I guess I never bothered to look at the wattage before. I don't power the heaters up to the highest temp, but little Pelonis and the oil filled are all 1500 watts. Don't know about the heat dish, didn't look.
If I want my plant collection to survive winter, then I need to use the heaters. (I believe DH thinks it's probably cheaper than the shoes I used to "collect"). The plumerias are in the garage.
Tonight we're supposed to be in the 20s. I'll probably be up around 3 AM to check on things.
