CO2 use?????

Hi All

What improvement can I expect if I use dry ice to add CO2 to my 8 x 6 x 8 grow room?

Thanks

none, Without a monitor and constant ppm throughout the entire light on cycle, you're just wasting your time. You need a bottle/generator, monitor with photocell and a regulator if using a bottle. Anything else is a joke.

more than likely you'll be better off just sitting in the room talking to yourself (or the plants, if you do that), sing to them and that makes lots of co2.
dry ice method being feasible doesn't sound like it to me unless the room is very very sealed.

listen to this, a five gallon bucket , 2 five pound bags of sugar, . 3 bags of (active yeast). warm water , not hot about 80 f follow my directions, put water into bucket, and into a bowl, put yeast into the bowl of water, let it sit for 2 minits or more stir it up, put sugar into the bucket, stir the fuck out of it, no clumps, slowly pore the bowl of yeast water into the bucke you should start seeing the yeast eating the sugar with in 30 minits or less it swims around . and look you will see co2 being made small bubbles . this is the best formula I have found to much sugar, yeast dyes. not enough the yeast starves, you ( cant) over do the yeast the more the better, don't be stingy put some into the bucket, this trick works very well . if your room is sealed you will get a ppm over 800 co2 with in a day, that is a very large difference in yield even only 800 ppm will make a huge difference, what I use in the summer from my co2 generator , heat, issues, you can do more buckets , but 1 will get it going . 2 is for 12 by 12 rooms or pore sealed room, trust me try it thank me later ,

the co2 will be produced for about 14 days, from my home made co2 trick

how you turn that bucket off at night?

I have thought about that whenever someone tries to sell me an exhale bag. Dunno if those things only produce co2 when there is light present or what, I suppose that's possible but I dunno, I think the bag probably produces co2 night and day. of course there would be simple workarounds for that problem too.

whats the downside of a plant getting co2 24/7?

I wanna know too

Im not sure about the down side of 24/7 co2, but in response to kinddiesel, the way he is talking about can continue much longer then 14 days, just continue to add surgar, remove some water/alcohol, and add more water. (i dont really remember if this is the exact process to keep it going, you may need to add more cornmeal but i dont think so, just know it can continue, i will look into it if your going to try this.) And if you would like to remove the co2 over night just take the hose out, and put it into a cup of water out side of the room, or maybe set an exhaust to kick on over night. The plus to this method, is if your a drinker, you can make moon shine out of the water/alcohol you remove every 10 days, though a continuous mash can cause problems, so after the first 4 or 5 dont make shine anymore.

If the room were sealed well enough and the device produced enough co2 the results could vary from doing nothing to displacing o2 enough to kill anything in the room that breathes o2 I'd say but that would be a pretty high concentration of co2.depending of course.

so it's not good then to have 24/7 co2 in a room?

it's at the very least a waste because plants do not use co2 at night and could possibly be detrimental to your plants health but I'm no pro.

fair enough and cheers!

So adding an exhaust fan or intake fan, or both, set on a timer for over night, would do the trick, maybe even turn it off an hour before lights on. Then testing for co2 once or twice a day, you could figure out how exactly how much you would want to add. Im doing this my next grow.

not sure how these buckets work, I do hvac by trade and was going to do a diy bucket with motorized damper and all and figured a co2 generator and ppm monitor was best for me!

yeah it might be more work to do it this way rather then just get a co2 setup lol but prolly cheaper.

backdraft damper actually, motorized dampers run 100 bux, backdraft damper and small fan would be under 60 bux

I refer you to my first post. What sounds easier and more effective. Set a monitor and fill a bottle once a month and have it off at night and at a consistent ppm when on. Or have to mix up some goop that you have little control over and have to hook up a exhaust system and worst of all,do math? if your willing to add an exhaust, just add an intake and you have no need to supplement c02. you can exchange it for free.
