If you read my posting then you'll see that I already have pv cells and grow lights, plus the lighting is much more sophisticated than just a timer - it uses a photocell connected to an ADC plus has a time control for forced daylight hours all built into the controller. It also turns on the lights should it become dark as a result of a storm.
