HELLO CAN ANY ONE TELL ME HOW MUCH MORE YIELD THEY GOT WITH RUNNING CO2 SYSTEM THEN THERE PREVIOUS NON CO2 GROW I HERD THERES LIKE A 25 PERCENT INCREASE ON YIELD USING CO2 SYSTEMS IS THIS CORRECT ???sparkjumper

I ran blockhead for a year before using co2 enrichment and I definately saw a 25-30% increase in my yield.You have to have a real co2 system none of this yeast or dry icw crap and all other factors like lighting,temperature and humidity must be optimum.I use a green air cd-6 propane burner and a cap PPM3 controller.Without a co2 controller any method you use will be unsuccessful,a PPM swing of more than 250-300PPM is death to co2 enrichment,thus the absolute need for a controller.I set mine for 1500 PPM and when it drops to 1450PPM it kicks in my generator.The generator quits at setpoint (1500PPM) but the level normally rises to about 1650PPM even with the generator off,Thus the 200PPM fluctuation for a straight 12 hours and results that are obvious.

i thought so for yield it would be, Im lookin at top end co2 system there not cheap lol propane burner is out of the question so its got to be real mcoy if i purchase one as well i your lookin at what 75.00 a month to refill co2 tank ???

I got a big c02 tank from airgas and it costs 45 bucks to fill...I got a big room and I gotta swap tanks once a week if you don't have a big room it will last much longer...c02 is a awesome luxury and well worth 200 bucks on a regulator...a ppm meter sucks for accuracy on bigger rooms so I just put it on a timerso its off at night (it will burn the crap out of plants if left on in dark)...you don't have to have a crazy set up for c02...as long as you have it in there
) lookin at something like this one I LIKE IT

Why is a cheap lol propane burner out of the question Dr. Fever?Burners serve their purpose much better than co2 tanks,and getting a propane tank filled doesn't bring attention to yourself.Go to a welding shop once a week and see if you dont start getting paranoid as shit.Especially when the guy makes it clear with a wink and a nod that he knows what you're up to.Anyway,you can have the "best" most expensive system in the world and if you don't understand all the other parameters involved you wont be successful.Also hang your burner as high up the wall as you can without burning your ceiling lol and it wont raise temps in the room one iota.Whatever an iota is..And as for filling your "co2 tank" costing 75 dollars a week its more like filling your propane tank for 20 dollars and having it last 3 weeks or so

The word is used in a common English phrase, 'not one iota', meaning 'not the slightest difference', in reference to a phrase in the New Testament: "until heaven and earth pass away, not an iota, not a dot, will pass from the Law" (Mt 5:18).[1]

I have used Co2 for a number of years, my room is 12x10x7 and I use 1 BBQ tank a week. I use CAP controllers and run at 1500ppm. My results have been good, about 150 to 275g more than without Co2 under 1000w, total yield per 1000w is 675. They don't use as much water and ripen about 5 to 9 days early. Resen production looks highter also.

woods it seems our only difference is our room size,mine is 8 by 8.I have 3 1K vertizontals to make the girls happy.To cool an 8 by 8 with 3 1K non-cooled fixtures takes a minimum12,500 BTU window AC,thats what I use.That 50 watts a sq ft is imperative when using co2 enrichment,I also use 1500PPM as my setpoint.I'm between 1450PPM and 1650PPM for 12 glorious hours.Man now I couldnt conceive of flowering without co2 enrichment.It took long enough...For about two years I used my burner and whats called a cyclestat timer.It determines by cu ft of room size the frequency and length of burn.What an expensive hustle!I finally started testing levels with RAE systems co2 kit and man was there some fluctuating going on!Hell I was dropping to 800PPM then rising to 1500 then dropping in just an hour or so.Anyone thats used enrichment effectively knows that more than a 200 or so PPM swing and your plants are not benefitting.They will grow as if the ambient co2 levels were like 350-500PPM.No enrichment there lol

if your light on space and don't want heat, then the burner is not for you. $75 a refill is waaaay too much. maybe you live in the sticks or something. A 50lb tank (the biggest) costs me $42. I recently switched over to a 30 lb aluminum tank. much lighter and the gas is around the same price. My 7 x 7 room at 1300 PPM 18/6 will last about 6 weeks.
I don't run at 1500 which is the commonly referred concentration (no shortage of "oh yeah this is the number" on the forum) as you get a whole lot less bang for the buck above 1300. there is still an increase but not nearly enough to warrant a higher ppm. I run mine off a CAP XGC1 which is the fucking BOMB if you can find one for cheap. It controls light, humidity, temp, hydro and co2 PPM. I would agree that people trying to fubar CO2 are just wasting money. Mixing yeast, just opening the bottle now and then.. running them on a timer. Their is NO effective way to do it besides PPM. Period.
Make sure you keep your temp at 85-90 and your humidity in the 70-80% range when using the co2.Obviously your RH will go down during flower but you might as well have it at optimal when your vegging.
cheers.

I'm sorry to say you are wrong bro,are you an anti-gas extremist lol?Just kidding but I've run into a few that say silly things like "co2 is more for the growers confidence than for the plants.I've heard even funnier shit than that lol.Believe me 12 straight hours of high co2 PPM's in flower without more than a 200-250PPM fluctuation and without any limiting factors such as lack of light or food plus correct temps(85F) and humidity and you will experience the difference for yourself.As for it ripening faster I've never really noticed this but they grow sometimes inches a day during the stretch of early 12/12 photocycle.I've never seen the need to use co2 enrichment in the veg stage

Here's a video that shows what CO2 can do on Cowpea. Somebody posted it here awhile ago.

I am pretty sure the video was made by some pro-global warming nutjobs, but whatever. Doesn't really matter who made it, it's a cool video none the less.

On my next setup i will get a burner and hook it up to the gas line on the house. That is the way to go, no filling nothing! I have a tank in a 10x11x8 and i have to change it ever 4 or 5 days. At $15 bucks a fill, thats about 170 bucks a grow. Really my setup is a bit undersized for my room as it only keeps ppms at about 1300-1400 unless i open the valve more and then I have to change every 2 or 3 days. Either way once you do a grow with it you will never be satisfied again without it.

I use 1 BBQ tank every 7 to 10 days and it cost me 21$ a fill. There is way too much research on the net to not know how and at what to run at so lets not go there. Heat can be an issue with a burner. I have it hot for 2 maybe 3 months a year, I just turn it off. As said above your just better growers... very true but IMHO Co2 is the last thing you do after you have mastered all the other variables, food, heat, humidity, temperature and knowing your plant. If you don't have that don't waste your money. Ask the guys in the hydro shops most say don't waste your time because they know your coming back to say it did not work. It is science and only works if everything is 100%, that's why I use computer controllers and get more yield. The devil is in the details......

thats awesome another question are they hard to set up ???? i mean on controller do u add room dimensions for total ppm to be right ????
