Home Made Co2 Tutorial

Thats just higher alcohol yeast with 'some' nutrient/energizer added.. It will never get to 23% though, (maybe 18-19%) and if you try to push the limit on what those turbo yeasts can do they ferment with alot of off flavours..
Ppl who use those yeasts though still need to add food-source, and more than just dextrose too.. The additives are to help the yeast survive higher abv, not make it an instant recipe..
 
i just bought a hydrometer and waiting on my money going into my paypal account so i can buy that turbo yeast. bitchin! do you make your own co2? have you posted up your recipe or can you suggest items/threads?

cheers, i assumed i was ready to go...thanks for letting me know!
 
I'd just get the 1lb fleishman's for $5.. Last you years, and do just as well.. Those turbo's are gimmicky, and btw your CO2 production rate will go WAY down when the abv starts climbing.. Your best bet is alot of yeast, and no higher than 25% sugar by mass (would finish at 14% with a minor lag at the end) or better yet, 20% which should finish at ~11.5% really quickly/steadily..
And hydrometers aren't really even necessary for this.. Can't hurt though, they can come in handy for certain recipes..

That's funny I thought the tutorial was vague and inaccurate. Shaking for 2 days doesn't start a yeast reaction, warmth does and it only takes about 20 minutes. Also the bottle in the tutorial is too small to produce much yeast.

I use a 1.75 L Bottle, with a hole drilled in the cap, and a piece of plastic tubing - silicone around the hole - running to the top of the canopy. Then Co2 is released above the plants (Co2 is heavier than air) and it drifts down over the canopy.

Dissolve 2 cups of sugar in 1.5 L of boiling water, let it cool to 110 degrees fahrenheit.

Add 1/2 tsp of baking soda, 1 tsp of active dry yeast, and I like to add a half packet of carnation instant breakfast (CIB) to help feed the yeast. The CIB also foams so it's easier to tell if your yeast it still active.

i have 2 bottles working, and my mix least about 2 weeks.

nice one! i think i will just go with your method...as its tried n tested...a lot of RIU members do it this way and say it works! Dont know why im bothering with the turbo yeast haha!

i will have a look for fleishman or the equivalent around my way!

thanks again!

I use a 600w hps in my room...would the constant heat not melt the tubing? Do you find it blocks out light?

I would love to see a pic of your room so i can get an idea.

I will try hunt down this CIB...born2killspam was just saying the previous page that the yeast needs more than just sugar...is this what he was taking about?

Cheers again...some great info in this thread!
 
I've done it this way over twenty years ago, before I had kids, and then resumed after they grew up.

The one question that wasn't answered was when to do it, veg or flower. I put the co2 to them from day 1. Seedlings, clones, any stage of veg(i'm 24-7) and all thoughout the budding stage. I have beautiful bushes....well except for the lowryder that I didn't know about.

The way I do it is in a 5 gall bucket with a tight lid. I drill a hole in the lid, buy a 1/4 in threaded barbed nipple and screwed it into the lid, nipple out, and attached a hose to it(this makes the fermation chamber airtight). the other end of the hose went through a milk jug cap(tightly) about 6 inches and then the cap was screwed on a milk jug 1/2 filled with water.(the hose sticks into the water a couple inches), then I put two more hoses in the airspace of the milkjug through the jug itself, being careful not to stick them in the water, and the other ends of those hoses are placed above my plants. It works great and I get about 30 days out of it. I can see the bucket swell as the gas builds, and it burps through the gallon jug.


unfortunatly I've never measured the co2 to find pmm....


great thread.
 
No baking soda.. Yeast like ~4.5pH and dislike sodium.. The Carnation is likely pretty good for them.. They like high N fertilizer too.. Typically diammonium phosphate is used..
And seasmoke, I've seen a faulty airlock blow a cap through a ceiling tile:)..
 
You can calculate how much CO2 you produced via sugar mass when its all done, but ppm is a different story.. The rate of production will be highest in the early hours/days, and slow at the end.. Especially if too much sugar is in there.. Aim for 20% sugar by mass, and you'll get rapid/steady ferments with any yeast (to about 11.5%) as long as nutrient/pH and temperature are taken care of.. Actually you can get away with a bit more if only aiming for that concentration.. If you mix it too strong, (>25% sugar with baker's yeast, slightly more with high gravity yeast) it will go to 12-14% quickly then fizzle down to 1% the rate and take for ever to complete.. Its complete when there are NO bubbles, and the solution is clear with a nice firm bed of yeast below.. This is important if you want to drink/distill your alcohol.. Unsettled wort is gross.. Safe, but might give you the shits..
The settling takes much longer if you added too much sugar or messed up another aspect because the yeast are still lingering.. Not doing enough to form visible bubbles really, but doing enough to keep things agitated on the micro level..
When the yeast starve themselves out while still healthy they tend to go dormant pretty instantly.. You want sugar supply (actually O2 supply to yeast) to be the only limiting factor for best results..
 
my hydrometer arrived today :D
gonna go buy some bakers yeast and a bucket with a lid. im still 100% sure on the tubing...can anybody upload some pics of their setup? Will my 600w hps melt/warp the plastic tubing?

thanks again!
 
Used this method with my first 2 grows. Its a neat idea but seriously its not worth it. I use Gallon water bottles with brewers yeast and a heavy amount of sugar and water. you have to change it every 5 days and i had about 8 gallon containers going at once. its a good idea but not so much worth the time.
 
You would have been producing about 750g of CO2/day using that method, but half would be in the dark hours.. The 375g during light though would be the same as roughly a 20lb tank/month..
