I used all 3 this last round. Starting with 24/0 then scaling down. Everybody has a different opinion on this, but quite honestly I don't think it matters a whole heck of a lot with autos.What light cycle u use Vapeo, 20\4? I've been going with 24\0, might have to experiment!!
Plants do behave/react differently during a dark period, but that's all I can say for sure
In my humble and unsolicited opinion, any trich production gained by this method would only be clear/worthless ones.I plan to give them 2 days of darkness prior to harvest.
If you care more about yeild than "bag appeal", as I do, I would keep blasting them with light those last two days and harvest just before lights on for maximum flavor and smell.
