I use a co2 solenoid on a timer with my 25 lb tank that lasts me 2 weeks so you need about 6-7 tanks per grow at $24 a tank for 25lb tank.I have my timer come on 6 times a day for 2-3 minutes per on time.New co2 25 lbs tanks sell fore $185 here and about $180 on ebay plus shipping

Just out of curiosity...would it be possible to put a plastic bag, of course this is for small time growers, over each plant put in the CO2 remote, fill it up, and tie it off for a few minutes. Would that allow you to use your CO2 a bit more efficiently, instead of just hosing down the room?

Thanks for all your replies guys.

I saw this in my searching. Might have been a post on another site. Unknown poster. I use it but cannot attest to it's usefulness yet. Still trying to work out the kinks in my way under budget grow space.


Co2 from fermintation................This is for some what low levels of Co2 production. First a list of supplies.

1. A plastic 1 gallon tea jug
2. about a foot or two of fishtank hose.
3. 3 cups of sugar
4. Bakers Yeast from a regular grocery store.


Basically all u do is put the sugar and yeast into the jug, fill with warm water, to about an inch from the top. Poke a hole in the lid for the hose, make sure it's tight. Place hose alittle way in, dont touch the mixture. Shake up ur solution. Now once u got it mixed up just take the jug put it in the grow room and place the other end of the hose in a cup with very little waterjust barley cover the hose. and basically it could take from 3 minutes up to 3 days to activate the soulution. The cooler the water the longer it takes to activate. Most of the time, by the next morning just shake it, and ur hose in the glass should produce some bubbles, between 1 every 3 to 30 seconds. And the reason it's in a small cup is, one just so u know it's workin, and 2 so the Co2 can escape into the air. If u have the hose in to much water the the Co2 will disolve into the water and not the air. Co2 meters are expensive so the exact amount of Co2 added to the air is not specific, but in growth trials plants have been known to double in 3-4 weeks. Note this solution only stays active about 3 weeks, and a bigger jug will not make it last longer. To add more Co2 just add more jugs. But remember to shake the jug every day or two. With practically no overhead cost, I hope to here of some peoples trials with this info, thanx and happy growin.....

Heres another home brew for ya's......
Items Required:
* 10lb. white sugar
* 5 gallon clean bucket W/lid
* 4 1/2 gallons of water
* A piece of toast browned and hard
* A table spoon of dry active yeast (for baking bread)
First boil the water, (this will ensure clean water) remove from the heat and add the sugar. Stir until sugar dissolves. Let cool until water is room temperature (if you don't let it cool down it won't work).
After the sugar water has cooled, float the piece of toast on top of the water. Now, empty the tablespoon of yeast over the toast. After a few days, the yeast will take over the toast and start making bubbles (CO2) in the bucket. After a week, the amount of bubbling (CO2) will increase.
Keep the lid airtight on the bucket. CO2 travels up the dispersion tubing, and due to it being heavier than air, falls directly onto your plants. Timing your exhaust, is essential in maintaining an effective level of CO2.

or you could just build this



and breathe into the garbage bag once a day... don't necessarily need the airstone ;)
jump up and down while you are breathing in it to increase your % of co2 exhaled

20 oz of co2 lasts a lot longer than a day in stealth grows and small chambers. there is an adapter you can buy for the paintball tank to make the valve the same size as a regular co2 tank. than all you need is a co2 tank injection regulator. hydrofarm has a good one. look on ebay.My grow room is 36 cubic feet so i release 1.0 pound of co2 in my chamber for 45 seconds every 3 hours. tank lasts 12-14 days. the regulators are electric so they will plug right in to your climate controller. no need to waste co2 during the fan cycle.

Guys that little pissy tank is a total waste of time, I got 20lb co2 tank for 30 bucks, when it runs out i take the bottle back give em another 30 bucks and they change it for a fresh one, no deposit, only one question asked which was if this kills your tropical fish mr ngt you are not going to come back and blame us are you?

I got mine from a calor gas outlet which is an english gas outlet, but the canister they gave me had air liquide on it, people with large ponds and aquariums use the tanks for giving co2 to marine life and plants,

If I were you I'd check where you can get air liquide co2 cannisters from.

A 20lb cannister will last 174 hours used correctly in my grow space a 20oz well, who knows.

I thought this was about not dropping a lot of cash, cus it seems to be expensive to me.

not a lot of people have space for a 20 pound co2 tank anywhere in or around a stealth grow mr. nongreenthumb. Thats great you can fit a huge 20 pound co2 tank in your grow room. As for me, I choose not to have 5 years of co2 sitting around

1st time here, i have a large tank cost 30-35 bucks to fill. I use a timer set to run every hour for 2 min.10hrs. a day, works great only use co2 when the lights are on and it last me two grows before it needs a refill, 10x10x10 room. and if the room has leaks then who knows what it would be???

you can make a drip system, put some vinegar in something that will drip down and then put a bowl of baking soda under it. releases it in small amounts
