Stealing co2 for my veg

I currently have a NG powered tankless water heater providing CO2 perfectly and cheaply to my flower room. On the other side of my basement is my veg, and I wanted to leech some CO2 over there. I'm not too concerned about inefficiency because my heater creates CO2 really fast, and NG is cheap, just curious if anyone has done anything similar and how they did it.

I was thinking of something along the lines of 4" pvc or duct with just an in-line booster fan either constantly on, or on a timer from my flower room to my veg. I wouldnt pony up the dough on a seperate CO2 regulator/controller at least not at first, and kinda guess at it. Also my veg fan is always running with a filter, but smells aren't too much of an issue there. I could put that on a temp regulator or alternating relay of some sort with the booster fan. If you've never done this, what are you opinions on this idea?

co2 is very important during veg. Ever notice how come all plant species were gigantic back during Jurassic period, because co2 levels were ridiculously high compared to today.

If you are using an AC and DEHUMIDIFIER to control each room then you could just Exhaust each room into the other. This would work best with a sealed air cooled lighting rig in each of the rooms with its own cool air intake and exhaust away. Run AC's to keep temps in check along with the dehumidifier and have a free standing fan and filter combo setup in each room if needed. Then exhaust flower room into veg and veg room into flower. Thus creating a loop of air that is replenished by your tankless NG heater.

I'm confused, and know nothing about tankless water heaters.....don't they just have a heat source that heats up small amounts of water as it passes through, thus not needing a big tank of un-used hot water?

If this is right, than an open flame would create CO, and not CO2, correct? Am I missing something here? A propane or natural gas CO2 burner converts the CO into CO2 does it not?

I use bottled gas, so I have an excuse if I'm wrong, which I really really hope I am!

propane creates CO2 if burned properly & completely. otherwise it will create some CO. as long as you have a small blue flame,you should be good.

Thanks! I was kinda freakin' out for a minute....my friends daughter died on her 12th bday with her stepdad from co poisoning. That shit freaks me out.

pretty sure you'll have a co problem. You may die from it. Buy a co alarm. co and co2 are only 1 molecule off.

Greenhouse plants photosynthesis needs higher levels of carbon dioxide due to higher heat. A greenhouse plant uses more Co2 than non greenhouse plants. Plants require carbon dioxide to conduct photosynthesis. A greenhouse may enrich their atmospheres with additional carbon dioxide keep the photosynthesis process on going . With the earths atmosphere at about 395ppm of Co2 a greenhouse needs to raises Co2 levels to around 1200-1500 ppm with air circulation, because the plants will deplete any carbon dioxide in the air around it instanly ,by circulating the air it replenishes the supply of Co2 constantly throught the light cycle to keep photosynthesis at an active state........... thus stonerman has it right with the jurassic period

Theres a couple real good threads on Hot water heater CO2 supplimenting. This is the basement of mine and my wife's house so I did weeks of research and still take extra safety precaution. I actually put a CO detector by the tank exhause, and another one in our bedroom just for paranoid good measure. I can see the flame, it looks good. I don't want to turn this into a Water cooled CO2 thread, but seriously, ive seen burner setups, and tank setups, and nothing comes even close in regards to price/performance. I have natural gas rather than propane which reduces costs by about another $75. I think the people who aren't using it yet, either don't have the capability, or just don't know about it yet. Popularity is going up, and I think it will eventually become the standard. I was actually going to convert my hardwired smoke detectors to CO combos, but the technology just isnt ready. They have a huge amount of false alarms, and bringing the fire department/cops around is not a good option for me unless I'm really confident theres a deadly emergency.

But back to my original issue: My veg currently isn't climate controlled, though I put a space heater if it gets too cold. Right now its a 6'x4' with 1k watts, 24" filter, 8" 750cfm fan, though im gonna probably expand the footprint, and add another light. Since I'm not doing AC at the moment, I'm afraid recirculating between the 2 rooms will raise my temps too much. I was hoping someone had done something like this before and could shed some light. I have friends that use a seperate CO2 tank system for their veg, and they swear by the results. Faster bulking in veg is very helpful to my setup/schedule. Otherwise I'd save on the electric and veg with t5s.
