  1. I'm growing Jack Herer under 430 HPS and I've done 1 month of flowering. I've still 1 month left before harvesting and i was wondering if it's matter if during the night humidity rise up about 60 % ?? During the day the humidity is about 30 %.
    Does it matter ??

    Thank you
  2. what are you using to circulate airflow? if you use an oscillating fan on a timer, then the humidity levels should remain reasonably constant.
  3. During the day I open the door of my closet and i have a fan, but during the night I close my door so there is no fan...
  4. i wouldn't worry about it as long as it doesn't go over 70%, mine goes as low as 25-30 during flowering and lights on.....and up to approx 50-60 at night as well as a 15 degree drop in temp.....Peace out....Sid
