I heard that the two combined produce co2,i have a small closet grow a few plants,and was wondering what amount to use.1tbsp bs to 3oz of vinegar was a mix i saw but nothing to show how much co2 and for how long produced.

[condor420]

doesnt xtra co2 help the flowers become more potent?

[condor420]

I wasnt givin you bad rep the question was whether or not i found that particular post helpful sorry if i hurt your feelings.Im just tryin to find out if buy buyin a 59cent carton of baking soda and a 99cent bottle of vinegar will make co2 to make my buds better,i did find some of your other info helpful as i do have a small pretty sealed in space.

ok rebull in the last couple of week iv been reading post that are either retarded, rude or incredibly childish and every time i look left i see your name, what is your problem?

as for op sorry for hijack put for a small grow just add some yeast to sugar and water , in my experience the vinegar and baking soda gives of a horrible smell.


and at the end you could end up with some home brew also

'The method of CO2 generation you are talking about produces very little CO2. For a home grower ( yes you will benefit from additional CO2) you may want to think about a simple yeast CO2 generation system. Basically use a dark 4l pal add sugar, yeast and water. Punch a small hole in the lid fit a tube in and run it to the top of the plants.

Most plants will show increased cellular activity at a CO2 concentration of 1200-1500 ppm. The air in you house is typically 400 ppm.

Thnx junior for answering my question!!!!!another cheap solution,does it give off much odor as tonto said bs & vin give a bad odor?

[junior_grower]

the yeast smells slightly of fresh bread rising ( very light)

[supermanlives]

it stinks but works ok. find a way to drip the vinegar into a bowl of baking soda.dont expect much results tho

Hey condor420!

I'm a new grower and I want to do something similar for my plants. From what I've found; best way to produce CO2 is to use tubes (for bigger grows), or if you have a small sealed off area you can use yeast and sugar as someone suggested. I think vinegar and baking soda will work too but it will probably stink a little more and I don't it will last for that long.

Since you and the_red_bull were discussing the need of CO2, I thought I'd share some background information that I found:

Inez Y. Fung from University of California, Berkeley (director of the Berkeley Atmospheric Sciences Center) said: “Plants are happy growing at a certain rate, and though they can accelerate to a certain extent with more [CO2], the rate is limited by metabolic reactions in the plant, by water and nutrient availability, et cetera.”

I've read this on other places so maybe its common knowledge but I just thought I'd provide a source so you don't think I'm making guesses. What I want to say is - if you are going to try to increase the CO2 in your grow room, the humidity and temperature will play a part in how much they will need.

In general: Our atmosphere contains about 300-400 ppm "by default". Here's some info that I found about plants and ppm:

"Successful indoor growers implement methods to increase CO2 concentrations in their enclosure. The typical outdoor air we breathe contains 0.03 - 0.045% (300 - 450 ppm) CO2. Research demonstrates that optimum growth and production for most plants occur between 1200 - 1500 ppm CO2. These optimum CO2 levels can boost plant metabolism, growth and yield by 25 - 60%."

Here's another one:

"Carbon dioxide is as essential to plant growth as the air we breathe is to us. Many plants will benefit from raised levels of carbon dioxide in the grow room. It is especially beneficial for newly rooted cuttings and vegetative growth. Some growers use CO2 enrichment throughout all stages of plant growth. Carbon dioxide can impede maturation in ripening plants, and can result in diminished production of terpines (what gives the plant it's flavor and smells) and other essential oils. Typically fresh air has about 350 ppm (parts per million) of carbon dioxide in the air. Increased levels from 1000-3000ppm will generally increase yields by 20-30% and take a couple of weeks off a three month growing cycle. For smaller areas bottled CO2 is best. In fact if it were economical, it is the best choice even for larger areas. Bottled CO2 will sink fast to the floor when released, it must be circulated through the plant canopy via carefully positioned oscillating fans to keep it from sinking."

As written in the last quote, since CO2 is heavier than air, it will sink to the ground so some sort of air circulation would be necessary. It also makes sense to lead the CO2 exhaust to above your plants, but I don't know how much this will benefit because it seem to be very hard to find information on how fast the plants will absorb the CO2.

You should also know that too much CO2 could hurt your plants, but from what I've understood that is something you don't have to worry about when using a yeast + sugar setup (since you will probably not be able to reach those numbers anyway).

I've seen formulas on how to calculate how much CO2 you need for a certain space (you will find if it using google), but that seem pretty useless since it will be hard to regulate the flow without a CO2 tank and a flow meter.

Finally, if you're going to make your own mix of yeast and sugar, there are some things that can be useful to think about.

The yeast should be for sweet bread, and yeast powder is preferred. When bringing water, yeast and sugar together, the mix will start to ferment and the sugar works as food to the yeast. Bi products will be CO2 and alcohol. The alcohol will eventually kill the yeast, so in order to get a better mix you could use wine yeast (instead of yeast for sweet bread), which is more resistant to alcohol (it survives up to 17-18% of alcohol). In order to reduce smell and get a more even fermentation you should also use dextrose instead of ordinary sugar. Additional ingredients (e.g. milk powder can be added to give the mix extra protein) can be used to maintain a balanced fermentation.

Unfortunately I can't advice you on how big of a tank you will need, but the proportions of the ingredients varies depending on which recipe you use. Search for recipes to make your own wine and you will find recipes on how to create a balanced fermentation. I have a room of 2 cubic feet and I will try using 2 x 5 litres tanks when my plants are a bit into flowering. I have no idea which kind of amounts of CO2 this will produce and I will probably not measure it either. I will just do some trial and error and hope for the best.

If you don't to go through the hustle doing all the research and buying all the ingredients, there are CO2 tablets that you can buy. You just put them in water and they will dissolve producing CO2. These are a bit expensive though.

Don't know if that helped, got a bit carried away but maybe you could use some of that info.

Respect gets Respect. Red Bull does not respect his fellow forum members yet expects respect from them.

So CO2 can definitely increase growth rate and yields in controlled environment. For a small hobby grow, it may have negligible effects (to paraphrase Red Bull ) and may not be worth the effort.

What impact on potency?
