How do I calculate the extra light needed?

Use the `calculate_supplemental_runtime` tool by providing your available daylight hours and your target photoperiod.

Can I estimate my monthly electricity bill?

Yes, use `calculate_energy_consumption` to find your daily usage, then use `calculate_operational_cost` with your local energy price to find the monthly total.

What information is needed for a lighting schedule?

To use `generate_lighting_schedule`, you need the available daylight hours, the target photoperiod, and the time of sunrise.
