with too much air flow and you will be replacing the indoor air's humidity with that of whats outside.
If a surface such as plastic/glass/metal is warm on one side and cold on the other, the warm side will condense the water out of air on the warm side. same as the surface of a can of beer when taken out of the fridge on a hot day.
so this proccess will work much better at night than during the day.
daytime condensing requires a reverse method.
if you have a bucket with a lid that you fill with ice and place it in the grow room, its the outside of the bucket that will condense.
of course, if budget isnt too much of an issue then just grabbing a dehumidifier is much less work
