Here in the Austin area we've had pretty mild temps this last week. GH temp hasn't dropped below 58 and about the same temp outside. Tonight it is going down to 50 so I am running one of those oil filled electric heaters. Probably will only come on a few times. The popup GH on the patio is keeping toasty with two 65 watt light bulbs. We will get some really cold winter before it's over and already had 8 freeze nights. But not down in the 20s yet. We're pretty mild compared to what most of you are posting. We've had overcast days this week but a little sun yesterday and today so that helped.
