Urgent Force Feeding Help

Rocks are massive heat sinks. It takes a LOT of energy to warm up something with that mass just a few degrees.

I disagree at least partly with that sentence. You may be right in an absolute sense (i.e. maybe they disperse heat from other objects). However, compared to other materials (soil, wood, etc.) they radiate a lot more of the electromagnetic radiation back out as heat. If you're standing on a huge rock slab on a sunny day, you'll be much warmer than if you're standing on soil, wood, grass, etc. Of course, the degree to which they do that depends on a few factors, including color and, probably, rock type.

It only acts to radiate back when you have the full power of the sun though. A little 60w in a reflector is not sufficienty to really effectively heat a 10 lb limestone rock, especially when it's also half burried in another heatsink, soil (I'm doing bioactive setup with that rock I was referring to).
