If 24/7 is working, don't change a thing. I have my water farm buckets @ 24/7 also. That bitch is looking good and ready to flower anytime. During the 'lights out' period there should be complete darkness, not even a sliver of light coming through. Choose a lighting schedule that works best for you, I have my light come on at 11 AM and off at 11 PM. Once you have the space sealed off it will probably get pretty humid in there during lights out( depends on where you live), my flower chamber got to 83% humidity so I leave my exaust fan on 24/7. During lights out the plants are getting their rest, I have my fans turn off at lights out and have them on a timer to come on a few times for 15 min just to circulate the air. I just started flowering my plants, check out my journal if you like......
