nah i'm sure you're fine without it. my friend that did hydro told me that if you ramp up the co2 you have to ramp up the nutes too... so with a living soil, your plant would eat the amendments faster. so if that was true soil would need to be amended more often. generally, if you're exchanging the air in your room, you have plenty of co2. i've had some great harvest with my 600 watters (a few he didn't believe me until he saw the jars full) and i own a tank and reg, just havent used it. plus with co2 you have to monitor the ppm in the air for it to really be effective.
i've often thought about switching to a sealed room and running CO2 at atmospheric levels though... i'd just have better control over temp and humidity with a sealed room... that's the only reason.

I run it sometimes. Yes you need the regulator. You also need a test kit to set the regulator and a timer. If you have outside air coming in you will be fine without co2. co2 will help if can get the ppms up to 1000 to 1500ppm

@Dr.Pecker
do you find that the co2 makes your plants deplete the soil nutrients faster? i know you're a water only guy... do you run any containers more than once (no till) or do you break up soil after one run and amend it again and reuse for the next?

No not really......I use a Co2 generator (actually a portable hot water unit.....It's the same damn thing inside as a well known and expensive Co2 generator for 1/4 of the price! They are actually made in the SAME factory in China and only have a different cover!)
Break up and re-amend

I re amend the soil. I don't know if it depletes the soil faster, I would assume it does.

i mean i guess i'm not sure how to look at this. I have a decent understanding of the botany of a plant, light dependent reactions, cellular respiration and all that jazz. I guess i don't really understand what is driving the plant to be able to do more crebs cycle to make more sugar simply by just by increasing the CO2 in the atmosphere? I mean i understand that these reactions are happening at unbelievable speeds. is the plant that inefficient at grabbing molecules from atmospheric ppm that when you bump it way up it's grabbing more CO2 which gives the plant more carbon to use? more carbon = more growth. maybe i should do a little reading as to what happens in the plant when CO2 is boosted. you guys don't have to explain it to me if you dont want to lol.

CO2 can be extremely helpful in achieving large bountiful harvests...
BUT.. the drawback is added costs in air conditioning, humidity (added transpiration of water),heat issues, etc.
I did co2 for 5 yrs, and found it really wasn't worth the time and effort, because in order to NEED extra co2 you MUST have the light available, meaning photosynthesis is only as strong as it's weakest link, you have an asston of co2 but if your light isn't strong enough it's pointless, and conversely if the temps are getting too high the plants CANT grow fast enough to use the added co2. To achieve maximum growth you got to add more lights, and in a closed environment, that equals heat.
Sure added co2 can help the plants deal with heat better, but really, if you get a healthy setup with enough ventilation you'll get damn near the same results, unless you REALLY throw some money at it...
Also.... and don't take this the wrong way brother... you MUST have EVERY other aspect of your grow completely dialed in BEFORE, for it to be of use.
I've always had a herb fantasy of an outdoor greenhouse, airtight, natural gas powered air conditioning and the sun providing the light.
THAT is when you'd see some boulders for nugs.
But inside man? it's really not worth it.
And not to mention it could be harmful if not fatal if you grow near where you sleep, if your regulator leaks, you don't wake up.
Adios type of thing. painless death... but you're dead...

ppms need to be around 1000 to 1500 to see any results. like greasemonky said you need more light. Plus a sealed in grow will sweat a lot when the lights are off so you would need a dehumidifier also. With that said I do get a little bigger buds about 15% bigger. My plants use up all the co2 in my grow room in about 2 hours and I don't have fresh air coming in from outside so that's why I supplement. I did have a 20lb tank of gas leak out one night, it was in the basement so no ill effects but it killed all the bugs.

yea, that's my point, if you had your bed down there when that happened you simply don't wake up.
There was an entire village that died mysteriously overnight, and after they investigated they found it was a rupture in the ground, expelling a bunch of CO2. They lived in a valley and the whole valley just filled up.
can't remember where it was, i want to say it was south America somewhere..

IMO one always looks at the benifits of using c02 and neglects safety which should be number 1 priority any person should weight in all factors before jumping the gun kids family pets etc co2 monitors through out house cause remember C02 is a silent killer and pretty sure you would hate to be asked how come your kid or someone in house died to the cops Negligence can still get you life

Yeah I found this right after posting and realized it real quick https://www.rollitup.org/t/tent-grow-with-or-without-co2.505087/#post-7013843
Anyone watch "Death by China"?! Great documentary about the industrialization of China and the Lack thereof in America.
Thomas Jefferson by the time he became president for the second time he says in his Inagural Address that they Abolished ALL Internal Taxes!!!
All offices were paid for through Import Duties and Tariffs.
The Complete opposite today! All these conglomerates get to produce with Slave Labor no regulations Or taxes and then Sell it Freely to Americans without having to pay Import Duties!!!!
Thomas Jefferson said that "If you want to do business with America then you have to Pay" to do business with the most Profitable Nation in the world!
Yeah honestly that's what I read from one guy on the other thread... That co2 Only works If I have everything else Dialed in... It's been a year but I think I'm starting to dial it in...
damn! That sucks!
hahaha yep! As most everything is! I love stuff like that!

temps,VPD etc
The best temps i found when using c02 was 87-89 degrees and explosive growth rates the plants drank 25 gallon every 4 days
And PS was scared shitless when i used c02 inside home where family lived wonderin if you will wake up in morning lol no shit

If you have a healthy living soil it will expel co2 naturally and you can also put your worm bin in your grow room which will also expel co2. Imo this is more in tune with nature rather than pumping a bunch of it into the room. You could also set up a drip system using vinegar and baking soda.

Damn hell yeah brother!!! This is what I like to hear! Definitely going to put my worm bin in there!

get a flock of rabbits in there, and then you can use there bedding and poo too!
Course to get it up to that level of co2... silly wabbits may not be so happy

The idea of a Co2 leak resulting in death is a viable threat!
Toxic levels of Co2 are 50,000 ppm, or 5%.
At 1% your likely to feel drowsy
At 2% Co2 may cause a heavy felling in the chest and you will breath deeper
If exposure to above 2% continues for several hrs. You get acidosis (lowering blood pH) begins.
At 3% your breathing rate doubles and as it nears 5% it quadruples and you begin to die from the toxic properties of Co2 and not from "lack of O2".
Sounds hard to reach but in reality it's not.
A 20lb tank holds 175cf of gas (1 lb of gas = 8.741 cf of gas). SO then, if a 20lb tank leaked from "hook up". You would have a toxic condition in a 3500cf area.
That would be like a 20x20x8 room.....It would also involve 2 1/2 average bedroom size rooms in a home....
Even if you had your grow in the basement....The furnace during the winter months would pull the gas and redistribute it through out the home...
Co2 monitors should always be used and for sure if you run 50lb or larger tanks indoors..
I don't fear Co2. I respect it and take proper precautions. Even though I do not grow in my home.

The theory is that decomposing matter and fungi expel CO2.. And i'm not just talking Sacromyces... If one was to have enough soil that could give off enough co2 to enrich a grow.
However.. we still need to monitor co2, we need to have a system in place prior to enrichment activities. either calculating it with math or a way to monitor an enriched atmosphere. And to adjust temps for anticipated increases in metabolic activity.
As far as nutrients are concerned, I wouldn't change much.. perhaps a tea to favor microbe activity..
