Typically I will run 90-120day veg on a 16/8 for those times when I hit a 9-12 week flower I will start light dep. I have never cut it to less then 9 hours on. But yeah I agree on time. Usually if I'm not chasing genetics. I will start the beans I like from seed first run, phenom hunt those, then clone out. The clones allow me to speed up the process since it holds the mother's age. Allows harvest every 2-3 months. I would love to run a whole room of autos. Maybe if I ever find a strain I like I'll try it for my winter cycle next year.
