Yea that is way high. You are asking for mold with levels that high. You want it to be in between 30-35 lower the better in flowering. That is good for vegging though.
MoZiK Reviewed by MoZiK on . High humidity I'm currently four weeks into flower with four healthy plants in my grow cupboard. During the day, the temp gets to about 80c at the highest with about 50% humidity. At night it gets down to about 65c but the humidity ramps up to 70% Will this be ok or should I try to get the humidity down? Am I likely to encounter problems? Rating: 5
