Re: Lighting. 14 to 16 hours is what folks recommend but last year we used a 13w energy efficient cool white for early morn,5 am to 8am, then again just before sunset, 3 pm to 5 pm, to total only 12 hours. Had a timer with multiple settings. Our girls did not slow down one bit; no added heat, below 0F temps, and keeping 12 hours light. My geography means I start the added light late Sept. and take it out in March.
