as warm as the heat tape gets I think it would do the job to keep a corm from freezing. The 70F on the heat cable is more like where you would want something to grow like starter plants. I had a heat tape half installed thawing out a friends frozen water pipe and it was working half way thru the install.. It was a good hand warmer as well. :^)
