I have no idea what this means. Assuming it's an upside down pot plant, how did it fare?
My post I have tried to add 4 times to the above quote on chrome.
I use a study that shows benefits topping out at 1050 ppm. Your paper you posted here shows it before 1200 ppm. yet you want to go 1500 ppm. The guy is carrying co2 and you think it is ok to waste 25-30%. JK
Any of us could do better. He seems to have profited by his incompetence, judging by the title...
Waiting to see how that turns out.
My basic CAP controller cuts on at 900 ppm and cuts off at 1450 ppm. Should average 1175 ppm. 12% above your 1050 ppm. Is that 12% lost or can I maximize it with temp and RH which I can control? If not, tax refund will have to be better controller. Carrying those tanks no joke with bad back. Suerte shifu.
My co2 sensor can only be 6 feet away from my controller my room is 15x20x9 so no matter where I put it some part of the room is never going to get up to 1200 ppm because of the proximity to the generator, so to be sure I have 1200 at a minimum I run higher. Plants that get too much co2 show signs of necrosis on the leaves or stop feeding. I have not run into that. Knowing what signs to look for allows me do use CO2 to my full advantage. Nothing wrong with running Co2 at 700, 900, 1000 or 1200 and anywhere in between, but to say it does not work?
Too much CO2 is bad for the plants. Too high CO2 level lowers plants' transpiration during photosynthesis: without or with less transpiration less nutritive solution is drawn threw the plant, thus less food enters the plant and growth slows down. Under too high CO2 level, necrosis spots (dead tissue) appear on leaves that may also roll into themselves. These dead tissue spots are a great food for bacteria and molds. Too much of a good thing, again, turns out bad results like a lower weighted yield per plant and a lower quality produce.
Well on my second run I have a serious overgrowth issue, dam trees in week 2 and I have been running temps lights on to a max of 93.4 and night of 68.2 and 48% rh, CO2 at 1500ppm, water temp 68 and pH 5.5 and 500 ppm. Plants look great and I'm running Sin City Seeds Nightfire OG, my number 7 cut.
I'll move the rest of the updates to my ongoing thread.
OK so lets say you wasting it, BBQ tank is 25$ here to fill so the 12% waste cost 2.75$ so lets say 1 tank every 10 days, with a 7 week grow = 5 tanks with 12% waste = $13.75 wasted x 6 grows a year = $82.50 a year in wasted gas. All these years using too much CO2 I'm such a dummy, do the math and don't waste your time on low returns to you and your garden.
I don't want to go into teaching everyone about CO2 it's too frustrating with a 1000 word posting limit. Guys were talking about maybe 300 ppm more than most use and people can go on and on but there are so many variables involved, running at 1200 or 1500 with get the job done.
Variables
Plant genetics
Room, sealed or not
Air movement
Air exchange
Time CO2 is on
Time CO2 is off
Open and close the door
Number of plants
Size of plants
Temperature
RH
quality of food
Quantity of food
and more but you should get the idea.
Not questioning your math or motives. Your figures are based on $25 for 20lb bbq tank. You are not factoring in 175lb tanks (which as mentioned way 350lbs min) for $36 that hold nearly 9 times as much. 9 bbq tanks @ $25 equals $225 compared to $36. That is why I lug those heavy %#*&'s. If I didn't have strong brother, as you, I wouldn't even consider monster tanks. Message is, if you have reasonably strong confidant, savings are available with Big Brutus tanks. If not, bbq tanks great alternative. You make good arguments non-sensitively. Enjoy reading your posts. Peace, man.

Holy shit! 93.4 at the canopy??
Yup here they are, these are night shots and most of the cages are 4 feet high.

Well if this doesnt prove high temps aid in CO2 intake then I do not know what does. Granted you have many other factors contributing to their rapid growth but I will be upping my temps today, thanks woodsy!

To me they look kinda droopy. I think you need to dial your temps back some. Walking the fine line one thing, 95*-99*.....you might be pushing it bro. Good luck.
Here's what appears here in Europe about the topic:
These are in Celsius, so it appears that maximum rate of photosynthesis (at 1935 ppm CO2) is achieved at a temperature of 102.2 degrees Fahrenheit (assuming the illuminance is approximately 100,000 lux, which is about what the Sun delivers at most during the day here, on our planet Earth, I guess). I know this might seem absolutely ludicrous, but 1935 ppm CO2 is a lot (drowsiness starts at 10,000 ppm, so it's doesn't seem to be dangerous)!
Good luck!
powda mildew get on it bro it will get out of control quick
