Home made Co2

Anyone considered adding co2 tablets to their water supply? It supposed to work check these out.

Co2 can be absorbed through the roots just as efficiently as the leaves. Check this:

Hope this is of interest, let me know if it is. CHeers.

By no means am I an expert on this, but from reading the article on CO2 root absorption it states that the plant adapted to co2 water by growing smaller leaves, and transpiring less water.... the mass was in the roots rather than the leaves. I believe the result people are attempting to achieve is a boost in yield, so introducing co2 through the air would be or sounds more ideal for the result we are looking for.

You rightly say that people are trying to boost yield thunderlips, however it is important to remember that the 'yield' that we are trying to achieve is not leaf mass, but bud mass.

'Water demand varies inversely with CO2 concentration in soil. The more CO2 in the soil, the less water will be used. And, green plants not only respond to carbon dioxide taken in through their root systems, but were increasingly accepting of it.'

'In the work we saw an astounding 2866% greater weight gain in the CO2 watered plant over the distilled water plant and reduced transpiration up to 50% on some days.'

'CO2 enhancement is in the air of the greenhouse. Water is in open contact with the roots in open containers subject to evaporation making water tracking irrelevant. We conclude that our plant’s water use reduction was due to CO2 root absorption causing the stomata to close when the plant received enough CO2 through the roots. This is consistent with the literature and our hypothesis that the primary function of the stomata is to exchange water vapor for carbon dioxide and not to cool the plant as has been thought and taught.'

It seems to me that a cannabis plant watered with the CO2 tablets mentioned above would have fewer, narrower leaves than usual and because of this light penetration would be improved, giving a better yielding plant.
I am not an expert but I have grown succesfully on a couple of occasions and I cant wait to try these out.
Let me know if you have.
Hope this helps.

see thats where the test went wrong, they didnt use a plant that buds. I am assuming the less leaf mass would result in less bud mass... Its a good idea no doubt, I have even looked into a CO2 reactor in the past to add into my res. Im just not 100% positive on the result for the plants we grow.
I think if the end result was huge nugs with less leaf, its def. the way to go.

im going out to try this this co2 in a bottle.
ive got a 1 gallon apple juice jug that should work.

half way with water 1 1/2 cup of sugar, 2tbls of yeast.
shake vigorously. check for bubble . then poke hole in top for co2 to escape. then repeat when bubbles stop.

Thats what i did, I c u live in tx, DONT let any overflow or get out, It attracts them damn fire ants, WE got em bad here in ar.

any grocery store....idk that i have every seen expensive yeast..

Use a dripper and a cup with baking soda,, Then drip vinager into the cup. The area will fill up with CO2

Hi there, was checking out a few of your grow rooms and it seems you use Co2 in there, i guess this is good for photosynthesis but I was speaking to skunk and he has his own home made Co2, was just wondering how you guys make this because I was thinking of doing it myself, much love

any got an idea on how to get around the fire ant thing????

If you put a piece of dry ice into a container of some sort, poke a hole in it, and let the fog (CO2) fall onto the leaves, that'd be perfect.

It wouldn't attract any ants, and, especially if it's an indoor grow, you can use the cold air to cool the area.

I have an outdoor grow going on, so I don't really know how I'd do this, and dry ice sublimates pretty rapidly (5-10lbs in 24hrs, so faster than regular ice melts), so I wouldn't recommend getting too much of it at a time.

But it's a cheap burst of pure, cool CO2!

I need to get some brewer's yeast and make one of these long-lasting, slow-release CO2 jugs.

i can get 50lbs of dry ice for 50 dollars...
how long would 50lbs last, just using the soda bottle ballon trick, or soda bottle and tubes to plant trick.

Unless you have something that can maintain -109degF(-78degC) it will sublimate (go from solid, 'frozen' CO2 straight to CO2 gas) at a rate of 5-10lbs/24hrs, so 50lbs would last between 5-10 days.

This is why I would suggest only getting about a pound of it at a time and applying it to your plant maybe 1-3 times per week. You should be able to get it for about $1/lb, or even free if you ask the right people at the right time

i could store the 50lbs in the freezer and use it accordingly...

You would break your freezer. The thermostat is not designed to go to such a low temperature. Read up on it a bit.

wow, really, break the freezer...is there any safe way to store that in my house??
because the co2 thing is easy, but they sell no less than 50lbs...
i cant find anyplace thatll just give me a little at a time.

i use a regulator $150
co2 tank cost $30 t o refill

co2 does the job looking like ur in jarrasic park.........C02 enviroment is a big focus

you cant use it over 90 degrees ...c02 burns up.....

I was reading through some of the threads and I hear talk c02 increases yeild so im wondering is it possible to use it with a hydro systerm?

You would get more co2 from breathing in the room while you conduct this retarded third grade science experiment. If your going to waste yeast and sugar, why not just make beer in the room in a five gallon container. At least then when you realize that it isnt helping you can drink some brew and walk it off.

Here is a pic of my first CO2 system for my room. It was my old beer fermenting vessel. You can see the Fermentation Lock on top that keeps any harmful organisms from entering the system. It is a large vessel (7 gal I think) and requires very little maintenance once it is up and running. It is a good idea to cover the container with a towel as the yeast do not like the light. I had a hose that ran from the top of the fermenter to just above plant level. As the CO2 is heavier than air it falls down on the plants. One of the down sides of this system is that you cannot shut it off at night and the fans tend to blow the CO2 around. My new system (pic attached) shuts off the fans & carbon scrubber during the time it is dispensing the CO2 from the 20# tank.

I neglected to mention that the other end of the hose on the fermenter goes into a 1 gal jug filled 1/3 of the way with water which seals the other end of the hose from the creepy nasties that can get into the system. The CO2 bubbles in the jug as it comes out the hose and you can see how active the fermenter is.
