Anybody growing along the 42nd parallel. Long Island, NYC, NJ

Afternoon all,
Sept 28th.
Do you feel that the daylight hours are short enough to maintain a flowering mode with outdoor plants? Sunrise 6:41, Sunset 6:52 but there are dawn and dusk light exposure as well.
Up to now I’ve been covering my grow from 6pm to 6am due to my working hours. I may have to leave for a couple of days and I’m not sure if the current daylight length will be detrimental to my 6th week flowering plant if left exposed for the entire day.

Much obliged…elliot
