All very helpful, thank you. I'd like to move on from the cages and go with a rack. Can I ask thoughts on a "sideways" rack Vs. a "regular" w/ regard to my lower winter temps in the house? Seems like more flexwatt per inch on the sideways rack. General thoughts about sideways Vs regular?

Also, was just reading my recently purchased Barker book and they were saying (don't quote me) a basking of upper 80's.Best,
