I know you are going to ask me why.....and i'm not certain but I would imagine that the heat build up inside the tube itself could cause the pyrex to explode or something.

Just go turn it back on.
Weedhound Reviewed by Weedhound on . Humidity So it's been gettin' a little chilly lately around my parts and I've had to resort to the heater to keep temps. in a good range. The problem is that my relative humidity has been showing a whole 0% for about the past week. The leaves are like paper. I have been misting the room whenever possible, bumping the RH up to 15-20% for about 15-20 minutes. How bad is this? Will the leaves recover when I get the humidity back up? Anybody else have experience with this kind of situation? The Rating: 5
