BnB, your gh looks like mine does every November when I stuff everything in at the last minute. It's perfect!
Cheryl, I have five of these little heaters. I have two on the patio, and three in the hoop by the fence. I only fire them up when the temp is in the very low 40s, or 30s. They seem safe, plug into GFIs, and have never fallen over yet (blasted raccoons may try). I occassionally hit them with the hose, unintentionally, with no problems.
Just take the best of all our suggestions and do what you think will work best for you. The first year that I had hoops, I hardly slept when we had a freeze. Each year it gets easier because, unfortunately, it gets warmer each winter.
