I augment c02 in flower with dozens of different strains of varying maturity full time @ lights on.
Some are first day in the flower room some are ready for harvest yesterday.
If I dont.....my experience suffers. (of course, in my sealed room right)
using C02 is cheaper, easier, less stressful, more precise than exchanging air here, for me and
after my own comparisons since 2009 I know I made the right choice with it.
I have no concerns with stretch, hermies, C0, 02 depletion.

My recipe for minimizing stretch;

Allow vegetative plant to attain sexual maturity before initiating flower
Keep flowering plants as close to the light source as possible without causing harm to it.
Add controls like AC, dehuey, heat, air flow/exchange for full time atmosphere control.
Sometimes stretching is good momma, I often put a plant under the highest light when initiating flower.
This is fun with a mature multi topped vegging bush, when these monsters stretch(I have 11' ceilings!)
they build trees of bud.

Good advice!

I would like to add that potassium deficiency even mild and unseen will cause plants to stretch. Sufficient amounts available promotes strong stocky branching.

I have been dealing with low nitrogen in an indoor organic grow and decided to try it recently.
I go outside to add it to my water. Learned to take a deep breath 1st before opening it then add it and leave the area before exhaling.

i notice you don't mention lighting

does keeping lights more blue-ish help during stretch?

Yes. That’s why some hid users keep the mh in for the first few weeks of flower.

My plants are stretching more since I removed the mh and cmh from my flower room.

Blue light promotes stocky leafy green growth. Red light promotes long growth and flowering.

To much blue in the spectrum can grow very leafy buds too.

I put up a bunch of links about this in the ongoing led vs hps thread yesterday.

I'm a newbie and did buy Exhale bag. I run autos on 24/0 light schedule so I can utilize the co2. Thx

#1 - waste of your money

The gas "bag" is not a controlled release and decrease's after a peak is reached......

You can do better with out those draining your wallet over hyperbole.

Well that’s backwards. The only argument about growth and co2 is that it may not help after about 3-4 weeks in flowering.

Some growers disagree and run to the end but larger plants faster is the way to bigger yield so supplementing in veg is jars as important to final results.

I couldn’t find an excerpt from ed Rosenthals book for free but this page from Grow weed easy has all the correct info.

The only thing missing is the amount of co2 needed for different light intensities but I found earlier when reading 600 w hps can use up to about 750ppm. And no need to supplement below 250 watts. At sunlight levels our plant can use up to 1500ppm. So a bare 1000 watt de hps for example.

As the light intensity goes up temp and co2 levels can also.

http://www.growweedeasy.com/co2

I was wrong earlier about how much light before cannabis can use more co2. I was quoting how much for 1200 to 1500 ppm.

glad you found something. looked for the original article I read a couple years ago with no luck. found a few studies but they were in lux or lumens.... sigh lol. the third I found in the first page said that co2 over 5000 is fatal. stopped reading that one immediately.

maybe
but I just assembled that recipe today. Its never an issue here.

if stretching is an issue for a grower using hps/mh....look at heat, rh, c02, etc and not those lights.
after considering PAR meter results, generator friendliness, longevity I settled on
quantum 485w 220v t5's overhead in veg, many plants growing right into the lights daily
and Ushio 1k hps and mh in flower. I give no consideration anymore to colors of lights other than
observing visible performance and using hps/mh for flowering. I dont ever not once even think about
stretching though. Short new plants are put under the lowest lights and taller ones under the highest lights.
My lights are staged and not adjusted. hope that helps?

I read today that if co2 reaches 1% of the air it is fatal.

But 1500 ppm is .15% normally.

It is all in ed Rosenthals book. Still the best resource for tech info in my opinion. He proved all about light spectrums and uv even back then.

yep I have used both a couple years ago. exhale lasts a long time but puts out very little co2. would need 4 to 6 of them in a 4x4. another product that preys on inexperienced gardeners. the enhance puts out much more co2 you need 2 in a sealed 4x4 to reach optimum levels but it only puts out that much co2 for a week. at 25 bucks for a recharge pack......... tried my own enhance bottle with sugarwater and yeast worked almost as well but after a few weeks decided it was to much work shaking them every day and making replacements every week.

shaking every day? does that make it more active?
I never touch my grog/mash/vino
I had a meter long before a generator in a 2x4x5 tent. 2 gallons brewing raised ppm to 1000 in less than a half hour when the fans were off, so yeah, it works(ish)
I loaned my meter to a friend and we watched mites die in a clear bag @ 6oooppm's, when it reached 10(as high as meter would read) everything top soil bugs were dead and mites and egglings were dead too. yep, that works . its not the c02 that kills them..its the lack of oxygen.
