Co2 Bag = Higher Temps?

[Nartak]

Hey GWE,starting in a couple days im gonna germ 4 seeds in a small plastic germination box with rockwool cubes.I bought a co2 exhale bag and wanted to find out first of all,does co2 enrichment enable higher temps for germ/seedling stage(up to 2nd week of life) or is it helpful only after trueleaves pop?

Also ive read over the temp guides on the forum but i would like a more personal view,what temps do you/would you have in a 4x4 + 600w MH + CO2 ?

Green75 uses co2.

It would make sense that higher temps due to co2 would span all stages. I'll defer to the experts though

[Green75]

I use co2 from time of sprout all the way till last two or three weeks of flower....

Co2 definitely let's the plants be able to endure the high temps. My tent was rockin 90°' for awhile this summer and plants were kickin ass.

The growth with Co2 is amazing...

What is a Co2 exhale bag..?

[Nartak]

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..

What is a Co2 exhale bag..?

Exactly. I just use a ball jar.

[Green75]

For what...

[Nartak]

I bought mine from a hydro shop online but this is the company i got (not many choices where im from)

Bicarbonate of soda and distilled vinegar.

[Green75]

Tell me more please...whole thing

[South Sierra Dude]

Look at the middle of the floor. See the ball jar? I just keep it bubbling all the time.

[Green75]

If that is how you are getting Co2 ....make it a bucket and hang from ceiling...Co2 is heavier than air and needs to fall...

[Nartak]

That is cool!How does cover the foliage though? Do the fumes help it go up?(As green said,co2 is heavier that air)

[South Sierra Dude]

I have fans; also note that denser gases only behave the way you described when they are in a balloon or similar object. In the open environment they dissipate until even distribution is achieved.

[Green75]

Not on the floor blowing up you don't...

As is it's a waste of time....

Good ideal tho...need to be a bigger scale

[South Sierra Dude]

See edit above.

[Green75]

Sorry man... You are wrong on this one bro...do some more research man

Not looking to argue....peace

[South Sierra Dude]

[Green75]

I'm sorry....still not buying it....way to much info out there that disputes that....Co2 is heavier plain and simple....read how to apply Co2 with weed grow....

Plus that little ass jar and exhaust fan....it's a waste

[South Sierra Dude]

Just re-researched it and it turns out it's called Graham's Law. Graham's Law is a relation which states that the rate of the effusion of a gas is inversely proportional to the square root of its density or molecular mass.

Rate1 / Rate2 = (M2 / M1)^1/2

The jar thing works, look at my plants.

[Green75]

Plants look healthy...all good man keep banging away

[South Sierra Dude]

Now I won't be able to sleep at night until I get a co2 meter.

[Green75]

I hope it is working for you I do....but there is no way...if it was that easy.....THE WHOLE WORLD WOULD BE DOING IT...

DAMN I DO WISH You're CORRECT......

[South Sierra Dude]

Still working the calculus on that.

[jalbertson]

It makes perfect sense. He said he has fans. Even in a closed environment with a fan, the Co2 wouldn't settle lower than the air, theres another factor affecting the gases. The weight or density of the Co2 couldn't be overpowering the fan. How could the Co2 settle when the fan is physically stirring up the gases?

[jalbertson]

Don't think about the chemistry, think about the physics.

[South Sierra Dude]

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.
