I want to express my thoughts. I believe there are other radiation emitting from sun, which we cant see, like uv and others, When its day time, there has to be more of that radiation in our atmosphere, as compared to night time where there is not even light. Somehow i feel that we should sync our day and night cycle with the sun, its not a exact science, but i believe it should have some positive effect to do so. Now in my case, the electricity rates are almost double from 6pm to 12, 6 hours, in my first grow, during veg i i was like lights on from 12 night to 6pm evening,18 hours, and during flowering, i kept it 12pm to 12am off, like that. Though it was my first ever grow, which i believe was not so good at all, So this time, i flipped on 19june, 4 plants, and i have changed my times for lights on at 6am in the morning to 6pm in the evening. This way my plants have a day when the sun is up. And they rest when the sun is down. It is just my thought that this way they will me more synced with nature. I would like to hear your inputs.
