from your area, but you would have to allow make up air to enter the house, or room directly, from outside. Depending on how well your house is sealed, venting outside without make up air, could potentially cause a negative pressure in the whole house and start drawing exhaust gas from the heater back into the house, so that gets complicated.

Haha weed freak. I should have figured you were another masshole. Both my intake and exhaust go straight to the great outdoors. My concern right now is how much air I am going to be able to bring into the room when the Temps really drop. I may pull in some warm air from around the water heater and furnace just to offset the chill. WTH, IDK but I should be able to juggle things around so I can maintain a good average temperature and humidity level. I'm ready to pop some beans but I want to let things run for a week or so just to iron out the kinks. Ramble On

co2 is heavier than air,your basement is a hole,u cant pull cold air into warm room I live in maine believe me if out side freezing it will turn to water hitting warm room run a small burner with very little venting,
