ok i live in a cold country and the plants are in an unheated place in the house.

the grow light has been on up till now (keeping the temperature up) but pretty soon i'm gonna need to leave the light off for periods.

what is the best way to maintain the temperature at a nice level while still providing the required darkness?

a portable heater is not an option.

thanks
