I said I would try it and return with the results and so here I am. I made 1 and placed a tube in the lid with a cup of water in the room to test every time I go in to check my babies. I place the hose into the water to make sure it is still putting out. I give the bottle a shake and place the hose back into the back of the fan.

I have had the generator in place for a few days now and have noticed a large difference. I have 16 plants in a 4'x6' area and the 1 has shown an improvement. I will be adding a second and possibly a third into the room also. I will vouch this does work and once again thanks Ninja.

you can do the same thing and get some home made wine out of it. Get a gallon of distilled water and put in a can of grape juice concentrate a packet of yeast and 3 cups of sugar. shake it up and put a balloon over the top with some pin holes in to let the co2 out . Make sure that the grape juice doesnt have any preserveitives in it. also you can use any kind of fruit juice as long as its not citrus. make sure you keep light from getting in the bottle. put it in your grow room until the balloon dosent stay inflated and then move it to a cool dark place for another 2 to 3 months and enjoy! you can pick up brewers yeast that will stay alive longer and make a higher alcohol content! Like anything you can get fancy with this, but baloon wine is a good way to kill 2 birds with one stone. happy growing

i recently started making co2 emitters... the first two bottles had a small amount of bubbles and only rose a little bit. but i just made another bottle but with a different ratio of sugar to yeast, and after only an hour it rose all the way to the top, and overflowed a little bit. the first two bottles were about 2:1 sugar to yeast, the last was about 6:1 sugar to yeast ratio.
since the last one rose more and produce more bubbles, does that mean that it's more efficient? i hope so.

The more sugar the faster the yeast get chews up. Yes it does emit more Co2, but for a much shorter period of time. So u choose how often u wana replace it.

I have a 2gal wine bottle and the only thing I did was used a fillips head screwdriver and stabbed a hole into the lid. I stuck a tube through it (oxygen tube) and used black electrical tape on the inside of the lid wrapped around the tube and pulled the tube through until the tape sealed off the hole the rest of the way. You DO NOT need the bubbler. This question has now been answered 5 times now. It is very safe to have around people otherwise wine would never be made :D It doesn't put out enough to be harmful. Even if you had 10 in a room it would do nothing to a person.

I found that just 1 jug makes a huge difference with my plants. Happy toking :D

Haha, yeah, smoking isnt, but growing is.. Dont go trying to mant things. It Gets very expensive.. :joint:

I accept with information: That piece is called a twin bubble air lock. It's used in releasing co2 from fermenting wine by home brewers. You can find them for around a $1 each at your local brew store, or at any brew supply online.

Nice write-up!

Has anyone used a ppm meter to actually measure results?

When my CO2 tanks run out, and it's "an emergency" I just light a small candle during lights on. The ppm meter proves it puts out a lot of CO2. Another option is a propane pilot light. Whatever, any sort of tiny flame will put out copious amounts of CO2. Of course it is more work, as you want to extinguish the flame nightly or after the ppm is brought up (30 mins). It's for a large flower room.

Hmm.. I better restate this--I do not recommend it, but it would work in a pinch. There. For more information on burning fuels for CO2 enrinchment,
http://www.hortnet.co.nz/publications/science/n/neder/co2_nr5.htm#top
go there. There may be other gasses emitted that are not so great. However, candles seem safe enough for humans, but I digress.

Not sure if it's been answered or not, but yes you can supply too much CO2. There is a chart somewhere, but it looks the same as every other macronutrient uptake versus plant growth chart out there--meaning growth exponentially increases with increased macronutrient, at first, then levels off, then becomes toxic and decreases. I cannot find the chart, but plant growth is 100% at ~350ppm, and increases sharply, but quickly not as rapid to ~130% at 1100ppm. It goes up slightly more, maybe ~140% up to 1500ppm, but at 2000ppm plant growth starts dropping again, as toxic levels can happen. Yes, with humans too.

I've actually used this fermentation method before I had tanks, and I'm curious if it really works.. I'm gonna do an experiment today and post some pics laters using my ppm meter.
