alternative methods to add CO2....

just wondering if anyone out there knows of any other ways to add CO2 to the grow room, i've heard of yeast but dont know too much about that... ive also heard that misting your plants with carbonated water does wonders, anyone have any experience with this??? and i myself have added carbonated water directly to my soil, but that was on my first grow so diddnt have much to compare to, i got an oz from each plant, 4 plants total under 250 w hps, i know this was quite good for a first time but maybe i just got lucky, so anyone got any other forms of alternative CO2??? thanks.

Your really not in the position to use c02, you need to push the plants to their very limit as far as lighting and nutrients, until you do that its like giving steroids to Jared Foggle. You have to max out the system first before you try to raise the ceiling.

Remember, supplemental C02 simply increases the amount of light and nutrients that the plant can process.

and i myself have added carbonated water directly to my soil
not hating on u, but y would u put carbonated water directly into ur soil.
roots need oxygen not Co2. Co2 is for the leaves n flowers n stuff. i dont know, i kould b wrong. peace.:leaf:

i read a thread on it here a while back, diddnt think it could do any harm and it did not. your probably right though,

CO2 will kill yer roots, roots use oxygen NOT co2. The foliage ( Leaves) use the CO2. there are basically 3 ways to do it. get a CO2 generator, use yeast and sugar water ( Nasty smell), or go with the tried and true 20 or 40 pound bottle with a regulator. The regulator is expensive, but if you do it wrong and get too much CO2 the plants will die, if not enough CO2, they won't grow as fast as they could. You want 1500-1600 PPM of CO2 in your grow room.

Generators use propane/nat gas to burn and the CO2 is a byproduct of the burning. creates alot of heat.

Yeast/sugar water..you might need a couple of containers of the solution to get the PPM levels high enough, you will need to add more sugar and water to the mix everyday to keep the CO2 going.

20/40 LB bottle..cheap, easy, no heat, easy to get refilled, cheap to rent. regulator cost is a bit much ($120), but you cannot use the bottle without it.


There are other methods ( Dry ice, )) but they are either too hard to accomplish, or too expensive ( Dry ice =$50 a day.

Hope this helps

I would not waste your time or money if you areusing a 250w hps.. If you get a 400w or 100w hps then I'd get a tank and regulator Like NoDrama said its the best way to go...

You guys talk about "it dosnt hurt" when you have no idea, certainly no reason why spraying soda water anywhere would hurt. a .2 mil increase in co2 will not be as effective as raising it to 2000ppm for 6 hrs a day with recirculating climate control.

When I said not to use co2 i didn't say light was the problem, I meant you, not advanced enough to be tricking out your growroom this way. You can get WAY bigger improvements if you focus on other more common limiters of bud growth.

Spraying the soda water hurts as much as spraying regular water. It leaves the little droplets behind that act like a magnifying glass causing little burns. Now you can spray at night when the lights are off (when you are supposed to mist them), but plants don't use co2 at night.

Plus misting flowers encourages mold growth.

I agree. CO2 is the last thing to add. Its not cheap, and unless everything else is spot on, its much less effective. (read: little bang for the buck)

Its kinda like learning to drive at the Indy 500. (bad analogy, but best I could come up with quickly)

I whole heartedly agree, but come on, the Jared on steroids is perfect.

And CO2 is USEFUL with the lights out?
Foliar feeding instructions:

You can use any full spectrum nutrient to foliar feed your plants. To avoid nutrient burn, your nutrient solution strength, should be no more than 1/3rd of the maunufactures reccomended dosage.

* The best temperature is about 72 degrees (when stomata on the underside of the leaves are open); at over 80, they may not be open at all. So, find the cooler part of the day if it is hot and the warmer part of the day if it is cold out.

* Use a good quality sprayer -- should atomise the solution to a very fine mist.

* Always be sure your light is off and cool before foliar feeding! For extra safety, wipe your bulb with a dry cloth after spraying and make sure H.I.D lights are raised to a safe distance (double the distance is a good rule of thumb) to prevent burning.

* Make sure the PH of your solution is between 7 and 6.2.

* To prevent the water from beading up (acting as small prisms) and thereby burning the leaves, for each gallon made, add half of a teaspoon of liquid detergent (wetting agent).

* Spray leaf surface -- the tops and the undersides -- until the liquid begins to drip off the leaves. Stop spraying 2 weeks into flowering -- use sparingly on bud sites.

* Dispose of excess spray according to manufactures instructions— home made fertilizer sprays will be fine for at least 2 weeks.

* Spray one time a week every week, if any white residue is found, rinse the foliage with plain ph'd water to reduce salt build-up.

I was thinking of dry ice for a bit of increased CO2 until next time around when a proper system should be affordable. I just don't see the $50 a day? unless you are looking @ prices of ordering online where you might spend a ton on special shipping.

In my area dry ice can be purchased @ the local grocery for .99 cents a pound. I would think 1 or 2 pounds of dry ice (dry ice = pure CO2 so 1 lb. dry ice = 1 pound of CO2 gas) evaporating slowly ina cooler would be enuf CO2 to be beneficial & make it worthwhile in a small room. Until of course a proper system can be afforded. It may not make 1500+ppm but I would think it would ammount to noticable results & do better than the yeast method. But I haven't tried it yet so i could be off. Does anyone know how long a 1 lb. chunk of dry ice stored in a styrofoam cooler w/ just a couple small holes would last? How about a 2 lb block?

Referring to a previous question just like this that I answered here just use yeast, sugar recipe and add jello to it. Why Jello? Jello will trap the co2 in a solid form and will cause a slow release which is much more stable, long lasting and will release it over a longer period of time. There you go cheap co2 that will lost a long time make several of those bottles and you could even measure it's output.

I'm still not sold on the yeast.

I would love to hear from someone what a packet of yeast + 3/4 cup of sugear & some water (& maybe even jello) will produce & what it will cost vs. dry ice.

I've still yet to try it & when I do I will share my findings on how long dry ice will last. As far as $50 a day.... I have to say that's absolutely wrong... @ least in my area. I can get dry ice .99 cents a pound like a said. I can't imagine my area needing 50 pounds of CO2!! So what i do know is 1 lb. of dry ice will produce 1 lb of CO2, it costs .99 cents & it's just a matter of controlling it's release. But what does a packet of yeast + 3/4 cup of sugar + water (& maybe jello) produce, over how long & what cost.
