i just set my set up up . . . .i can answer basics . . . .it is beneficial, up to 1500 ppm. what kind of questions do you wnat to know

my co2 dont come in a bag . . . . . . . .. i have a tank , solenoid/timer and a co2 regulator/flow meter, plus a 50 pound tank i think

whats in that bag you posted up top?

I need to understand ppm...because I've nothing to measure that...I really don't know what it is... :sad:

I'm not sure what's in the bag. I saved the link a couple weeks ago...I think I found it here somewhere on RIU...smoking and reading...never know what you're gonna get. What I do know is that its suppose to be maintenance free and last 6 months. I felt it would allow me to introduce more CO2 to my plants while I find out more on the subject.

in a very small area those will raise the level of co2 a little but not that much. I've run a bottle and regulator for the past 4 years and am about to switch to a generator and ppm controller. also I wondered how these exhale bags work at night when the plant wants o2 instead of co2. the only answer I can think of is the bag doesn't produce that much co2 to affect the amount of o2 at night.

get a c.a.p. growroom controller..top of the line is about 700$..it cuts off the exhaust fans when co2 is being released,has the fuzzylogic ppm meter in digital display,and has a photo sensitive eye that won't let the co2 cut on when the lights are on..it completely controls your plug in selanoid valve..effeciently uses the co2 ONLY when needed..the is only a good option when growing in a sealed environment...usually a tent..if ya got a big grow,a generater is usually preferred..and added bonus on the controller..it also controls your pumps,air temp/fans,and lights!

In small grow spaces, people try various things to boost CO2. The DIY yeast method is popular. Exhale bags are a little like that - they produce CO2 through a process, and it isn't a lot nor can it be regulated. If you want to spend the money, it can add a little boost. How much of a boost? That is really hard to say.

When you get into sealed environments and regulate CO2 by measuring PPM, it can be a large boost. However, then you really should have a grasp of all the limiting factors and how they balance with each other. I would even recommend some successful grows before you go that route.

Since you're growing with CFLs in a portion of a room (I checked your journal), I don't think you're in the market for $700 units and whatnot. I could be wrong, but since you are looking at Exhale bags, probably not. I would recommend that you get a handle on lights, watering, nutrients, pH, and so on if you haven't already before you worry too much about CO2. I use CFLs too, but with those, better lights would have much more of a boost than a little extra CO2.

I was looking at exhale bags because I don't have a clue about CO2 and was guided to it :mrgreen: I figured starting small is the way to go. You're right, I'm not in the market for $700 units (way too high tech for me)...it did sound good though. Something to keep in the back of my mind for later. I think I WILL go back to the yeast method and only have them in the room while they are sleeping until I get more experience and research absorbed. I'm all about the plants, just need to get this other stuff now :)

Thanks for checking out my journal too cheechako. :peace:

I did the exhale bags for about 2 years never saw a diff and know people who did the diy co2, again nothing that impressive ever came of it. Now I have seen rooms with professional co2 like tanks and pretty much what people on this thread have recommended and honestly that's the road I will be taking from here on out don't wast your time with the bags and the DIY that's all it is is wasted time.

ive heard mixed reviews about the exhale co2 bags. i too grow in a 4x4x7 secret jardin dr120 tents (one for veg one for flower). i was thinking of tossing is 2 bags per room. BUT im really unsure about it. I run 3 clip type fans in the tent, 1 6" 250 cfm booster fan for intake, and 1 8" 550 cfm booster fan for the exhaust. i know co2 is heavier than air, but wouldnt all the co2 be sucked out the exhaust booster fan? also, i have excellent negative pressure inside tent. then in my flower tent i have a HUGE ass carbon scrubber (will be mounted up top inside tent matted with a 440 cfm ventech fan. im thinking ill runn into the same problem of sucking out all the co2.

or ill just leave well enough alone and skip the whole co2 bags all together.

now my old CG runs these bags and swears by them. HUGE trees, and awesome growth.
