hummm now I like the idea and simplicity of this however I'm concerned about how pests are going to like this.....seems as it may attract flies....

haven't had a problem attracting flies you could also leave the lid on and have no holes in it and just go in a few times a day and loosen the cap to let the co2 out. the end result of the mixture is alcohol.

I was reading and reading and reading...and finally someone said it...This is the BEST way to bring co2 to you're grow room. Because it's frozen it reduces heat which is a numer one problem, its cheaper then most any other co2 applications. gasses naturally drop in elevation so hang it in a bucket at the top of the room...obviously away form the exhaust fan.

But IMHO you don't need to mess with it, if you have good ventillation fresh air brings in all the co2 you need. and i have heard reports of co2 levels during flowering actually reducing the yield. As someone once said that I dearly trust. It is hand down the LAST thing that will be of benefit to your plant. There are a million other things you could spend your time researching and implementing to improve your garden

Alright man well thank you you pretty much summed it up all in that. i guess I shouldn't worry about it and I will focus my energy on other things such as nute levels and etc. Thank you for your input.
