Last winter, it was pretty cold, so in the interest of keeping the elec bill under control, I didn't heat the GH as much. Which meant, I lost about 6 tropical hibiscus and some other plants.
I just got a 45 watt solar panel setup from Harbor Freight. My husband set it up this morning, took less than an hour. Right now, the battery is charging, should be ready to go by tomorrow. I won't need to use it for heat yet, but I'm ready! Bring on the cold!
