Co2 VS air venting

ive done some reading and i am struggling to find much links besides a few words,
basically outside the ppm of the air is 400 and used to be 300ppm of co2, and thousands of years ago used to be 4500ppm, it went down and down till it was almost 0 till we struck the industrial age and it climbed back up to 400, great,,,
California has 400pppm co2 and the sun, giant cobble tree bushes that look insane and require ladders,

in the grow were told in order to handle high intense sunlight light we need to have 600-1200ppm co2, and without it cant handle much light, is this another myth that has been spread from sealed grow rooms? as its sealed you would have to replicate the outdoors more via adding co2,,

in a vented tent were constantly moving the air refreshing the levels of co2 with same as outside air constantly,
unlike a sealed room as they eat it it will decrease and oxygen will saturate, so you spray bursts of co2 high enough to cope with their eating between drops and being that the max before the decline is still higher than the minimum results will show better as the lowest spike after a feed doesn't sink below natures level of co2,400ppm

they say co2 is a waste in a vented room yet many are trying to do it still , im wondering as i use intense lighting and do not supplement co2, but stil grow big plants .. is it a miss communication again like many mixed things i find online like someone does a banging grow co2 sealed the lot and trying to chase him people are like its the co2 get co2 then there all buying co2 and recommending it and blogging before long a trend has started , forgetting that the vents from outside are replacing the same co2 level that nature provided to them who got 4 kilo 20foot trees in the soil ?
or do we need to spend the effort to add co2 ?
big growers years ago never used co2 that i was with some with crazy yields like heath robinson

Well that's a hot mess...

First, you got your physical earth history pretty mangled. More study is in order.

Second, the basic question is about sealed/controlled environment gardening vs ventilated.

Sealed means you get to optimise your grow environment; temperatures, RH, lighting intensity AND CO2 are all important variables. Proper management of these variables allows you to do high intensity agriculture where your plants grow and mature much faster than they would if all of these elements weren't optimised.

When growing in a ventilated space, you have far less freedom to push your plants because you don't have nearly as much control over their environmental conditions. It becomes a matter of doing the best you can with the environment you have. Yields will suffer but you can still have good results.

As you can see, this means that you have a choice.

Yes the CO2/Sealed room shills are lying to everyone to sell more CO2. Can you fucking believe this shit??


NASA is even in on it!!!


lol look up fertilization effect of CO2.

Carbon Dioxide Fertilization Greening Earth, Study Finds - NASA

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon

I think Exhale is playing the long game.

My co2 is vented and hits 1200 at night due to sleeping heads which is my day so i turn up my co2 naturaly and easily in a vented room.
I just have to play my times right that most peeps sleep and booshe co2 is up.

When all is awake i settle at 600ppm vented
If i brew my whiskeys and ferments it rises again to 800 but night can hit 2000 for some reason so i havent been adding any ferments recently .


Read a study tyssik showinga what i said but cant find it about the atmosphere being a con it was on some tnc co2 test by a hydro dude explainging how everuthings a con lol.


I found true when i swapped soil organic and smashed my years of hydro farming witu no fert

I've had a CO2 monitor for years. On summer I set it outside and recorded the high and low for the day. Living in corn country there is quite swing. At night it would rise up to over 700 ppm sometimes but 600ppm was the norm when measured just after dawn, during the day it would drop to under 400ppm usually around 4pm.

But most houses with any amount of breathing bodies will have an elevated CO2 reading Mine is usually around 800ppm with the windows shut. During the winter my CO2 will go up to over 3k ppm sometimes in the house. That's when I take some measures to reduce it.

When the lights are out the plant is putting out CO2, using up store sugars.
