Co2 question

[WWZEUS]

I am starting my third grow Bubblicious and Aurora Indica both from Nirvana. I have heard people talk about using Co2 on their plants using tubing and valves to release it. I know Co2 is great for plants in general, but what does it really do to them? I have two Co2 tanks at my house not huge just 2 26oz tanks they were used for a paintball gun. I have no problem refilling there is a place that does it up the st. from me and for free:thumbsup:. So here are my main questions

Is it worth using these canisters to release Co2 on my plants or is it just a waste?

Is there a valve that i can just attach to the top of the tank and release the Co2 slowly, instead of using tubing and a more complex system?


I don't have a huge grow op just 2 or three plants at a time. Can anyone provide some advice? I can put some pictures up of the 2 Co2 canisters if people need a picture to understand what I am talking about. And for anyone that responds to this thanks for taking the time out to help an up and coming grower.

You need HPS to go with that. Room temps can be run higher. Normal fresh air is about 300 PPM. That's why we vent in fresh and out hot, yes. You will need to pump that up to 1500 ppm's for 4 to 6 hours flush with fresh air and do it again. Sealed room is a must. It will get slightly better yield and take a week or so off flower time. does it sound worth the work. Only if I were a big time grower.

Now the important part. I try not to be preachy but I am. Friends almost died. I just barely saved them.

NO CO2 IN OR NEAR LIVING SPACE. That's any animals peeps or pets. That's the commandment on CO2.

CO2 is heavier than O2 and can flood a room and suffacate you. It's a painless death but death it is.

Your can may not be big enough for your room anyway. You already know how to grow and the importance of venting fresh air. If your getting good fresh air don't bother. If not , each day just release alittle over the tops when you check them. It won't hurt if it's free but it won't make but a very small difference.

26oz tanks are too small .
You need a regulator , distribution hoses , and an acurate way to monitor the ppm in the room . I use a Sentinel CPPM-1 <- not cheap . $450.00 - $600.00

With a tank system you need a controller w/ whats called fuzzy logic programing . People w/ a burner don't .

I don't agree w/ everything the other poster claims .

Sealed room = a yes .

The need to exhaust the spent CO2 = a no . Plants use the carbon in CO2 and expell their own oxygen = they make their own fresh air supply = no need for intake / exhaust. I only exhaust my room when temps reach 92 degrees or more .

Only use CO2 in bloom / flowering . And shut it off all together 2 weeks before harvest or your finished product will lack smell and flavor for some reason that I really can't explain . Maybe Rhizome can go further w/ this .

Once dialed in you can exect 10-30% more yield and 1-2 weeks sooner finish times .

1500 ppm is optimum = a yes .

As far as CO2 tocxcicity . - 1% of a given atmosphere = 10,000 ppm.
1500 ppm = 1/15 of 1%.

Humans get headaches etc... at about 3.5% or 35,000 ppm . Our blood begins to turn to gas at 5% or 50,000 ppm and we begin to die. This is almost imposible to acomplish w/ a tank system , and would take a monsterous fuk up to take place w/ a L/P - Nat. gas burner. :stoned:

LOC and Xcrispi thanks for the advice from both of you I really do appreciatte it. You two possibly just saved me some time and money. I never actually took into account that Co2 is harmful to people, completely forgot that one. Im starting to think this might be something I want to try when I have more space and have a few more grows under my belt. I thought it was going to be a little easier than explained. My area for the grow is completely sealed and but it's not in a separate room, I actually have my grow in my room (can't take risks in having friends over and have them find it in a closet) so the whole Co2 being harmful does worry me a little. When I thought of using Co2 I thought I would be able to go to Home Depot and get a small slow release valve and use a tube with holes to slow the release. Guess its a little more complicated than one would think. Thanks again both of you for great advice

That's Ok xcrispi. I was remembering things Zandor had told me in threads way back. Yes friends had monster tanks and no real regulator.

What do you control burners with ? One of my bro's want to since he has natural gas and the burners already. How do you keep rez temps down in the heat? Chillers or rez in another A/C room to circulate ?

I don't know everything but I can find almost anything out here. Glad to be straightened out. Thanks.

[xcrispi]

Not straightening anything out man .
Just agreeing to disagree as Reaper calls it .

I read the same things you had about exhausting the room every 4-6 hrs. and was told by a couple reliable sources / Rhizome - Stinkies buddy , and Dongle69 over at I/C that it's not nesc. = thank goodness . I don't need to fill my house w/ crazy budstink every 4-6 hrs. anyways .

My sentinel CPPM-1 can run either a tank system or a burner . It has progrmming for both set ups . It even has a 12v power supply that turns off the regulator when the emergency exhaust is triggerd by the remote thermostat so were not wasting CO2 while the exhaust is on .

As far as res. temps , res chillers - I had my res. outside the room and kept it recirculating to prevent root rot . But I retired my hydro gear 18 mos. ago - I found soil / soiless to be far less stressful / enjoyable . Got tired of being married to the Res, PH , PPM . CO2 also inhibits PH flux , most commonly drop when used w/ hydro systems

Here's a link to the Sentinel gear . Check it out man.

A burner is far more economical to run - but I cant afford to run a an A/C inside the room to counteract all the added heat , and I fear Nat gas / LP devices now that Im a 90% 3rd degree burn survivor .

Peace bro.

Awsome equipment and exchange of info. Maybe straightened out was wrong wording. It's hard to keep up when your out of the loop for just a little while.

So if I were to A/C a small room and go with a co2 ppm foot print of normal outside or just above I could avoid venting all together ? Or just most of the time ?

You got me thinking man. That is what's it's all about. I enjoy it.

Thanks xcrispi.

To be honest I'm not sure .
I don't know if the plants can make enough fresh oxygen on their own at lower CO2 ppm levels to avoid intake / exhaust all together . The person to ask would be Rhizome , and he's not been through here in ages . If you'd like I can email him and ask and post his response here ?

P.S Another added luxury of CO2 at 1250-1500 ppm = CO2 toxcicity happens much sooner to spidermites , fungus gnats , thrips etc... All these lil fukrs die real quick if they find they're way into your room .

Peace bro

It would be good to know maybe keep the smell down outside a room. I would think to vent at least once a day. It's easier to try than prove it can't be done.

Thanks man peace also.
