It was recommended that I should place an oscilatting fan adjacent to a cooler with dry ice in it. Do you think water should be added, or just the dry ice by itself?

How could I utilize a timer, do you mean for the fan? And as far as exhaust I am not able to do alot but we have a large bedroom and my grow is in our closet which is an open faced walk in closet, so there is no door.
Would that be enough or what would you recommend?

Yes you can. Look at Dry Ice Directory - Where to buy Dry Ice to locate some.Ok, here's the question....does dry ice produce co2, and can it be used in a grow room?
To control the amount of CO2 that is released, you must control how fast it sublimates. To do this, use a cooler. Put the dry ice in the cooler and leave it open a crack to let the CO2 gas escape. Then, time how fast it takes for one pound of ice to turn to gas and adjust the position of the lid to slow or speed the process as needed. Use 8.7 cubic feet of gas per pound of dry ice to calculate how much CO2 is being produced.
sk3tch3, are you trying to say that the oxygen a plant gives off will save you from co2 poisoning, it sure sounds like that. If so, thats wrong.
Dryice can easily pass your 1500 ppm mark, and easily kill you. Do be careful.
Peace
dry ice is co2. co2 is odorless and you can die from co2 poisoning, dizziness, and light headed feelings are common before you pass out from lack of o2. luckily you plants produce o2 from the consumptions of co2, light and sugars to create photosynthesis. so you have a readily availble stockpile of o2 coming from you grow room. when using co2 tanks, or burners, it is a good idea to invest in an co2 ppm meter. co2boost.com, dry ice and ye ol yeast and sugar rarely reach more the 900-1500 ppm, unless you try to get all TTTMT (timthetoolmantaylor)

Hmm thank you videoman, you are both wise and strong in the force! Seriously though, thanx, now i'm having a hard time putting together what you said(i'm a little high), could you elaborate please?

I have about 20 years of experience with using dryice.
There is a true story floating around about a burgular, trying to escape being pursued by the police, and he runs past a parked ice cream truck, and pops open the freezer to hide inside. Well, they found him the next morning when the owner came out to start and check on his truck, the burgular died from the dryice he was using to freeze the ice cream.
Dry ice can be dangerous if you don't respect it. Dry ice produces 8.7 cubic feet of gas per pound of dry ice.
I was talking with someone else, and explained if you want to control the evaporation, you can place the dryice into a styrofoam ice chest, heat a screwdriver, and make a hole in the chest to allow the co2 to excape onto your babies.
For my purposes, I want it mostly exposed for cooling purposes. It certainly does produce some wild looking buds.
So far as how long it'll last, 50lbs (exposed) will last me about 3 days, double that if I use an ice chest. I mostly use it exposed though.
Price is a concern, as most re-sellers aren't too happy to give out wholesale pricing. They want to charge as much as possible, I've seen places charging as much as $1.50 per pound. You gotta realize that they are always working against the clock with dryice.
I am in an industry that uses alot of dryice, so I can get it wholesale very easily, and I pay about $14.00 per 50lb block.
You may think at first that even $14.00 for 3 days worth of co2 is expensive, but it really isnt when you consider it is 3 days of constant co2 with no venting needed at all, except, I do exhaust the room at the end of each light cycle.
The effects of using dryice are readily visible on the plants too. Even tanks in my opinion, dont compare to dryice.
My last grow was done using mainly dryice, and only 2 other people knew I grow, my wife and my best friend, and each and every day, the three of us would go running in there to see the difference in growth and all the resin coated buds & leaves, this grow was done using mainly a tank, and there is no comparison. This grow is boring in comparison.
If you are not using HID lighting, do not bother with co2. Simple as that.

Adding supplemental CO2 will benefit the plants only if they are CO2-limited. Which means that, at ambient CO2 levels, the canopy is light-saturated. This is pretty difficult to achieve with CFLs.

Hmmm, you are very knowledgable, thank you for sharing I could definitely learn a lot from you. Are you familiar with the "AeroGarden" by any chance? Thats what I am growing in and I am using only it(no additional lighting, etc.) in an experiment as of late, and all is going well, but, after this round I want to do what I can to maximize in yield and quality. Can I hit you up for advice every now and again?

Dude, theres a few journals here on the aerogarden. Search them out.
Feel free to keep in touch.

Well as far as light leaks the garden is tucked into an inside corner, and we keep the lights off when the grow lights are off, I also have a heavy blanket covering the window to ensure against light leaks.

Yeah I have read all the journals actually but I appreciate your knowledge from what I have read and seen in your gallery, beautiful pics by the way.
So I would hope to benefit by your knowledge and experience being applied to a quick look at the aerogarden, to see what flaws or other things you might detect that others may have missed, after all, the elder should teach the younger.......

no video that is not what im saying at all. compensating high levels of co2 with the low levels of o2 the plant gives offwill not help in anyway. i was simply stating a fact, and clearly posted twice to be cautious using co2.
most people dont have 20 years expirence with dry ice, and im sure most people dont get as elaborate as you do with it. co2 tank and regulator comes to mind.
i have used dryice, without a ppm meter. 2 lbs a day. it was my first grow and i dont know if it even helped.
im simply giving my two cents, are you trying to discredit me? it sounds like it.
anyway......
the aero garden is good to start plants, but you will quickly find you will need more room, more light and more root sapce. peace

Well iv'e actually been growing with the aerogarden personally. and to be honest it works perfectly for my individual needs. I am in the start of the flowering stage and all is well....it's a very convenient and speedy growin machine! lol

Dude, no-one is trying to discredit you at all. Your post (#15) was a little confusing, atleast to me it was. I was simply trying to clarify.
Growing indoors, in the summer months, where I live can be a struggle, I find dryice very helpful. I have airconditioning, but nothing beats dryice....imo.
