I think the rule should be entire plant, including ALL roots are inside the tent.Idea was to have volume as a constraint. I mentioned earlier, Plants, soil/grow medium, reservoir must be in the tent. Only fan, power supplies, wiring and pumps outside tent.
Are we allowing reservoir outside now?
Height was always 24". so 1x1x2
aside from remote drivers, same should be for lights, all inside the tent.
KISS principle.
