Co2 in my lung room

Co2 in my lung room
So I have a bedroom that is now my lung room it has 4 grow tents and a curing tent, fairly well sealed with exception of r2d2 ac unit exhausting out the window. I’m wondering if burning a couple oil lanterns would increase co2 enough to waste my time purchasing them, don’t want to set up a burner and inconvenient to get co2 tanks filled easily. Any thoughts dgc?

I would be wary of having a flame supplying CO2 in my house but that’s just me. You might be be better off exchanging the air in the room regularly or getting some mushroom bags. And honestly, unless you are running at a really high PPFD you probably don’t even need to supplement.

CO2 levels need to be controlled and consistent during the light cycle. You are not doing your plants any favors with fluctuating CO2 levels during their light cycle.

Is it ok to only use extra co2 during flower? I see it’s important to be consistent. I believe I have everything else dialed in and was thinking of adding a bottle to my flower closet

I only use supplemental CO2 (1100-1200 ppm) in my flower room. I do not supplement CO2 above ambient (400-500 ppm) in my veg room because I want my plants to produce more stomata per leaf in veg. This will help boost growth through the transition to flower when they’re introduced into the flower room’s high CO2 environment. The number of stomata that form on a leaf is determined by the carbon available in the air. Higher carbon levels cause a plant to produce fewer stomata. Low carbon levels will cause the plant to produce more stomata per leaf.

Thank you. Something to play with next run

How many people live in the house? You may be running quite an elevated CO2 already.

Me and 2 dogs

I’m currently looking at these co2 tanks you can fill at home with baking soda and citric acid. Anyone any experience with those?

Buy a tank

I still have great success with self-activated CO₂ bags. I use two different CO₂ meters—one in my lung room and a Pulse Pro inside my grow tent. The cheaper Amazon meter in the lung room measures 1000 PPM CO₂ levels, while the Pulse Pro consistently reads 1400-1800 PPM inside the tent with the bag in use. Without it, my background levels sit around 400–500 PPM, so these bags clearly make a significant difference, and I can measure it.
With the added CO₂, I can increase my light intensity, and the plants are able to utilize it effectively. Each bag lasts about six months for only $40, making it a cost-effective and safe CO₂ supplementation method for home growers—definitely a solid option!
If you live in a climate where you can exhaust your tent directly out a window or outside your home instead of into your lung room for a recirculation effect, you’ll likely experience lower CO₂ levels in your lung room. This can lead to faster CO₂ depletion in your tent since it’s pulling in fresh air with lower CO₂ concentrations. However, even with this setup, you should still be able to maintain at least 800–1,000 PPM inside the tent.

Proof, screenshot of second week of bloom 😎
Sometimes it will spike over 2000 but on average it maintains about 1500 all day long
