  • Is humidity over 60 bad during flowering

    Not with good air flow, some prefer lower 50s or even 40s to stay safe, other say higher is safer with airflow. I had no issues at 60 with good air flow. Give the forum a search for flowering RH.

    Your temps should also be considered so that you are in the VPD range for good transpiration. I grow under LED so I like to stay closer to 60% and keep my temps around 85 but like @J232 said I have crazy negative pressure going in my room. Lights off it spikes a bit but drops to @ 50%.

    I run my 6" exhaust at max speed and have big fans above and below my canopy and also more above my lights creating a wind tunnel in my closet. Never had any mold or budrot issues (knock on wood).
