Does co2 make your buds denser?

CO2 gets an impression that's better than it actually works, IMHO.
I have run sealed with bottled CO2, I've used a CO2 burner with a little more open grow. One thing to remember is that it's only for lights-on, and ripping some fans to cool the lights will just spit the CO2 out of the grow room. To take full advantage, it really needs to be a sealed grow with AC, or you're just wasting the CO2 (and money). I've also NOT experienced the temp benefits that some claim. I've seen claims that you can run at 84+ degrees all the time if you have CO2. I disagree. When I got into the low 80's at lights-on, the results were fairly poor. Drop that to 75-ish and the plants are much happier and denser.
There really isn't even an agreement on how much CO2 to run. I've seen anywhere from 900 to 2000 ppm suggested, and I've run 1100 and 1400pppm lights on without noticeable differences. The CO2 equipment is expensive. The meter/controller/regulator is going to cost you about $300 for bottled CO2, then the bottles are about $100 each, plus $10-$15 each fill. So, you'd need about $500+ cash to even touch supplemental CO2.

Important thing to note is that co2 works its best when all the other variables are in place. Some genetics do not tolerate higher temps, others thrive in it.
If your nutrient levels are adequate but not dialed in, co2 supplementation will not make up for that.
If you have your temps figured out and you're feeding just right, co2 takes it to the next level.

Thanks for the replies. I have ran co2 before with 20 and 50 lb bottles but i cant say that it made my buds denser than when i used a vented room. I did boost up the feeding but had temps in the 80s. I havent seen anyone say anything about density with co2, just the usual weight increase bigger buds flowering times and what not.

Honestly, it's just such a pain in the ass to deal with. Your entire setup needs to be built around the idea of sealed rooms with CO2 and AC. Even if someone could prove that it's going to give me another 10%-15%, I still would chose not to run it (again).

Same here it was a pita to carry the bottles to and from the grow and the smell leaked everytime door opened. Im thinking about giving it another try if the buds do come out denser from the co2. Anyways what do you know about the moon cakes with the ball in the middle
extend your co2 solenoid leads and pipe
extend your co2 solenoid leads and pipe
I extended my C02 solenoid lead and ran 3/8 th copper pipe to room from the bottle
mainly because i had 180 lb bottles they stood downstairs in my work shop.
The other thing thats relevent i run ebb/flow in hydroton and C02 is drawn down into the root area.
Definatley darker and close internodal spacing and density.

It really depends on how sealed it is and how LARGE the grow is. I've seen 5-gal propane tanks lasting less than a week in areas with 10 or so lights.

Does too much DIY co2 (yeast, sugar, h2o) in my dwc causing brownish sljme accumulating on hose and roots, seedling, 5.8ph 600ppm at 72f, in enclosed tent, 300 LED 80s ambient
