This may be a dumb question, but it's one that I haven't been able to get a good answer for...
How exactly does a rack work??
I know each snake has a bin it stays in, and they are all stacked on top of each other. I also know heat tape is used, but how can you control all those snakes with just one strip of heat tape?? I've seen some of the rack setups here, and it looks like they just have the heat tape centered along the rack, winding form one shelf to the next...how does this provide for a temperature gradient??
