Co2 Bag = Higher Temps?

It does say a fan can blow it around...I just wanna know if you read it.

Answer me this....why aren't more people doing it

Why every pot article or book say to have it above them
 
A) it was a thousand pages long, talking about random stuff, B) then why are you arguing, C) I don't know why people do the things they do, their idiots.
 
I read it..says for their theories to work need air tight room/container....and each one had different temp raise or stay the same to work as well....like you said...who's tent is air tight?
 
Hey Green,glad to have a greenthumb on the matter!!A co2 exhale bag is a bag with a vapor seal that contains mycelium (mushrooms fungus) and you just hang it above the plants for aprox 6 months..
 
That is cool!How does cover the foliage though? Do the fumes help it go up?(As green said,co2 is heavier that air)
 
My bought "exhale" bag gives out 1139ppm right at the vapor seal it has for output,having it between lamp and floor the ppm above the bag at the top of tent was 1138 (11cm distance from bag) and bottom was 1139 again...will try swapping the distances around today!
 
Anyhow Green75 what temps do you "keep" from sprout to crop? i was thinking about my HPS problem where at 2 hours of working with my exhaust fan (no water in wilma tank,no dry fans on yet and ofc no plants) it hits 30 celcius and a good drop to 40% humidity! I know i can get a wet towel in there for humidity but i can't install another intake/exhaust fan right now so i'll have to use the co2!
The temp will surely be lower at the pots (40cm above floor) so prolly about 28-30ceclius id say once the whole op is functional..
With the mention ppm (above 1k) will (Lights on : 26-30) (Lights Off : 18-24) be ok? Im doing 4 Church from seed if it plays a general role,but im trying to find an average of somewhat...
 
If by blowing the co2 you diffuse it faster. Cause it to disperse or diffuse quicker. You still can't shoot it up. Wouldn't the co2 be equal 20k up and also at sea level if the co2 was being blown and mixed by our own wind and wind tunnels and air flow. Co2 would be the same at our highest and lowest atmospheric points but it's not. Probably because it's at a constant state or place where it's diffusing and mixing

Is there co2 above my canopy RIGHT NOW? Yes. But you my friend are dropping gas right on top of your canopy allowing it to fall onto and disperse. Where as lower additional co2 yes it's there and yes it's additional and yes it moves. But does it rise? Or does it sort of diffuse / combust/ mix within itself

I'm going with the manufacturer aka science on this one.
 
I am convinced ....I said that for argument sake...

Let's see a picture of your garden...with all this indisputable information you have it has to be awesome probly way better than mine....huh
 
It's a law in chemistry as well as physics. They don't disagree on this point. Look up Gram's Law. It is not Gram's works this way some of the time.
 
My understanding is:

Average expected CO2 ppm is about 400.

Desired CO2 ppm for maximum growth and yield is about 1500.

If you have a ppm of 1138-9 top and bottom of the tent as described below then I'd say that CO2 bag is doing a much better job than I've ever experienced. Out of curiosity, what are you using to measure the CO2 PPM?

There are a few things that are worth bearing in mind though:
  • Usually CO2 is used to increase yields and maximize the output of a high watt lamp. If for example you have more light than your plants can normally absorb then increasing the CO2 will help the plants make use of the excess PAR.
  • If your tent isn't sealed then the exhaust fan will be removing the CO2 from the tent causing you to waste the additional CO2. You could turn the extractor fan off or down to a lower RPM during the lights-on period to allow the ppm to increase above 1200ppm, however that will likely raise temperatures and humidity so keep an eye on those metrics if you do.
  • Whilst CO2 will raise the temperature threshold of the plants so that growth rates and yields are unaffected (or likely improved) by the higher temps you may still be evaporating off some of the terpenes if you go above 95f, so again keep an eye on those metrics.
It's worth having a read of the CO2 grow guide it highlights most of what I've said here and does a much better job of explaining it.
 
Im using co2meter.com's small humidity/temp/ppm meter,thanks for the pointing to the guide ;)

I know i have to maintain a 4digit number of co2 ppm but i can't seal the tent as i will then face 35+C so i will keep my 400lt/hour exhaust fan on all the time when in veg and will be switching it off at lights-off in flower stage to keep the air clean,the heat down and the co2 as high as possible...
