How cold is too cold for a grow tent?

  1. My tent got down to 17C the last few nights. I live on the west coast and we are having a huge cold front. The girls have been droopy in the weather. How bad is it for the overall health of the plant and size of yield?

  2. My tent gets down to 60 degrees F at lights off in the winter and the only difference is the edges of some leaves and some small areas of the bud turn a little purple.

  3. 17 C is right at the cutting point of where MJ plants should be in dark periods. Preferably you would want temps to be between 70 - 82ish dark/light respectively.
  4. Right, they're at 21C on regular nights so far this winter. But this cold front has pushed them down. I'm gonna put a heater in my room to bring it up now.
