CO2 set up

I need to find the best set up I can for co2 for a 7'W12'L8'H (flowering room) closed system. Not looking to spend thousands but if i can find something that will work well for a few hundred that would be great. I have no experience with co2, and have been reading around a lot but for some reason it's just not clicking. If anyone has a nice system that they could reccomend or any advice on this subject it would be great.

Thanks much, in advance.

Ok, well I am prepared to spend a bit more than I initially planned, if need be I am willing to spend a G+. Please someone give me some advice on this one. BUMP>

I use ecellofizz pucks. You simply place a puck in about 100 mL and it fizzes CO2 about 1,600 ppm in a 10 x 12 space. They cost for about 15 um $60. Gives off a nice eucalyptus fragrance and it helps controlling spider mite populations.

You shouldn't have to "control" spider mites, you should erradicate them at first sight.

I'd suggest a CAP industries fuzzylogic co2 controller and a bottle system. You won't have heat issues and the fuzzylogic is the best at keeping the ppms right where you want them.

Search around I recently posted about this in advanced technique.

Also, just spending time in you grow room will up the co2, because it's what you exhale. It works by flowing over the surface of the leaf, so blowing on your plants actually feeds them.

i use sugar/yeast because its cheap as hell. but considering your willing to spend that much money hit up your welding supply and buy a tank, a regulator, and a timer. thats your best bet and itll cost anywhere from 300 and above

i did the calculations on co2 and breath here on RIU last night, its insignificant buy something to do it.

reality is if you are doing an indoor grow it is a constant battle to fend of spider mite attack especially if you have mother plants. You would have to have an absolute sterile environment to achieve complete absence of spider mites. Identifying them and controlling an infestation is a pain that most indoor growers experience no matter how much you are anal retentive in your methods.

In my first three grow houses spider mites were a nuiscence, but my last two i had no problems at all.

I started by spraying the whole house with Avid, a commercial pesticide, before i set up the rooms.

Then I sprayed everything with Einstein oil,( it's neem oil with other crap i don't know) when i first set up i sparyed everything in the house, not just the grow rooms. I'd follow each harvest with another coat in the growroom, and didn't have to spray my plants ever.

I guess if they are there already, it's really hard to get rid of them. That's what i found in my first three houses, it WAS a constant battle.

I was wondering if someone studied this topic, i'll look for that thread.

When i'm working in my room the ppms shoot up to over 2000, and the controller eventually stops dispensing co2. It's a CAP fuzzylogic system. My room is 12 x 12, and i figured it's because im in there breatheing, when you blow at a co2 meter it shoots up like crazy.

I wasn't suggesting blowing on your plants as the only form of co2 enrichment, i just thought it was interesting that my system shuts down when im working in the garden.

I'll look for thqat thread.

I would highly recommend to take a serious look at your environment first, once the enviro is right i.e. Sealed, AC, a way to deal with high or low humidity etc. it becomes easy to just plug in the co2.
Basically you will need a sealed grow space that would operate within parameters even if the higher co2 was not present.

-You need to be able to control your temps (People say from 81-85 degrees) Co2 will not be taken up at its potential at lower temps.
- With that comes higher humidity, you need a way to deal with that.
- Water and nute uptake will increase on co2
- Intake and exhaust fans need to have back-draft dampers & need to be on a timer i.e. cycle timer or a switching outlet timer, that turns the co2 off during venting.

You will need a co2 generator or tank, personal choice.
I use a tank. You will also need a co2 ppm counter & controller along with a co2 controller for the tank.

You can check my 'grow cab build' it has most of the components in it.:

Good luck mate!

go with the fizz tablets, as state before!

I'm assuming you are saying this because a 'real' co2 set-up seems to be too much hassle for you. I agree, it is a lot of hassle, so tell me, how do you maintain co2 in your environment and how do you account for the plants increasing co2 uptake during flowering, up to 20x more then in veg. How do you maintain your plants at the temps they need in order to uptake co2.
I'm just wondering if I'm too stupid to do the science on this or if maybe you have missed something?!

+1 good posts 420 time!

The tablets seem pretty lo-tech, i've never messed with them but would like to know more, i was thinking of adding an enrichment system to my veg/clone room, and tablets might be easy and cheap.

I currently run a tank with fuzzylogic in my bloom rooms.

Thanks for all of the help guys. I do have the rest of the environment pretty well situated; a/c, dehumidifier, lots of venting and timers. This is pretty much the last thing going up. I am planning on a tank system and was wondering if anyone had an estimate on the amount of co2 I will go through in a 700 cubic foot room per month. I am thinking about going with the 35lb tank. Thanks again everyone.

I am suddenly considering getting a propane co2 generator, I think that in the long run it would be cheaper and it is much easier to go purchase or refill propane tanks than refilling co2 tanks. I will still be purchasing all of the bells and whistles to go along with it, trying to decide between the cap ppm3 or fuzzy-logic ($100 more), not sure which would work better for me, anyone with an opinion on that would be great. I never hear anyone around here talking about owning the co2 generators so I'm hoping that I can find someone who does or has, and has an opinion. Thanks again.

The ppm3 needs to be reset every now and then (unplug)
The fuzzy logic one is suposed to be better.
I don't think that propane is much cheaper in the long run, but more convenient for larger ops. Not sure though, I may get corrected on that

Good luck mate,

Thanks Unity, I actually just got done reading the chapter on co2 in indoor marijuana Horticulture by Jorge Cervantes, and he did the math on generators v tanks and it came out to be much cheaper to use the generators. Also he suggests using tanks in rooms with 1000 or less watts and I will be above that. The only draw back he had to generators is heat and moisture and I have a/c and a dehumidifier so I don't think this should be a problem. The room is around 700 cubic feet so I am worried that I will have to be refilling and thus transporting these tanks constantly, which could be suspicious. Any other help would be great.

I'm probably going to get the beat down for saying this but I have been juicing my rooms for a long time---I have done at least 10 cycles with co2 and-------You don't have to vent your exhaust while the co2 is running during lights on. I run my exshaust at night for 12 hours-that's it. Unless you have major heat issues there's no need if your on the juice---you don't have to worry about mold on your buds(that's what the continuous night exhaust cycle is for) keep good airflow in your room and things will be great---all your doing is wasting co2 unless again you have a heat issue--------------I juice for 11 hours---start 1/2 after lights on and end 1/2 before lights out----the generators are great but unless your room is >1200 cubic you will run into heat issue's and will need venting and or A/C. I also don't like the yo-yo effect of your ppm's when venting--A steady 1500 ppm's will give you better results than your room going up and down the co2 ppm ladder------2cents

If you have spidermite problems, like they come back after every grow and you keep mothers, use ladybugs, depening on how big you garden is about 2 bugs per plant should keep it sparkly clean.

I could not agree more, I have ac, and do not vent when I'm around during lights on. I do however vent 15 min. every 3 hours during lights on when I'm gone. I have to do it because the f'n ppm3 likes to get stuck and if this happens let us say at 1 hour into my light cycle then I may de-plead my co2 since i"m in a sealed room . Pisses me off that the ppm3 is not more reliable
I use a switchover outlet that will turn the ppm3 off once the exhausts come on , that way it will reset the ppm3 when it switches back and I will not have a major fuck up

I'm with you thou, keep the co2 coming...
