Gives me something to ponder for next time
If you do use dry ice let me know what it does to your humidity.
I have my fans on a controller that turns my fans on at 80 F then off at 73 F. I want to bump up the heat to go on at 85 and off at 78. I am not going to do this until I buy those throw away co2 testers to make sure there is enough co2 to make the extra heat beneficial.
The sugar yeast method did not mess with my humidity to bad. I wish I had a 20lb tank...
