Would be interested to hear more about your setup. There are many dangers to free-range from stepping on them to elect outlets. My GH is is a lean to against my 12x18 shed with on real wall between them [just studs]. The shed acts as a heat sync and there's a 6"stepup from the GH to shed. I have an oversized mini split unit [24k btu] to heat/cool and so far it keeps temps at 64 degrees [i can adjust up if needed] but the GH is heating to 75-80 degrees so far from the sun. I have a 130-gallon pond on the other end of Greenhouse i doubt he could fall in but it's possible.
