I started a project with a friend, and on our last outcomes we had some problems with mold and flowering times stretching weeks+ over schedule. We are running Co2 and using a 2 part fertilizer with an assortment of additives and stimulants. When in veg, they do great with good average temps., and humidity around the 70% range -- both uncontrolled except by the lights, and air intake/exaust.
The room they are flowering in is located in the same environment with only a permeable membrain blocking light so the light cycles arent effected.

In my opinion i feel if we need to run a dehumidifier on the flowering end then our mold problem would most likely go away and our flowering times would be better. Without the lower humidity in flower, transpiration is effected not allowing full benefit of each light cycle causing a slower flower rate and less potency.

If you can explain the importance of humidity and its effects id appreciate it.

What humidity ranges are optimal.
