ZERAMTHEUM thanks for your answer. My GH will have a little heater on nights when it freezes, which is about 12 nights here in Central Texas. We do get a lot of nights down in the 30s, just above freezing. I will probably use mylar blankets and 65 watt bulb for those nights. So far when it's been in the 40s this method has kept the GH about 10 degrees warmer than outside. Have yet to go thru my first full winter as we just got the GH installed. So there may be surprises. It's just the 6 x 8 and now I wish it was the 8 x 10 it's so much fun. Will have to keep an eye out for algae. Haven't seen any although I had some white mold looking stuff that I think is because the compost I had been making and used wasn't quite ready. Sprayed it with chamomile tea as someone on this site recommended and its disappeared. I have been running the Clip on fan 24/7 , but glad you mentioned it because I was beginning to question if I should turn it off at night. Spider mites. Hum. Not sure I'd recognize them. I will google and take a look. I do have a couple spiders but I hope they are eating any little bugs that might be in there.
The pic of your greenhouse makes me envious. Must be the 8 x 10 !
