Agreed,simple, keep your on time to 4AM and change your off to 4PM
i do the same. i wake at 6 in the am so its easy to catch them just at lights on and by the time i get home from work i still have an hour before lights off. some ppl keep the light cycle on at night to help with the temp's but its up to you any 12/12 will doAgreed,
Unless ofcourse you want your ON time to be different.
I keep my ON time the same, but then i turn ON at 6pm and OFF at 6am this way if i need to do any work in my garden i can after i get home from work and dont have to wake up with the birds to do any work.
