Yeah, you got it down hoss! I would consider 15 nine a minimum, but I give them more! The more hours of light, the faster they will grow! Then you can adjust and fine-tune the hours a week or two before you put them out permanently! When it gets warm enough to where , you’re comfortable with it. A little over 15 hours is the longest day here also! I’ve never really bothered to try and match the outdoor hours before they go out. I just make sure that they don’t start popping little balls and little flowers in early June! I start them on my bedroom floor so if I go to bed late, they might get 20 hours or if I pass out on the couch they might get 24 hours! As long as they get there 15!
