I admit that I don't really see the problem, and I'll tell you: you know that a plant is still made to be outside, and the rain, wind, and humidity don't kill them. It's really when you bring them inside that you have problems related to humidity because there are fewer beneficial bacteria to protect it against rot, etc... Anyway, since it's an auto, you can easily be above the 12-hour regulation for photoperiodic plants, but you still have to be careful with the stability of the schedule. That is to say, don't suddenly increase the light time because that will cause light shock and could make the plant go to seed. However, you can always reduce the light time. Before I leave you, I would say: light degrades the terpenes responsible for flavor and THC, so the more light intensity you have, the less potent and flavorful the final product will be. After all, the difference is still small, but it's up to you to decide; I lower the light towards the end unlike others, but I've done it both ways and I chose this one. I hope I helped you anyway! 🚀
