Hi everybody.

I was reading up on using dry ice to help with the curing process and thaugh of something. Dry Ice is made out of liquified and frozen Co2, it evaporates into co2 gas. Could this be used to supply co2 to a garden? How expensive is it? anyone know?

Yes, it can be used in a garden. It's not cheap, I used to get the throw-back dry ice from a lab I was working in. Works ok, but it hard to dose, and is cold as ****. You could just take a chunk of dry ice and put it somewhere above the leaves of your plants. Don't let the "mist" touch the leaves, because the mist is real cold.

One problem I used to have was that water would condense all around the dry ice, which would insulate it or something and it would release real slow. Maybe that is a good thing.
You can also put it into a plastic bottle with some water in it, and then put a balloon over the top of the bottle. It will fill wil CO2, and then you can store it for short periods.

Thanks for the reply!

Reason i asked is i may have access to some from a shipping company for free to nothing, good friends with owner, i have a slight heat problem and figured it would help, is it cool enough to keep a room cold? about 10 x 10 feet. How much to you need to use ex: in lbs... at a time?

I am not sure what the density of solid CO2 os, but you could findout pretty easy. I don't think that it will keep an entire 10x10 room cool, but it won't hurt to try. Maybe put it behind a fan, that might help cooling.
If you can find out the density, then you can see how much CO2 will be put into the air.
Bottom line, any dry ice you put in there will be more than they would havenormally been getting, so it won't do bad.
