co2 question

Does anyone else have the problem when they inject co2 into their grow room that it instantly jumps the humidity? When I inject co2 out of my 20 lb tank my humidity jumps to 80-90% do I have impure co2? or do you guys have a solution for this?

how quickly are you saturating the room,and what fans are on,if any.

If you pump cool gas into a warm environment, you should see condensation. Maybe run the dehumidifier when running the co2.

thats what I was thinking but I dont know if it wil dehumidify quick enough. Maybe shoudl I Point my hose into the dehumidifier so It passes throught that before it enters the rest of the grow area?
