Heating in the winter

They are cheap, gives off tons of hot air, and they pay you back some of the expenses

I've got one to heat up my basement.

It uses 1750w, heats more than a 2kw heater, and pays me back 60$/month

Ha! Not a bad idea.

Underfloor heating is the way to go, believe me. It's cheap as well. Much cheaper than those mats they sell specifically for propagation. Your root zone temps are more important than your ambient temps to a large degree.

Underfloor heating's saved my ass a couple of times. The difference in growth and health when you focus on providing heat to the roots rather than the air, is clear.

Get a roll-out mat and hook it up to an inkbird thermostat

This!

Since you are more than likely heating your house, have you thought about just melting snow in a pot? Im sure there will be lots of it close by around the house.
