You will always have some spots with a micro climate, where ever you grow your plants.
Although my thermostat is set to a certain temperature, I still have a cooler spot in front of the greenhouse door which is facing North. I take advantage of that and use it for those Orchids which need to be kept a few degrees cooler at night and still sit in the sun at day time. ( like Neofinetia falcata, and now Dendrobium kingianum.)
