I have the illumina so I have 3 hour sunrise 7 hours of day light 3 hour sunset then the lunar cycle for night time. Im thinking of cutting down my day duration as it maybe a little long. I also have 6 cloud periods a day with a 5% chance of lightning! :lol:

how do you do your clouds-haven't figured it out yet-as you know the damn light doesn't come with instructions
