I have this small greenhouse that i'm using to keep my plants dormant this winter. However, it's getting so cold this week that i'm getting nervous for my plants. This morning when I woke up my thermometer was reading 23°
I've shared a picture so you can get an idea of the size. I'm just hoping to keep it around 30°
As you can see, I put little votive candles in there on occasion to try and help keep them warmer. Unfortunately, I don't think it's working well enough with this cold snap we appear to be having here in Louisville, KY.
Any suggestions are appreciated. Thanks in advance, guys!
