Room heating


New Member
I've seen this "Clay pot heater" with candles so I thought of doing something of the sort for the grow box.
Not with candles, obviously, but with a cup warmer that i have. Will it work if I just take one small clay pot and put it upside down on the cup warmer? or mabye even a tin can instead of the clay pot? or will none of these be better than simply the cup warmer alone?
thanks guys
