Cheap and easy Co2

wow skunk that's awesome. i'm gonna give that a try haha. you could brew your own moonshine and grow your own weed as part of the same project lol

I thought about 'shine before I decided to grow, believe me! But it takes so much more room to distill as much as I would drink LOL

One thing nobody has mentioned here, is that CO2 is detrimental to humans (or pets) so an excessive amount in a closed space is not good for an extended period of time.
Meaning Don't smoke a bowl, then fall asleep in your grow area.

***This was meant more for the newbs like me, excited about all the new stuff we are finding and jumping in feet first, thinking the age old "more is better" and overdoing things.

If you want a cheap and effective way to inject co2, this is the ticket. The baking soda and vinegar works but yeast is muuuch better. The reason is because yeast is actually a living organism; when it's placed in water with sugar present, it becomes anaerobic and feeds off the glucose in the sugar for energy. After consuming the sugar, it releases co2 and heat as a byproduct.
The actual lifespan of yeast is like 30 to 60 days or something like that.. but this method is really only good for a week or two tops before you should bring in a new population of yeast, and fresh sugar. For best results, buy some sort of "rapid rise" yeast as this typically contains an enzyme to increase production dramatically (check the ingredients). Hope this helped the skeptic believers

I've been using high alcohol yeast from a homebrew shop. When the bubbles die down I just pour half the bottle contents out and replace with sugary water, haven't had to buy any more yeast, as long as they have sugar they pretty much eat, pee out alcohol, exhale Co2 and make more yeast babies.
If your yeast is dying it's generally 'cos they ran out of sugar and starved...

Ive been messin w all this stuff the last 4-5 weeks (flowering)
I honestly just don't have the extra money right now for a legit Co2 setup. prob $200-$400. Also, dont wanna spend $ on a tester. That being said:
the sugar/yeast thing seemed cool at first, but its really anyone's guess how much difference it is actually making. And also very hard to guage the optimal mixture. its kinda a pain, but I still run a few bottles, and shake em a lil whenever im in there, cuz hey Why not?

Dry ice: Way too expensive to do everyday. I hung a small cooler bag w the stuff seeping out in front of a fan. the prob is, it will "melt" in abt 24 hrs. Even in your freezer overnight, it will be gone lol. As mentioned, No benefit of co2 during darkness.
*not to mention: ever go to your grocery store and buy the stuff? they keep it locked up, and it's always an issue to get it. I had one cashier asked me what i was using it for. B*^$# haha jk

Propane burner of any kind: I will run a little flame when im in there, but would NEVER EVER leave my room with an open flame burning. NEVER lol

SO, in conclusion, my experience has led me to believe Unless you have the extra $$$$ for a "real" Co2 setup (tank/regulator/controller) The BEST method of keeping Co2 in your room is just fresh/new air. and always chill w them and tell them how pretty they are.

Case closed lol

and any "result" with or without is not valid, because I know no one ran Identical conditions, with and without these methods, so its impossible to say "yeah, it worked" unless you have solid evidence.
Even a "tester" may not be accurate, only testing certain samples of air, cheap test kits, tester error, etc.

I'd agree it's only really effective for extra yield if you are prepared to throw some money at it, but for the closed spaces most of us grow in it's well worth it just to get some Co2 in there.
I reckon

Hello! Nice thread! I tried this method just today and it seems I put to much yeast and it grew in 2h so much that it went out the hole in the bottle's cap )

Too much yeast or sugar! lol! I put about 1 lb in my 1 gallon bottle every 10 days or so

i have been looking at this on youtube for quite some time.. i might have to give it a go

And any drinkers out there, a gallon of home brew wine should keep a good fizz on for 1 or possibly 2 flower cycles.
Mead (honey wine) is particularly fizzy, and tastes incredible if a small bud is dropped in when it's bottled.

1 gallon mead recipe

3 lbs honey
yeast
cup of strong tea
juice of 1 lemon
2 pints grape juice (optional)
Teaspoon molasses

Throw it all except the yeast in large pan, make it up to 1 gallon. A bit of heat to get it dissolved then when it's cooled down pour it into a sterile container, add your yeast.
It will take a day or so to really get going, but when it does it really goes for it!
When it's finished and clear (months later) syphon it off into a clean gallon bottle and leave it in the dark for as long as you can, at least 6 months. Then it's bottled into regular wine bottles, which is when you drop a little bud in, followed by a cork.
The honey and herb flavours just seem to compliment each other perfectly!

Hi all , this is my first post under this user name , for some reason the other one was not workin so i had to start a new one , lol. i lived down in ar. and there is nothing to do there so i started tinkering with moonshine , i went all out and bought buckets and bubblers , turbo yeasts the whole set up . ive recently moved back to michigan and obtained my mmmp certification. I have always wondered if the co2 produced from the spirits was enough to be benafical to my grow room . Personally i dont think the amount of it from a small 2 liter bottle would make a difference , exspeccally if you have exaust fans runnin all the time , now on the other hand when i was runnin it through the still i was making the first batches through five gallon buckets with a bubbler , i wonder if having mayby two of those goin would be good for the ladies , with the bubblers u can see thot quite a bit of co2 is bein released and since my exuast fan is mounted at the ceiling level and co2 tends to stay twards the floor cause its heavyer then it should be help full , with that being said , turbo yeast may not be the best option cause it was only living for like 5 to 7 days befor diein from the amount of alcahol it produced (not from lack of suger) . i would be really intrested in anyones opinoins on the matter . plus another concern is alcahol is seriously flamable and i run 1000s so is this dangerous as in fumes ? also another bi-product of makin alcahol is ethonal so if you are doin this oplease be safe and run it a few times through a still and throw away your tails cause its poison .... a good source is homedistillers-dot-org for information on the subject! sorry about the misspellings !!!

it would be nice if we had some solid test results, with and without these "co2 generators" (even tho it prob wouldn't hold much weight being the internet and all, and seeing some of the incorrect sugg/opinions on here lol)

The way I see it, it would be extremely difficult to add "too much" co2, when your room is ventilated. So any addition would be good.

I wanna see some jurassic park buds

Plants breathe Co2. Ergo; any addition is good.
I'd even suggest any improvement seen by yeast method is simply because there wasn't any Co2 left in the grow room as the plants use up what is naturally there so quickly.
As for it improving quantity, that needs money throwing at it imo

I have a friend who uses excellofizz pellets? i think they're called. Big blue pellets of co2 goodness that release over time im told!

if youre already puttin sugar and jeast , cant you brew beer meanwhile you supply your plants with extra co2?

If you go back a few posts, you'll find you can brew wine, beer etc...and a recipe

does that vinegar and baking soda concoction work?

I think the problem with sada and vinegar is that the reaction is instant where as with the yeast and sugar, the reaction keeps on going for weeks. I am going to get a big bucket with a tight lid, fill 3/4 with the yeast/water/sugar combo and have multiple tubes going out to the bottom of one liter bottles that are half full of water. I saw this on you tube with a 2 liter containing the mix. A tube thru the lid into the bottle but not into the solution.(tube opening stay near top of bvottle) the tube goes thru the lid of the 1 liter with water in it right to the bottm of the water. you will see a co2 bubble come up every 3-5 seconds. Run a 2nd tube from this bottle(inserting at top beside other tube but this one stays out of the water like the other one did.) the 2nd bottle is the condenser for the co2. It has to reach a setain concentration to force the bubble thru the tube. The last tube can be ties right to the basre of your plant or behind your intake fan.
