Building a DIY co2 set up from meijer!

hey don't feel bad about your diy co2 unit.. i made a unit out of an igloo cooler and a 4 inch inline fan. the dry ice is great if your in a tiny tiny grow box but a grow room needs a bottle or a burner.. i have some pics on the diy thread.. only thing we can learn is i didn't work for that application not that it didn't work at all.. lol..

Although I haven't read all of the responses, I must chim in...My thought is to make a solution of sugar and yeast, pour solution into ...say like 2 Qt containers X 4 ( one for each corner ) and let it fizz for about ten days...and repeat, replace...anyone see anything wrong with this????
