diy co2

[stinkytaco]

Whats good riu. Now ive been getting back into growing. I know a little bit about using co2 but you must have the right light spectrum an conditions or else its basically irrelevant. Waste of time An money. Now my question is. After doing some research I found some people are using a mix of yeast suger an water to simulate co2. Dose this actually work?? Supplying enough carbon monoxide in tight sealed place with air regulation. To boost more growing during the veg cycle.??? One love.

 

[GrowUrOwnDank]

Yes it really works. The yeast eats the sugar and poops out alcohol and CO2. wont hurt nothing to do it, not sure how effective it would be unless the room was sealed.

 

[Southerner]

Works if you got a completely sealed room that doesn't have an exhaust fun running. I wouldn't borher with it honestly.

I have heard of this in tents but would anyone know how to regulate c02 in a grow space that is open, using this natural method.
If I hung the mix over the plants would the c02 still fall since its heaver than air ???

I'm using a 12 gram c02 cartridge in my tent. Here is a photo guys. How many do you think it would take of these bad boys to make a tent filled around 1000ppm with these cartridges.

What do you guys think? By the way I have a 40 pack

Run an airline off your Co2 fermenting vessel, and hang a halo (the same as for watering) over each plant. Co2 is heavier than air. It's what I do, and not just for extra Co2, plants use up Co2 quite quickly so it's good to get some more in there.

Years ago my buddy an old school vodka maker allowed me to grow in his fermenting room(3mx3m(10x10)) I sealed it really well, but the gas was still not enough to make any noticable diffrence, once he shot himself, I was able to install a correct C02 system, with an improved regulator but still gave unsatisfactory results, the best in my experience has come from butane, its cheaper.. BBQ's are everywhere, and that added water and heat have proved just as useful...?

 

[crappiebait]

Hold on a minute here.

You meant to say propane & not butane I think. BOOM!

And for everyone thinking about this method for Co2, don't. It's expensive, added daily maintenance and inorder to produce enough Co2 for any noticeable difference, you would need a 55gal drum fermenting.
Save your money, wish I did.

dry ice is the simplest way to create co2 simply add water to dry ice to create co2

 

[crappiebait]

Actually, you don't even need water. As dry ice evaporates, it produces a gas instead of a liquid. That gas is Co2. That's why you never get a puddle after it has all melted. I use the left over ice from when I do my hash.

 

[hydroMD]

No you dont mainliner. And if you do its not doing a damn thing.


Go away

Gorgeous setup

I recently gave this diy co2 a go, with good results.

I now have 2 of these in my tent

Not a neat setup but it works and took a matter of 15minutes! Still pushing out co2 11 days later, with the orginal yeast mixture.

Expensive lol? I bought 280grams of yeast for $3 which will last beyond this crop.
(mind the clutter haha, this was setup stage)

I used to have a cabinet with seedlings in it and a hole the size of these in the top with a nail stuck between two boards and I would get the tip on the nail and hit it with a hammer...it'd go wooooshhhhh and be done,I went through like 30 with no noticible difference... However if your room is hottt you want CO2 to help

Just some helpful info I came across on the topic.

A few things about this, I've just been doing a lot of research on this and there is some miss(ing) information. In the air outdoors, CO2 comprises about .038% of the total gas (380ppm). If you have a closet growspace with the door open and a fan running, this allows for gas to equalize so you will have ~380ppm. 380ppm is on the low end of the continuum of most plants ability to use it as fuel for photosynthesis (which stops completely at 200ppm), plants getting sufficient light grow much heavier and faster if supplied with 1500ppm (.15%, more than 4 times atmospheric levels). CO2 is only used in the presence of light and the amount of light available directly effects how much CO2 your plant can photosynthesize: at 4600fc a plant can use up to 600ppm CO2, if you increase the light to 5500fc it can use between 1200-1300ppm of CO2, if you go over 7500fc they can use up to 1500ppm.

To do calculations of how much CO2 will be generated:
1lb of CO2 (.45kg) = 8.7 cubic feet (.246 cubic m)
1cubic foot of gas increases the percentage of gas in a 1000 cubic foot room (10x10x10) by 1,000ppm
-during fermentation about half of the sugars weight is CO2, so if you want 1lb CO2, use 2lb sugar
-To determine how much weight you need, first figure out how much light you have and find the appropriate ppm CO2. Then find cubic area of growspace. Use these: 600ppm is 1:666(if you want 600ppm, multiply cubic area by .0006, so a 1000 cubic food room requires .6 cubic feet, or .0168 cubic meters or CO2) -- for 1000ppm it's 1:1000, so multiply area by .001 -- 1200 ppm is 1:1,000,000, multiply by .0012.

-When you make your hose, puncture it up and down the length of the hose (like for a drip irrigation system) and place it above your plants (CO2 sinks).
-if you want to use CO2 outdoors (which you should!!) a large compost pile in the middle of the garden works, or in a smaller garden putting a small compost pile under every plant. This is a super easy + effective way to enrich CO2 outdoors.

-CO2 generators are VERY effective under certain conditions and at least somewhat effective in nearly all conditions.

In my 54³' area I run my CO² for 1min at 2.5³'/hr. On the indoor forums it has a CO² calculater and that's what it said is the amount of time to get it to 1500ppm 3x a day

Should last me something like 1200 days
