This has been the kind of weather we've been living with for months now.

Temperature: High 60's to Low 70's.
Light: sunlight TODAY through the window. Other days, cloudy and dull but supplemented by something called a light bulb.
Breeze: Only when the heat kicks on.
Fresh Air: the air filter on the furnace.

Despite all, this kind of "weather" is good enough to make a hibiscus grow and to even flower.

Wish this pretty plant had been at my house.
However, the outdoor weather this Winter has killed most of my Solar Room plants off.
Although also indoors, they lacked the nice "indoor weather" temperatures that this beauty enjoyed all Winter long.
