DIY: Home Made CO2 Guide

I use a couple of Co2 fire extinguishers . Just wait till they're about a foot tall and once a nite give ur growroom a little spray , as they start getting bigger increase the amount of sprays and the results will be there to see !! I also noticed that it trimmed some time off flowering .
You mean spray it on the floor or something yeah? You don't actually spray it on the plants do you? Isn't it a thick foamy substance?

should the co2 be set at the top of the canopy or above the canopy or below and should i zip my tent up when using co2 thanks again xxnijaxx

Co2 despenser should be near your plants even with the canopy, co2 drops to the floor so if your plants are up on mounts they might not suck up as much as they could if you grew em on the floor.

hey,
I just wanted to ask do you have any idea where to get/buy that Release Valve (Twin Bubble Air-Lock) & Grommet.
I mean which kind of shop and what section at store it should be?

Ninja noted on or around the first post that any local brew shop or store that supplys any kind of home brew kits, such as homemade wine or beer kits, sometimes hardware stores will carry that stuff, mine does, hell even walmart might, before you go too abunch of stores just let your fingers do the walking and pickup a phone book and call around and see if any department stores or hardware stores carry anything like that, then if all else fails try a home brew store, where they make wine and beer for people.

Hope this helps.

Great thread!! I've been looking into a homemade co2 solution for my indoor garden and this looks like the perfect solution! I've read the entire thread and have one question regarding mixture temperature. From my understanding warm/hot water is required to start the fermentation process....in order to consistently produce c02 is it necessary to keep the mixture at a warm temperature or is the warm temperature only required to kick start the process of fermentation? My apologies in advanced if this question was already answer (if it was I didn't catch it).
 
Ninja genius setup mate. Definitely gonna give it a go. I was gonna make home made cider, would the c2o from that be damaging to the plants.(is there a difference) I'd hate to see anything happening to the girls coz i was trying to hit two birds with the one stone.(making cider).

I normally keep mine at about 24 degrees which works out well cos thats about the temp of my grow room. I think anything over 28 ~ 30 ruins the yeast & Co2 production will stop.

Sorry mate, cant say with any certainty, as ive never made Cider, but to the best of my knowledge it is all the same..

Happy days, I'll give it a go then so for shits and giggles. Cheers ninja. I was thinking it was the same thanks.

To generate the Co2 necessary to supply 1500 ppm to a grow room around 250 square feet you would need a system much much larger than the one mentioned. You'd need 1/2 a pound of sugar a day and a much larger container than a 2 liter bottle. You'd need like 10- 2 liter bottles or 1 per every 25 square feet.

I use the co2 output from my homebrew beer and it's not a problem.


Didn't see this posted but to anyone having trouble finding an airlock just put a balloon over the top of the bottle and poke some small holes in it with a pin. when co2 is being produced it will partially blow the balloon up and co2 will escape out of the holes you poked. When you need to add sugar or make a new mix the balloon will deflate.

So here's my setup. I used a gallon drinking water container. It has a flip up lid and the hole is just a tiny bit bigger that airlock valve's end so it was perfect! Just close the flip up lid to shake then insert valve into grommet! :joint:

My grow is 5x3x7 so I hope I can see some improvements as half of the girls in there are at day 45 and other half are at day 30 (from beginning of 12/12). In the next few days I will fit a hose to the end of valve and attach it to my fan.

Props to you Ninja!! :bigjoint:

Very Healthy looking plants, wat strain are they?
Glad i decided to listen to my Bro and join this forum growing 5 tangerine haze plants in my closet only day 21 but looking great will be impletmenting this system of co2 tomorrow and installing metal halide for them every little bit of tweaking to produce the biggest yeild for what i am doing is greatly appreciated , Thanks Ninja +rep :weed:

Do you believe you have to have the jar sealed?

In the past I just have a bucket put sugar water yeast and put the top of bucket even with plant. Always worked for me. I read they must be anerobic to produce CO2. I dont buy this, but then I am no master chemist either. Seems to me co2 will be released in just a bowl type thing. kinda like baking soda and a vinigar drip.

I gave up on co2 as it always seemed more hassle per increase and there are many other ways to achieve big honking buds.

I have also used flour instead of sugar when it was cheaper.
yes the yeast require no oxygen to ferment. they are faculative anaerobes in that they can use oxygen to perform celluarl respiration and in the lack of, they use fermentation following a glycolysis process. The use of fermentation clears the pyruvic acid production during glycolysis and allows ATP to be formed althouh it varies from 2-6ATP per process and up to 32ATP for aerobic respiration. From the numbers alone, if oxygen is available there will be no CO2 that is formed except during the krebs cycle where it is extremely minimal
