CO2 Methodology

So, I need to know whether utilizing carbonated water/seltzer water actually does anything to significantly increase yield? I'm in a room approx 7x8x10. Same goes w/ 'The Yeast Method'? I'm short on funds at the current time and am looking, as are most peops, for an efficient and economic way to get CO2 to my plants. Also, if I were going to use a 70lb bottle, does anyone have any insight as to how long the tank will last if ran at the appropriate 1800ppm in a room this size. When using a tank, what kind of measuring device is used? I assume it is not as expensive as the monitors used w/ a propane burner...or is it the essentially the same device? Or....wishful thinking... if anyone know where you can get a CO2 producing device that is similar to a propane burner for less than $250, let me know. I appreciate everyone's insight.:wall:

I dont like the idea of indoor propane heaters. Open flames that are not babysat scare me. I have just started using carbonated water last night. Inital results are encouraging. They seemed to have grown about 1/2 inch in 10 hours. The plants are 4 weeks old and had just gotten their first FIM this week. I saw a show on the discovery channel about ancient forests when the earth had a lot more CO2 in its atmosphere. There is an experiment in California where they pump CO2 into the forest to see what happens. The results were, the trees had a growth spurt, but after a while, they got used to the extra CO2, and resumed normal growth rates.
Granted this is a tree that lives for years and years. For an annual plant, i think this would be just fine, so long as you didnt breed seeds from plants that grew up with CO2 supplementation. Its offspring may require eleveated CO2 levels to grow normally.
Thats all i know about that.

The Yeast method has done loads for flowering imho. It also causes a stink so make sure you wash it out and redo the yeast in a bottle method but it does work. I also use sparkling Water and it sometimes leaves spotting on my leaves which I do not like as much, but it helps. Overall it will not make things grow more quickly, but it MIGHT help with yeild.

ok

c02 increases a plants growth rate
its just not always a visible increase.

carbonated water is incredibly inefficient and also very expensive

heres some options i use.

1. yeast. works VERY well consistant output as long as the liquid is kept slightly warm. they do begin to smell like rotten fruit, when this happens poor out most the liquid,
there will be sediment on bottom dont poor that out, add more warm (not hot) water then some more sugar, shake and your done.
the rotten fruit vinegar smell is a good indicater that the liquid is becomeing saturated with alchohol, and that other waste product are building up
a few days after it starts to smell BAD the yeast becomes inactive and its just rotting.

2. 2 liter soda jug filled about 3/4 with vinegar, wrap about 2-3 tbl spoons of baking soda in a coffee filter, then wrap the whole thing with waterproof tape (make sure you can fit the
roll through the mouth of whatever container you use), using a toothpick poke a few holes at the top and bottom, make a bunch, put about 3-4 at a time in the jug. DONT tighly
seal it, or it will rupture and shred your plants. the vinegar soak in slowly and hits the baking soda, c02 gets produced preassurizes the roll of baking soda and stops more vinegar
from getting in,once the vinegar is exhuasted the preasure drops and more seeps in. if the holes are right sized each package will produce more co2 than 3 sodas and last about 1-2
weeks

3. dry ice, co2 in its solid state, sublimates at room temp, to controll place in a preassure cooker on the lowest psi setting, increased preassure raises sublimation point at room temp,
slowing sublimation and making co2 release slower and more consistant. beware condensation on the pressure relief knob, cooling uccurs when the gas escapes, and can freeze
condensation sealing your preassure reliefe valve turning your preassure cooker into a sealed preassure vessel, which can become very bomblike.

4. co2 tank. ive never used these, but i do know some stuff about gasses. most important thing youll need is a co2 regulator (no you cant use an o2, or no2 regulator)
a co2 sensor that reads ppm runs about 150. although u can probly get em cheaper

a safety warning. co2 is heavier than air and huggs the ground. and can be lethal even at relativly low concentrations for those that already have o2 saturation problems
smokers, infants, elderly, asthmatics, etc...

so if you accidentally asfixiate yosef i dont want nobody huantin me :-)

haha i want to haunt someone :) i use a tank and regulater and can breathvery easily in my room but that damn ozone generator is what kills me smells like chlorine or something in the air when its on

Yes sparkling water is carbonated water hence same deal. I have stopped however as I had no "OFFICIAL" success with it, but at the same time it has not really harmed my plants in ANY way. I also made this C02 container for my grow which actually works better than any other c02 method I have tried aside from gettin a huge c02 tank.

I made it out of old parts of a hydro pot. There are mini drip holes in the tube which release the c02 around the base of my plant.

The yeast method is a waste of time IMO. I used to run two 5 gallon buckets of yeast in a 4x8x8 enclosed area and one day decided to get a test kit to check the amount of CO2, to my surprise it was only at 500PPM. This was checked 3 days after making a fresh batch when they were pumping CO2 at full force.

Okay - I run a 4x4x7 tent, and a 20lb. bottle of CO2 lasts me about a week, keeping it steady at 1500PPMs (Sentinel CHHC-1, and the CO2 only runs when the lights are on during 12/12).

I got tired of filling up the bottles (expense, and a security issue), so I bought the CAP Gen-1 generator ($315, delivered to my door, and they messed up and sent me the four burner one, which produces 13 cubic feet/hr. of CO2), and am currently in the process of installing it and pumping the CO2 from it into my tent.

Figure a 20lb. bottle of propane should last me a couple of months, and there's nothing conspicuous about getting a propane tank refilled.
