sugar and yeast co2, whats the BEST ratio?

[cannabillion7]

what is the best ratio for the sugar and yeast co2 method. ive been using it for a while but i still cant get it down. seems like the bottles the foam up real good are made with random combos. lol!

 

[sidngroovennude]

the way i have done it in the past is 1 litre water, 1 packet of yeast, 1 cup of sugar then i just empty about half the water of daily and replace it with about 1/2 cup sugar and tepid water it seems to keep goin for a few days then dies then i just replace it, i know you can get them goin and keep them goin but i am yet to work it out i am a grower not a baker or a brewer lol, i hope sum 1 has a better answer for u cause i would like to know as well.

I used to use a 2 qt pitcher, but then i read that you need at least a gallon, about 2-3 oz of yeast and about 2-3lbs sugar, but despite some criticism it works, i ditched the 2 qt pitcher in the back yard, not really yard just small red rock gravel driveway. The yeast seemed dead but when i poured it out it sizzled like crazy! then a few dayz later the weeds that usually are not that big like 6"in, sprouted like 1 foot aroun that area, and they never get that big

what works for me...

1-gallon milk jug, 4 cups of sugar...2-teaspoons of active yeast...fill up with luke warm water untill almost 3-inches from top.....goes for about 14-days


Peace

I tryed this in my closet a month ago. I tossed the jug because I didn't keep up on it.

Copy/Pasted from the grow faq here at
https://www.rollitup.org/view.php?pg=faq&cmd=article&id=262

Use 5 or 6 cups of sugar in a 1 gallon container, make sure the container has a fitted lid. Add half a gallon of water to the sugar along with a couple of tablespoons of active yeast.Poke a small, pencil-like hole in the lid and place it on top of the container.

I don't really know how well it worked, it bubbled a bit when I shook it but I'm not sure what the difference would be between working right, and barely working.

But I feel like that is alot of sugar and I'm going to try a little mixture of my own based on some research. I'll have some numbers up soon. My cab is like 3x7 8' high. I'm gonna set up 2 gallon jugs and see how it goes.

best advice is go onto the aquatics on you tube put in home made co2 unite ive been useing them for a few months now and you do notice a differance.i alsospray with sparkleing water the ones with no addatives.

Question about using this C02 method when you have an exhaust running....

Say I put the gallon jug in one corner, and in the other there is my exhaust duct pulling air out. Does the plant have a chance to absorb any of the CO2 when it gets pulled across the plants, or does it need time to linger for it to work? I guess it wouldn't hurt to try. Anyone else do that?

Co2 is heavier than normal air. It will sink if its coming in from the intake. It will tsay near ur plants ur plants will use it. It will mix with oxygen then as it heats up. Nature takes its way. Heat rises and goes away. But co2 is heavier and will stay down.

<P>does it have to be active yeast? and why?</P>

Well i recently tried this with some active yeast and whatever and it exploded all over the place.....i think i put way too much in put half yeast of sugar and i think its alright. but yeah any yeast.

my searching has found me 2-liter/2-cups sugar/1/2-tsp. yeast (most expensive the best I beleive it goes wine ,champain ,beer,then bread,or champain first)fill water 3" from top/ shake everyday and it should last three weeks/ more sugar= more co2 at first but it burns out quicker/this mix should do it longer and steady as long as you shake everyday/and dont forget the hole/ ad tube to plants if placed to far away/us epoxy to seal. now i know how to do this but i dont know when. can u use co2 during entire grow or is it only in flowering

 

[Tronica]

use it during the entire grow.


i am using a 1 gallon / 4 cups sugar / 4 tblspn yeast

just made it earlier today so ill have a review in 3 days.

If your gonna go through all this you might as well do it right. Spend 15 bucks at brewhuas.com and get a hydrometer and a pack of turbo yeast. I use this to make 185 proof um... Fuel alchohol in my still (not hard to build you built a grow room you can make a still). The mixture you guys are talking about should get to an alchohol content of about 13% with the bakers yeast etc.. So for more co2/alchohol output use the turbo yeasts. they can tolerate an alchohol content of about 20% and have nutrients that plain sugar lacks for the yeast. Usually about 6 cups of sugar and a gallon of water will do it. just keep mixing in sugar till the hydrometer is @ 1.18. Dont fill if up all the way cause it will overflow. should last for about 2 weeks. hell if your not running it through the still use grape juice instead of water, add sugar till 1.18 on hydrometer. 2 weeks later and a drinkable sweet, but not something those wine and cheese people will like, wine.

that's awsome, im definitly gonna try this out.

Im collecting info on diy co2 for my room as the temps are usually sitting around 80-85...thanks for posting this up!

Im hoping it will look as good as khordes

I get an e-mail newsletter from Advanced nutrients on a regular basis. In one of these articles it gives a recipe for homemade co2 using fermentation. The recipe they give is:

1Qt. non chlorinated luke warm H2O
3 cups of sugar
3 tsp. or packet of yeast

mix ingredients in gallon jug
drill hole in lid of jug
screw lid on jug
insert straw or tubing into hole in lid so the end of the tube in the jug is 2 inches above solution, and seal penetration with tape

They say this will give your plants CO2 for three weeks. I am currently using and it is working. If you need more just make two or three jugs and spread them around your space. I only use one and have it behind my osc. fan. Hope this helps.

[imanoob]

hey man, nice looking plants you got there

I downloaded all the Advanced nutrients videos from youtube then watched them on the ps3...i didnt see a co2 episode so thanks for posting up the article. I will be trying this tomorrow.

I think i will try a mixture of ideas, i like satan's dalmation idea about the turbo yeast and might even try the grape juice instead of water!

 

[imanoob]

Are you still about satan's dalmation?

I have never done this kidna thing before...so did a little digging and found a good video on youtube

Starting Gravity for;
Dry Wine: 1.085 - 1.100
Medium Wine: 1.120 - 1.140
Sweet Wine: 1.140 - 1.160
Most Hydrometers are calibarated for 60 degress. Measurements taken must be adjusted to compensate for temperature.
Actual temp vs points to add;
60 degrees: Add .001
70 degrees: Add .002
77 degrees: Add .003
84 degrees: Add .004
95 degrees: Add .005
105 degrees: Add .006
Example:
Wine temp is actually 84F.
Specific Gravity is 1.100
Correction to add is .003
Adjusted SP. GR is 1.103
SG - Starting Gravity
EG - Ending Gravity
Alcohol % = SG - EG
---------
7.67
Example
SG = 1.160
EG = 1.005
(1160-1055) / 7.67
105 / 7.67
13.72
aLC % = 13.72

I was wanting to double check you rmethod;

Large pot of water (or grape juice sounds better) warming up on the cooker

Dissolve sugar and take a sample out and to cool to room temp.

Use hydrometer to check reading...if not 1.18 add more sugar and repeat reading process.

Once at 1.18, add the pack of turbo yeast? Is there a reccomended about of yeast to add to amount of liquid?

Then is that it? Just put into large bottles and leave around the room? Do you use tubing to disperse teh co2 around your plants or just in bottles with straws?

And just to confirm...keep the temps around 85-90 degrees for optimal conditions?

Thanks in advance, sorry about all the questions

This is twice as much sugar and yeast as I use, but I may give this a try.

I also add a pinch (1/8 tsp) baking soda to bring the PH up,and a tsp of carnation instant breakfast to help feed the yeast.

Yeast is activated @ 110 degrees fahrenheit by the way
