i got these new plastic shelves at wal mart very good price for holding 28qt tubs. I would like to figure out a way to heat them efficiently. is ok to use heat tape on a plastic surface? my assumption is that if its hot enough to melt plastic its hot enough to kill a snake. This is an all colubrid rack and i dont see my temps going past 80-85 TOPS. also going to invest in a helix thermostat. i have a pic (sorry i havent taken the time to learn to post pics here but there is a link) tell me how YOU would go about heating these units.
