I veg at 16/8. 16 hours on is the dead of summer around here.
I currently run my lights during the day but in future I will run at night to save a few degrees

Your plants will sleep for 4 hours minimum in a 24 hour period, regardless of whether the light is on or off. So save your money and turn the light off for 4 hours.
I run my lights for veg 6 am to 12 midnight and flower 10 am to 10 pm, being retired has advantages, I dont get up until 9am at the earliest

Yeah, but they dont have to pay for the sunshine, when they are asleep for 4 hours of it . Calling it sleep is probably wrong, they have to switch over to converting all that light energy into food/sugars, they have to do it for a minimum of 4 hours, so they can grow. If there is still light they will still shut down photosynthesis, to convert that energy already absorbed, to sugars and growing. Therefore no light is being absorbed when photosynthesis is switched to process nutrients, so no light is needed. Thatās my understanding of it

This is actually a good idea for a thread Iāve never really thought about this but itās something i need to plan out soon enough, getting some good ideas from other peopleās schedule, my plan is to try and run lights on when Iām home the most.
