i do 20/4 without a timer, just get them off at 8pm and back under at midnight when u go to bedIf I were one to give my plant time to rest, I'd probably go 20/4 too, but that would mean I'd have to have my lights on a timer or something, and since I'm trying not to invest too much in this project, I'm not going to go out and buy a timer.
Besides, I go to sleep around midnight, and there's no way in hell I'm waking up at 4am to turn the lights on...unless someone has already prepared for 4:20am while I was sleeping.
