Under lights, I usually do 8 hours on, 16 hours off - just like a regular work day.
(Well, for some - my work days never seemed to be ONLY 8 hours!)
Your lettuce will like the cooler temps in the basement.
Oh, wow, our shortest day (sunrise-sunset, winter solstice) is a bit over 9-1/2 hours. But, at ~110 watts for the light, less hours would mean less kilowatt-hours ($$).
Anyway, thanks! - you’ve confirmed I should light-cycle lettuce too. I guess I can try 10 hours* and see how green the lettuce stays. I have enough lettuce plants, and not enough space in the basement, that I could spare one plant and keep it outside in a spot out of the afternoon sun, for a reference. When it bolts, then I’ll have seeds. :-)
*Like you, I’m not so lucky. What’s an 8 hour work day? Although these days some of mine are more like a “Mexican” schedule with a nap after a late lunch, then work late into the evening... ;-)
Geez, maybe a comma or two...
