Water temperature surely effects the amount of moisture produced... though in my specific example, the scrubber type may also play a role...
diving a Mk15 in Hawaii (74 degrees F -ish) for 2 hours using Dreager DiveSorb minimal moisture was produced, the absorbent pads were damp.
Diving in 60 degree F water in little mud holes in Texas using SodaSorb for 1 hour and 45 minutes, I can literally pour water out of my counter lung!
I think the temperature difference is probably the biggest factor in regards to the difference in moisture produced.
