I try to keep that as far left as reasonable so that I always have far more production than needed.since attacks will deplete those reserves. But, there's also an indicator in middle of the supply bar which shows the 'demand' level vs your total production capability. If i were to increase dwellers to max, I'd probably need to add another couple sets of rooms.food / water / power to maintain max production.

I have a ton of warehouses though filling up the bottom of the pit separated from the rest of the rooms (only connected by elevators.) The power consumption is going to be about 1 power room set (x3) for every other production room set of 3. For power to maintain all those along with barracks, warehouses, crafting rooms, etc.I run about the equivalent of 9 of the power production rooms (each 3 room wide.) I actually have more than that but, they're only 2 room wide for a bunch of them cuz i use the remaining 2 block wide slot for power rooms all way up n down along left wall in conjunction with the other production rooms.kind of hard to describe exactly.

I run a vault with about 140 dwellers (currently) and can keep food / water production maxed with 3 sets of cafeterias (each are 3 rooms wide) and same for water production. How do I come to this conclusion? Cuz there's a mod that removes that limit and people have reported this to be the issue when going much above 200.ĪS to the max # of rooms. That's the only reason I know of for them making this limit. The game starts taking too much of a performance hit when you go over 200 dwellers.
