I've been using 15 on 30 off for my larger ladies and my smaller veg system, similar it looks perhaps to that, I use 6 10 min feedings during the lights on period. You may want to put some more hyrdotron in that container, it will cut down on the overspray as well as help prevent light leaks into the container. I use thin rubber covers I cut myself over mine, if there is water overspray it contains it as well as stops light which stops algae.
