I know that answeer I did the math.
dry ice will freeze your leafs hard ever drop a bannana in it
then shatter the bannana... as well thats a LOT of moisture.
need 0.66 cu. ft. of CO2 every four hours. If one pound of CO2 makes 8.7 cu. ft. of CO2 need 0.08 lbs. of sugar, every one pound of sugar only makes 1/2 lb. of CO2, so double the amount of sugar needed 0.08 X 2 = 0.16 lbs. of sugar every four hours.
there are six four-hour periods in a 24 hour day, so need is 0.16 x 6 or 0.96 lbs. of sugar a day.
roundoff to one pound of sugar a day,
so 42 lbs. of sugar in six weeks.
or break that down to apple wine 5 lbs of sugar {I use a little more makes a 5 gal batch} or 8-1/2 batches of wine total.
or a batch and 1/2 a week??? for a 6 week period.

you have to forgive me for I had figured it out for wine for thats what I make most.
but the numbers are correct
o thats the math for an 8'x6' with a 6' ceiling you would have to do the math to fit your spicific space
