Seems to me the amounts of CO2 transported to the plants from spraying seltzer water would probably be quite small and sporadic.
And do the leaves absorb CO2 in that manner? Another problem is that preferably when applying CO2 you want maximum lights going and even quite high heat, risking burns.
Is it worth the effort?'
.
No. IMO, it is NOT worth the effort/risk.
If you want to add CO2, do it through the air. Do it the right way. Sealed up room, decently high temps, no exhaust. I think spraying it does just what you said, adds very little CO2 (probably some, but not much) and does risk burning your plants (trust me on that one...)

For the most part I do agree. Also, I think that CO2 came up on another thread that you were on and the question was "When to use CO2" and if I remember right you said that CO2 is used by the plant all threw the grow and I had stated that CO2 is best used in flower. You are right, the plant can always use CO2 in veg and flower, but for the most part, with CO2 methods being expensive and so on, I feel that in most peoples opinions, CO2 is used in flower more because the level of photo synthesis taking place is directly related to bud development and the CO2 can proportionately have a greater affect at this point, and also, when the plants are in veg and smaller the amount of Photo synthesis is proportionally less and the CO2 is questionably having even half of the affect that it does when in flower.
But you will find growers that don't even want to run CO2 in flower for fear of losing potency, but this is a small amount of growers IMO.
Sorry to high jack the thread, but I guess it is still on the topic of CO2 and I hope that it helps either way.
Adieu
Absolutely, Bluebear. That sounds about right on. Do have to say that I didn't know anything about using CO2 and losing potency, though. :confused:

It is debatable Fog, but even those who say that, still admit that the yields are greater with it and it is a small trade off, but like I said, this is a small amount of growers that even subscribe to the theory of not using durring flower.
Adieu
i think C02 can help, but like said its tricky and probably expensive to get right...
for the average grower, i think money and effort is probably better spent on other aspects, like nute ratios, soil mix etc.
with good ventilation, theres 'enough' c02 in the air, adding c02 is benificial up to a point, but IMO not worth the efort unless the other more controlable variables are tweaked to max potential
I do agree, you do want to have your grow dialed in with every thing else before the CO2, IMO. You know growing has different levels and it is a learning experience and you learn by going threw all of the steps rather than by skipping them.
Kind of like a new carpenter or mechanic, why go out and by $5000 in tools if you only no how to change the oil and air filter, or change a door knob and put up some trim.
Adieu
In my opinion a little co2 does the world of good through both grow and flower stages.The cheapest way i found to produce a small amount of co2 in the air was to stick my home brew kit in the grow room.....sorted.BTW anyone tried making beer from the clippings ??
Now a DIY CO2 source is a good way to start off because it is just allot cheaper and will give you a chance to see if it is what you want without spending 800 bucks on a CO2 controller and another $200 to $300 on a tank, not to mention the other costly modifications that sometimes need to be made to really get the altimet benefit from the CO2.
Adieu
im all for that, i would certainly do the same if i was brewing beer.
in that way, its a free and usefull biproduct.
.
I've got a 1½ litre coke bottle brewing yeast and sugar all the time, but I'm a little doubtful it's doing much.
.
Is the CO2 from the bottle coming in from the top of the area? Do you stop your fans off and on throughout the light period? I guess even with the little DIY's there is a bit of work to get some bennifet.
Adieu
Ive used moderate controlled amounts of CO2 (from a tank) for a while and found it benificial, but if your growin less than 6 plants i wouldn`t bother.
The home brus not a bad (relativly cheap) way of gettin a bit more in there, and you get a load of bear to go with ya bud, but be carefull your humidity doen`t go though the roof with all that booze in there.
But spraying i wouldn`t bother, i`ve heard a lot of people think about it even try it but i have only seen BAD results, and personally i would never spray anything on a buddin plant unless i had to.
Try to perfect every thing else before you spend out on a CO2 kit.
Just my three bits worth.
Ok, well I've never heard that. Would like to try using it though.Quote:

I have a thin pvc tube like a straw inserted and insulated near the top of the bottle, that stretches out a little bit above the plants. There are a couple of small 3mm punctures along the way above the plants.Quote:

for starters the home brew is absolutley worthless, the amounts of co2 are not consistant enough, let alone high enough to make a difference, please dont waste your time
your grow must also be very stable to utilize co2, if your plants arent getting enough aeration, light, properly balanced nutes, and stable temps/ humidity, they wont be at peak photosynthesis to utilize supplimental co2
you also need to factor in how many people live at your house, most average family homes are at 600-1000 ppms, compared to the outside which can range from 300-600ppm's depending on location
also co2 isnt really that expensive, the average kit and 20lb bottle will run you 300, in my 4x4 room it last 2 weeks with it set at 1000ppm and its about $18 to refill it
the last thing i wanted to comment on is how to properly use co2, whatever ppm you plan on supplimenting it at keep it consistent to that #, ive read a few places where people shut off there fans and enrich co2 for a short period of time and then turn there fans back on, plants dont use co2 in burst, they use co2 as they need it, your going to get more results with a small amount enriched over the entire length of the photoperiod, compared to spiking the amount high and letting it drop, your plants will adapt to the amount of co2 in your room and structure there metabolism around that specific amount, thus why i stress a stable enviroment
in the end im a supporter of co2 enrichment, ive experienced nothing but good things, definatley higher yeilds, but the rate of growth is why i keep on using it, ive easily cut 1-2 weeks off my flower time by supplimenting co2 at 1000ppm

Interesting Caliorbust. I'm thinking that beer tanks in bars are often driven by 30l CO2 tubes that cost about 60-70 USD, at least in my country.
Any reason people don't use those?
.
So misting with carbonated soda is out of the question when the lights shut off?
Carbonated water I meant...........

Heh. Oh well, his price estimate seemed so expensive is what threw me off.
