    What are the proper humidity levels for vegitive stage, early flowering, mid flower and late flowering?
    I will be starting CO2 injection in a few days as I just transplanted my 30 day old seedlings. I'm growing in Sunshine #4 soil. They are under 1000 watt HPS with shitty bat wing reflector. I will be making my own reflector soon as I have used in past for much more even light spread without hot spots!
    My grow room is running at 82 degrees and 36-39% humidity. I know the temp is fine with CO2 injection but unsure of best humidity levels with CO2. I plan on Veging for 2-3 weeks as the Motivation and G-force are behind the Top Skunk in development. The Motivation and G-force were from feminised seeds and the Top Skunk were fron regular seeds and are showing hybred vigor and would be ready to flower in a week or so.
    Has anyone else noticed slower growth with feminised seeds?
    Thanks for your opinions!

    sure someone else can give you a more accurate answer, but for veg you should keep it around 55%-65%, and flower should be around 40%. Important thing is to avoid high humidity during flower. Several nights of 80% or higher humidity will guarantee mold in no time.

    just to set this straight, i have looked but i'm not finding humidty levels specific to CO2 use. Just asking if anybody knows if they differ from non CO2 use ie. temps can be a bit higher with CO2. So i guess i can say thanks for nothin!

    I just read for 85 degrees, 80% is the ideal for veg. 50 for flower to battle mold
