Yes i also saw the co2 buckets …i definitely will be getting at least the diy one setup asap… this is literally my 1st real attempt at growing and would love to optimize what i can! Love the input thanks yall

See the issue with supplemental C02, and anyone that uses it in a pro setup will agree, is that for it to be of any benefit your system needs to be closed. You cannot effectively use CO2 enrichment and ventilate. It defeats the point of doing it. The idea is to enrich not deplete C02. I wont go into details… perhaps someone on here that cranks the watts and has a proper Co2 show can elaborate with more detail. What I can say for sure is… if you do it right you can double plant growth over standard atmosphere. Again… its a big expense to do it properly, and you will need gas in bottles with guages and proper valves. You will need sensors and a proper ventilation system to do this. Its serious level stuff here boys and girls.

Oh and very few growers, even really high end growers, do it. To expensive and if you arent all in… there is very little benefit.

@Cannabian that makes sense as well…which is why i found the stakes that go around the stem into the ground intriguing because it seemed to direct inject it to the roots…idk if i am right or not

Uh nope! C02 is taken through the leaf and exchanged in the root zone. Plants breath C02 and exhale 02.

@Cannabian ,your absolutely right, with EVERYTHING YOU SAID, but it’s in no way BAD to put a $50 pro CO2 bucket in your tent if you can afford it, I could and I’ll do it again!! And will say that even though some of it is pulling out through my ventilation, the co2 that has remained, has been VERY beneficial to my ladies!!!

right…maybe it just stakes in the ground and releases it up idk…just thoughts
Like I said @JamJam a LOT if back and forth, and a matter of preference and several other factors

If I don’t use the sugar and yeast set up my CO2 drops to around 400ppm.
With the jug in use I’m able to maintain 800-1000ppm.
It might not do much but I feel better running it in the background.
I DO however understand how dangerous it can be because with a fresh jug I can
watch my CO2 levels climb to 1700-2000ppm without the fan running. Just being able to
maintain a decent level for the plants to feed on makes me sleep better at night. Call it
the placebo effect.
Also, I’m on the 3rd floor so since CO2 is heavier than oxygen it’s tough to keep those
levels up.

Mine is at a constant 1000 to 1200

If I give the bucket a shake it’ll jump to 1500 for about a half hour, than drop back to roughly 1100

When the lights come on my AutoPiolet reads 1300-1700. Within an hour or two it’s
down to 1000-1200. By the time the lights go off I’m reading 800-1000ppm. So it’s
like a balancing act that I don’t participate in.

Right… all good points folks… remember that when you look at cost inputs versus gains it doesnt make sense ti run C02 unless you use a closed system and push big power in lighting. Even still, if I had the choice and the facilities and the money, I still would prefer to run anstandard ventilated atmosphere and spend the money and time improving environmental and growing skills. This is where you really see the results.
It takes me back to the main reason a clone is so useful, because you learn what a plant likes over time. By the time veg is over, most if us are just figuring out what that plant likes. You now have a second or tgird chance to improve on the technique. You know, I didnt just grow big plants… I had to learn how over time. Several f…k ups later I now know hie to get 2 pounds off a plant.

@Cannabian NICE…that would be sick to get 2lbs off one plant. Hopefully i will one day

Run an A/b comparison in a fair manner. Use your C02 delivery system vs a non system. Use clones for accuracy sake. Same lighting same food etc. You will then see that technique has more to do with quality than CO2. Most of the top growers here have produced killer dope without it. Talk to @Hoppiefrog about growing his 100 bucks a seed killer weed ? Can he do it with a normal atmosphere? Hell yeah he can!

Ive grown plants that Ive pulled 9 pounds off! Thats 1 plant! This plant probably has 12 or more pounds on it?
no CO2 supplements here I guarantee that!
I use this image to demonstrate cannabis’s potential. It can be quite spectacular… while ive grown some big dope over the years, this is just fricken awesome! Not mine.
Looms lime a Macintosh apple tree dammit fricken massive!

I’m far too broke to attempt to pull off any side by side comparisons. My apartment is 550sq ft.
If I actually had the money to do it, I’d have to sleep in my car due to lacking space.
However, showering and brushing my teeth in a gas station bathroom might be interesting.

Well if dough is that tight, CO2 is a definite f…k nope! Dont waste another dime trying to create it. Any half decent grower can do excellent without it.
CO2 brings extra speedy growth but nothing else really changes as far as quality other than making plants able to handle higher levels of light/food/temps and therefore humidity/vpd

@Cannabian is absolutely right, you do need a dialed in system, a sealed room/area and ontop of you gotta do a bit of math
So co2 is heavier than air so it creates a rain effect.
Issue is this enrichment can be carried away by our exhaust…so what we do is
Find the cubic area of the room, time the frequency of the ventilation, set our regulators to be able to fill the room to appropriate level in the intervals we then need
So by putting a bag in your grow with vents running your blowing most your product out the window
Also, I have co2 setup, I have it regulated to be able to fill the 960 cubics with 400ppf of enrichment meant in a 10 min window between my cycles of exhaust.
Im not going to use co2 for this grow
Why? I just started using the area, I want to actually push a grow cycle or three through the area to know what it’s producing alone.
Then I’ll enrich the area and see if I can keep up with what the plants need
