Green house is misleading, it's a seed starter pod for the basement. I have the light, I just need an insulated box.
Use an RTC module and an Arduino. The RTC module will wake the Arduino every 10 minutes. If the temp is too low, it will turn on a small heater. It will also check the time and turn the light on or off as needed.
The heater can be pretty simple, just run a few volts through a power resistor and blow a small fan over it.
The light is a bit more of a challenge because I need a latching power relay. I also need a way to check the state of the light, not hard, but there's a few ways to do it. It might actually be easier to hook a servo up to a light switch.
