hang some all green xmas lights around your room and get a green headlamp from the hydro store $15. you can get your chores done during the day and just poke your head in after 6.
Looking good and yeah let them finish properly.
Not trying to be a jerk but I see wasted space. There's a lot right down the middle and also in between the 2 sets of 2 tubes on either size if you're gonna run the plants kind of small like that. You're probably looking at a 25% increase in total yield if you jam more plants in there and looks like you can.
I had a 18' x 8' room a few years back with 4800 watts. I trained the plants into the aisle spaces and once in flower I had like a foot of space to walk through along the length of the room in case of some disaster.
Man that sucks!
