Quick heat question

Finally, it is warm enough to send my plummie cuttings. I know they need bottom heat, I don't have a heat mat, but I DO have hubby's heat belts, from his wine making stuff :) Will they work do ya think?? Until the sidewalk gets hot enough.

I don't see why not, but I am familiar with heat belts, but any heat source will work well. You've surely been patient enough! I hope you get lots of flowers this year.

Thank you...I will post pics when they bloom (will have a camera by then)
