Jim, yes I had grow lights but have never used a heating pad, just on the table by the window, just like I have now, I have no new seeds growing just the plants I brought into the house,some are blooming and and some are looking stressed, maybe because they see all the snow outside.
We were on Red alert for 2 days now we are on Orange, so bitter cold with the wind blowing. it is -5 right now.
