I'm about to run my odorsok on a flower room for the first time. I have 2 flower rooms and 2 odorsoks. I will let ya know.

I like the oil-filled potable radiators you can get at any hardware or department store this time of year. They have a built-in thermostat but you may want a second for more precision.

I don't like the electric fan style space heaters because I have seen too many people dry out their plants using those things. If you use one, point it AWAY from the plants.
