The pics speak for itself nice job kidney but do it or the full grow and then well really see but don't take to heart what others say you have evidence even though small it's still evidence there is a difference in the growth between the two
Well there you have it folks. An enormous sample group with CO2 meters, a complete flowering cycle and cloned genetics. Wait a minute..... :lol:

Dude he's just starting and learning the method why are you always so high up on yourself you told me I would fail with my hydro and closet grow and look at me now growing nice thick stinky buds if you know soo much why don't you teach this is what this site us for to teach and learn not for a pissing contest it's guys like you that fustrate new growers just wanting to learn

Yeah, there's a few a-holes on here that need to get off there high horse. We are all here for the same thing. Get over your selves.
People asked for pics, so I posted pics. As I mentioned, there's most definitely a difference in just over a week.

Look at my screen name, do you think I'd have an idea of what fermentation is and isn't capable of?

Yeah, the difference definitely isn't from the fact that the plants are from different seeds.

You want to make enough CO2 to maybe make a difference assuming you're 100% dialed in and the addition of CO2 will be noticeable? Try 3 gallon batches with 5 pounds of sugar and one pack of brewer's yeast from a homebrew shop. Change weekly and repitch the yeast. Make sure never to enter your tent or closet or PC case or whatever you're growing those monsters in because there goes your precious CO2 you just made. Good luck from the a-hole who has been brewing longer than he's been growing ;).

This is what I do during veg while my plants are still below the lip of their container - Three 1gal batches going in my tent - each batch with 2 cups molasses 1.5 cups sugar and two tablespoons yeast - all batches restarted weekly. As long as the plants are below the lip of the 65g smart pot I brew in the tent - once they go above it I turn on all my fans and brew outside - seems to give a noticeable burst but I have yet to do a side by side.

Yes your always right homebrew just like you were with me

I deff will I'm still rocking the yeast method till I get it Do you have one or ever used one clonex ?
Yeah , i used to use 2 x gallon water bottles , 1 in each corner of my grow room , i had brewing kit plug in cork bubblers , they fitted exactly in the hole of the bottles where the lid went on, it was ok , didnt really notice any difference tbh though, good thing about the bubblers are you know when the mixture needs changing , 1 day i must have added to much sugar to the bottles as they bubbled over and made a complete mess , trouble is you can totally seal the bottle because blockages can occur and exsploding sugar yeast bottles would be none to pretty, anyway , as a result i had alot of sticky cleaning to do and untold ants and bugs everywhere , imo it ruined that grow , i never was happy they were totally gone , i have moved premises since , Anyway as i was having so much trouble with this method , but did not want to fork out on a valve and c02 bottle , we did an experiment at work , we had 2 air tight rooms , equal in size, 1 room had my 2 fermenting bottles froffing away and a fan on low, the other had just a fan on low , 2 co2 meters were added to each room, (the type used by border cops to find hidden imagrants in Lorries crossing from Cale) so pretty accurate , the readings on both metres were exactly the same , this proved to us that any co2 gained this way was indeed minimal, we concluded that you would need a small paddling pool full of yeast and sugar for it to be worthwhile, understand im no hater , i am a large scale grower who trys things at budget and hopes that they work , but at the same time does not kid himself , i aquired a divers bottle and valve which my local aquarium shop fills for free , they think its for my air rifles lol , i wouldnt dream of telling anyone else what to do , but passing on my knowledge may be useful to those who want to listen , Clonex.

This just proves that all of the extra CO2 produced was immediately use by the plants.

I would agree though that two 1 gallon bottles in a room would make no difference what so ever. Most people using DIY CO2 are using it in a small confined area. I use mine in a 4x4x8 tent but really only use it to cap a 3'x3'x0.5' area (4.5 cubic ft). Most people I know using DIY CO2 are in closets roughly 3x3x3. Comparing the usefulness of 2 gallons brewing in 27 cubic feet versus 640 cubic feet (8x10 room) is just silliness - there is no way just two bottles will impact 640 cubic feet - however they could blanket a 4.5 cubic foot depression extremely well.

There were no plants in the rooms, and the rooms are tiny , no larger than a broom cupboard , do your own test ,i know what i am telling you is fact, its pointless , i wish it wasnt.

Fact is that if you have two identical sealed environments and then add CO2 to one - then the one with added CO2 would have a higher CO2 concentration.

I again don't have an airborne CO2 tester but I have tested bottled CO2 side by side to DIY CO2 in aquariums and the results were the exact same. A single 2 liter bottle of brew can raise a 40g tank of water from 4ppm to 34ppm - an increase of 850%. I pump air and have plenty of surface agitation so I assume the increase isn't just gradual build up.

Regardless, my CO2 tastes better than yours

What i am telling you is the room that had the Mixture bottles in added so little co2 it was not measurable and the equipment used was of the highest standard, you do your thing , i will be over here doing mine, peace:)

You used one of these? http://www.gasdata.co.uk/products/gfm225.php

Brewing a 1 gallon batch of beer creates roughly 1.4 lbs of CO2 - 12 cubic feet. Breathing all day produces roughly 35 cubic feet of CO2. So you had two going... your detector didn't notice the equivalent of a person breathing nearly an entire day in a small enclosed area with no ventilation? I think it needs a recalibration. Or you were brewing incorrectly.

Here's the math of it -

4. FERMENTATION METHOD OF CO2 ENRICHMENT:
Sugar is converted into ethyl alcohol and CO2 when it ferments due to the action of yeast. In this method, the following ingredients and equipment are needed:
1. Suitably sized container, plastic or glass
2. Sugar, common or invert
3. Yeast, brewers or bourgelais wine yeast
4. Yeast nutrient
5. Sealant, cellophane, tape or lid
6. 1/4 plastic tubing
7. 1/4 shutoff valve
8. Balloon
9. Starter jar or bottle
A pound of sugar will ferment into approximately half a pound of ethyl alcohol (C2H5OH) and half a pound of CO2. One pound of CO2 makes 8.7 cubic feet of CO2 gas at normal atmospheric conditions. In our standard 8 X 8' X 8' grow room, you will need to generate 512 cu. ft. X .0013 (1300 PPM CO2) = 0.66 cubic feet of CO2 every four hours. It takes time for the yeast to ferment sugar, so the size of container you should use in determined by dividing the cubic feet of growing area (512 Cu. ft.) by 32 = 16 gallons.
A convenient container to use here would be a plastic kitchen garbage can. These are inexpensive and easily obtainable.
To determine how much sugar we need for six weeks of operation or until fermentation ceases, the following calculations are necessary: From the above paragraph, we need 0.66 cu. ft. of CO2 every four hours. If one pound of CO2 makes 8.7 cu. ft. of CO2, we will need 0.08 lbs. of sugar, but because every one pound of sugar only makes 1/2 lb. of CO2, we must double the amount of sugar needed, i.e. 0.08 X 2 = 0.16 lbs. of sugar every four hours. Since there are six four-hour periods in a 24 hour day, the amount of sugar we need is 0.16 x 6 or 0.96 lbs. of sugar per day.
If we round this off to one pound of sugar per day, we will need 42 lbs. of sugar in six weeks. We must consider that only 80 to 90% of the sugar will be completely converted in this length of time, therefore, we should actually use about 48 lbs. of sugar in six weeks.
The sugar solution to start with is 2 1/2 to 3 lbs. per gallon. You can use hot water to start with, as sugar dissolves faster in it than in cold water. You must let it cool to 80-90 degrees F before adding yeast to it or the yeast will be killed. Start with the fermenting container only half-full as you will be adding an extra gallon per week for 6 weeks. Begin with eight gallons per week and 24 lbs. of sugar.
To start the solution fermenting, you will want to make a "starter batch" of sugar water, yeast and yeast nutrient. To do this, use a coke or beer bottle (approx. one pint), dissolve 1/4 lb. of sugar in 10 oz. of warm water (approx. 3/4 full), add a pinch of yeast and two pinches of yeast nutrient to this sugar mixture. Place a balloon on the bottle and set in warm location, 80 to 90 degrees F, for one to two days or until the balloon expands and small bubbles are visible in the solution.
After the starter solution has begun fermenting vigorously, it is added to the main fermentation tank at the same temperature already mentioned. After a day or so, to see that the system is working properly and that CO2 is being generated, close the valve to the supply tube and, if the unit is sealed properly, the balloon should expand in a short period of time. To regulate the amount of CO2 being delivered to the plants, open the valve until the balloon is only half the size of full expansion.
The CO2 supply tube with in-line valve should have a 2" loop in it half full of water to serve as an air-lock. This loop can be held in place with tape on the side of the fermentation tank. The open end of this tube can either be positioned in front of a circulating fan or run through "T" fittings to make additional tubes, the ends of which can be positioned above your plants. Remember, CO2 is heavier than air and it will flow downwards.
Once per week, undo a corner of the Saran Wrap and add an extra gallon of sugar solution and yeast nutrient, then reseal the top with tape. Use three lbs. of sugar and one teaspoon of nutrient per gallon.
After the last gallon is added, after six weeks of operation, let fermentation continue until the balloon goes down and no more bubbles are visible in the "U" tube. When this point has been reached, taste the solution. If is it sweet, fermentation is not complete and a new starter batch should be made and added to the tank. More yeast nutrient should also be used. If the solution is dry (not sweet) like wine, fermentation has stopped and the alcohol content has killed the yeast. At this point, it's time to clean your tank and start a new batch.
The fermentation process is quite good for generating CO2 and relatively inexpensive. Regular or invert (corn) sugar is inexpensive and available. You may have to purchase invert sugar at a wine supply store. This method of generating CO2 will cost approximately 50 to 60 cents per day.
To save money on extra yeast, you can either take out approximately a gallon of fermenting liquid and save for the next batch, or start a second system identical to the first and alternate themóclean and replenish one, then three weeks later, clean and replenish the second.

So to supplement my entire 4x4x6.5 tent I would need ~10 lbs of sugar per grow ($5). To just supplement the 4.5 sq ft that I care about I need significantly less. Three 1 gal brews should easily up this tiny tiny area to over 1500ppm CO2
